Canada added more than 2 GW of solar capacity in 2024, bringing total installed solar to over 6 GW — but the compliance framework a solar installer must navigate is not national. It is ten different provincial frameworks, each with its own net metering rules, electrical authority, capacity limits, and credit rates. A system design valid for a Hydro One customer in Ontario may violate the rules that apply to an ENMAX customer in Alberta, and the BC Hydro program is undergoing its most significant structural change in a decade.
This guide covers the full Canadian compliance stack: federal jurisdiction and electrical code, provincial net metering programs with current capacity limits and credit rates, federal and provincial incentives as of April 2026, licensing and permitting requirements, and the step-by-step interconnection process.
Provincial Rules Vary Significantly — Verify Before Designing
What is valid in BC will not apply in Ontario or Quebec. Net metering credit rates, system size caps, utility application processes, and even the electrical inspection authority differ by province. Always confirm the current rules with the specific utility before finalising system sizing or purchasing equipment — several provincial programs changed their rate structures in 2025–2026.
Canada’s Solar Regulatory Framework
Federal vs. Provincial Jurisdiction
Canada does not have a national net metering law. The federal government, through Natural Resources Canada, plays a supporting role: funding research, publishing guidelines, and administering incentive programs. The Canadian Electrical Code (CSA C22.1) is the national technical standard for electrical installations, but it is adopted and enforced by each province individually.
Grid connection, net metering, and utility interconnection are regulated at the provincial level under each province’s energy legislation. This means an installer working across provinces must understand the rules in each jurisdiction independently.
| Jurisdiction | Role |
|---|---|
| Federal — Natural Resources Canada | Research funding, incentive programs, renewable energy statistics |
| Federal — Canada Revenue Agency | Clean Technology Investment Tax Credit (businesses) |
| CSA Group | Publishes CSA C22.1 Canadian Electrical Code and equipment standards |
| Provincial energy regulator | Sets net metering rules, capacity limits, credit rates |
| Provincial electrical safety authority | Administers permits, inspections, contractor licensing |
| Utility (regulated or deregulated) | Manages interconnection applications, metering, billing |
Provincial Net Metering at a Glance
Ontario, BC, and Alberta account for the majority of Canada’s installed solar capacity. Ontario alone represents roughly 85% of national solar generation — a legacy of its former feed-in tariff program and its large commercial and industrial base.
| Province | Primary Utility | Max System Size | Credit Rate | Credit Rollover |
|---|---|---|---|---|
| British Columbia | BC Hydro | 100 kW nameplate (new Self-Gen rate from July 2026) | 10¢/kWh export (new rate) | Annual payout |
| Ontario | Hydro One / LDCs | Up to 500 kW | Retail rate (~$0.14–0.15/kWh) | 12 months |
| Quebec | Hydro-Québec | Up to 1 MW (expanded 2026) | kWh credit at avg. supply cost | 24-month reset |
| Alberta | ENMAX / ATCO | Up to 5 MW (micro-gen regulation) | Retail rate (small); wholesale (>150 kW) | Monthly |
| Saskatchewan | SaskPower | 100 kW | 7.5¢/kWh export until March 2029 | Non-expiring |
| Manitoba | Manitoba Hydro | 100 kW | $0.04390/kWh export (net billing) | Monetary credit |
| Nova Scotia | NS Power | Up to 27 kW (residential); up to 1,000 kW (commercial) | Retail offset | Annual bank |
| New Brunswick | NB Power | 100 kW | Retail | Annual reset (March 31) |
| Prince Edward Island | Maritime Electric | 100 kW | Retail | Annual (Dec 31) |
| Newfoundland & Labrador | NL Power / NL Hydro | 100 kW | Wholesale rate at year-end | Annual |
Net Metering by Province
British Columbia — BC Hydro and FortisBC
BC Hydro’s net metering program is undergoing its most significant change since it launched. The BC Utilities Commission (BCUC) approved BC Hydro’s application in March 2026 to replace the current Net Metering Service Rate with a new Self-Generation Service Rate, effective July 1, 2026.
Under the current program (closed to new customers July 1, 2026): Surplus generation is banked as kWh credits that offset future consumption. On the anniversary date, any remaining positive balance is paid out at market price.
Under the new Self-Generation Service Rate (from July 1, 2026): New customers and existing customers who received BC Hydro’s solar rebate will receive a flat rate of 10 cents per kWh for all electricity exported to BC Hydro’s grid. All other existing net metering customers have a 10-year transition period before moving to the new rate.
The nameplate capacity cap of 100 kW remains for individual systems, but the new framework shifts emphasis from equipment capacity to limiting the volume of net injections to the grid. A new Community Generation Service Rate allows multiple customers to share a single facility and sell up to 2 MW collectively at 10 cents per kWh.
FortisBC (serving southern interior BC) operates its own net metering program with a 50 kW capacity limit. Surplus energy is banked and applied to future bills; year-end credits are paid at FortisBC’s avoided cost rate.
BC Hydro Rebate: Up to $10,000 (Active)
BC Hydro offers up to $5,000 for eligible solar PV installations and an additional up to $5,000 for battery storage enrolled in the Peak Saver program. Pre-approval is required before purchasing equipment. From June 1, 2026, installations must be completed by a Home Performance Contractor Network (HPCN) member to qualify. Receiving the rebate means you transition to the new 10¢/kWh Self-Generation rate from July 1, 2026.
Ontario — Hydro One and Local Distribution Companies
Ontario’s net metering program operates under O. Reg. 541/05 (Net Metering), administered by the Ontario Energy Board. Every Local Distribution Company (LDC) in Ontario is required to offer net metering to eligible customers.
Capacity limit: Up to 500 kW for most system types. Recent rule changes removed the previous cap for commercial systems in some categories.
Credit rate: Credits are applied at the full retail electricity rate — currently approximately $0.14–$0.15 per kWh for residential customers — covering all volumetric electricity charges. Transmission, distribution, and regulatory charges are not included in the credit calculation.
Credit carryover: Surplus kWh credits carry forward for up to 12 consecutive months, then expire. System sizing should account for this — consistently oversized systems will lose unused credits each year.
Participating LDCs include Hydro One, Alectra Utilities, Elexicon Energy, Hydro Ottawa, Toronto Hydro, and North Bay Hydro, among others. Each LDC processes its own interconnection applications.
Eligible generation sources: Solar PV, wind, water, agricultural biomass, and biogas.
Ontario’s Home Renovation Savings Program (HRSP), launched January 28, 2025 and running through November 2026, offers $1,000/kW for solar installations (up to $5,000 for panels, $300/kWh for batteries). Note: the HRSP requires load displacement operation — net metering is not eligible under this stream. Customers must choose between HRSP rebates and net metering participation.
Quebec — Hydro-Québec
Hydro-Québec is the sole electricity distributor in Quebec. Its net metering option — formally the Net Metering Rate Option — underwent a major expansion in early 2026, increasing the maximum eligible system capacity from 50 kW to 1 MW. This expansion makes large commercial rooftop systems viable for the first time in Quebec.
How credits work: Surplus electricity exported to the Hydro-Québec grid is converted to kWh credits at the average cost of electricity supply set out in the Electricity Rates. Credits accumulate in a surplus bank and can be applied to future consumption. The surplus bank resets to zero every 24 months — any unused credits are paid out at the supply cost rate and the bank zeroes.
Application: Customers apply to Hydro-Québec for a connection agreement before installation. The utility performs an interconnection study for larger systems and issues a connection agreement. Inverters must comply with CSA and Hydro-Québec’s technical requirements.
New solar grant (April 2026): Hydro-Québec launched a grant of $1,000 per kW installed, covering up to 40% of eligible project costs, effective March 31, 2026. For a typical residential system, this equates to $5,000–$6,000. Eligible systems must have been installed on or after June 30, 2025, and require official grid connection authorization from Hydro-Québec.
Quebec’s 24-Month Credit Reset
The 24-month surplus bank reset is unique in Canada and affects system sizing decisions. A system that consistently over-generates relative to consumption will lose credits at the 24-month mark. Size to approximately match annual consumption rather than maximising generation, unless the commercial rate structure justifies a larger system.
Alberta — ENMAX, ATCO Electric, and the Micro-generation Regulation
Alberta operates under a deregulated electricity market. Solar connects through the provincial Micro-generation Regulation, which sets the framework but leaves credit rate negotiation to the customer’s electricity retailer.
Capacity limit: Up to 5 MW — the highest cap in Canada by a significant margin. This makes Alberta uniquely suited for large commercial and industrial rooftop solar projects that would exceed the cap in other provinces.
Small micro-generators (under 150 kW): Credited for exports at the retail rate agreed with their electricity retailer, applied monthly. This is functionally equivalent to net metering.
Large micro-generators (150 kW to 5 MW): Credited at the hourly wholesale market price for electricity injected into the grid. Wholesale pricing introduces revenue variability that smaller systems do not face.
Distribution companies: ENMAX Power serves Calgary customers. ATCO Electric serves rural Alberta. FortisAlberta serves much of the remainder of the province. Each distribution company handles the technical interconnection — the credit arrangement is between the customer and their chosen retailer.
Alberta has no provincial solar rebate program for residential customers. However, the Clean Energy Improvement Program (CEIP) operates across 23+ municipalities, financing solar installations through property tax bills at competitive rates and covering up to 100% of project costs.
Saskatchewan — SaskPower
SaskPower operates the provincial net metering program with a 100 kW system cap. The credit structure changed from the previous program: customers now receive 7.5 cents per kWh for surplus electricity exported to the grid, compared to SaskPower’s residential retail rate of approximately 14 cents per kWh.
This below-retail export credit rate means Saskatchewan customers recover costs primarily through self-consumption rather than grid export — system sizing should reflect actual on-site consumption patterns.
Credit carryover: Credits for customers who signed up after November 2019 do not expire. Credits carry forward for the life of the account.
No provincial rebate: SaskPower does not offer rebates or grants for residential solar panel installation.
Manitoba — Manitoba Hydro
Manitoba Hydro operates a net billing program rather than true net metering — an important distinction for system economics. Surplus electricity exported to the grid is purchased by Manitoba Hydro at the excess energy price, currently $0.04390 per kWh (updated annually to March 31). This is significantly below the residential retail rate of approximately $0.10–$0.11 per kWh.
Capacity limit: 100 kW for net billing participation.
Monetary credits: Unlike kWh credit banks in other provinces, Manitoba Hydro issues monetary credits for surplus exports, applied to the customer’s account.
Rebate program — Efficiency Manitoba: Offers $0.50 per DC watt installed, up to 10 kW and a maximum of $5,000 per residential property. Commercial customers receive $0.50 per DC watt with no pre-approval required for systems under 100 kW. This rebate remains one of the more straightforward programs in Canada.
Manitoba’s Net Billing Rate
At $0.04390/kWh for exports vs. roughly $0.10–$0.11/kWh for consumption, the Manitoba export rate is approximately 40–45% of the retail rate. Self-consumption is the economic priority. Design systems for high self-consumption ratios rather than maximising export.
Atlantic Provinces — Overview
Nova Scotia (NS Power): Residential customers can participate in the Self-Generating Option for systems up to 27 kW without applying. Surplus energy is banked monthly against future consumption; any positive balance at year-end is reset. Commercial systems from 27 kW to 1,000 kW can apply for commercial net metering. NS Power’s credit system is applied at the retail rate offset but demand charges still apply for commercial accounts.
New Brunswick (NB Power): Net metering for systems up to 100 kW using renewable sources (solar, wind, biomass). Credits apply at retail rates. Surplus credit balances reset on March 31 each year — unused credits are forfeited. The Total Home Energy Savings Program offers up to $3,000 for eligible solar installations (minimum 1 kW, maximum 15 kW).
Prince Edward Island (Maritime Electric): Net metering for systems up to 100 kW. Systems above 30 kW may require three-phase power. Credits accumulate through the year and reset December 31; no cash payout for unused credits. The PEI Solar Electric Rebate Program provides $1,000 per kW DC installed for residential customers, capped at $10,000 — one of the strongest provincial rebate rates in Canada.
Newfoundland & Labrador: Both Newfoundland Power and NL Hydro offer net metering up to 100 kW. Year-end surplus credits are paid at the wholesale electricity purchase rate rather than the retail rate. Newfoundland’s low electricity rates (one of the lowest in Canada) reduce the financial payback of solar relative to other provinces.
CSA C22.1 Canadian Electrical Code — Solar Requirements
What Is CSA C22.1?
The Canadian Electrical Code, Part I (CSA C22.1:24, 26th Edition) is Canada’s national standard for electrical installations. CSA Group publishes the code, which is adopted by each province and territory with jurisdiction-specific amendments. Every solar PV installation in Canada must comply with the CEC and the local amendments in the applicable province.
Section 64 covers renewable energy systems, energy production systems, and energy storage systems. The 2024 edition brought significant revisions to Section 64, including:
- A new subsection specifically addressing residential occupancies
- Updated PV system requirements for DC arc-fault protection
- Refined energy storage system (ESS) requirements
- Clarified rules for AC-coupled systems and hybrid inverters
- Updated rapid shutdown-equivalent requirements for rooftop systems
Key Section 64 Requirements for Solar PV
| Requirement | Detail |
|---|---|
| Inverter certification | Must be certified to CSA C22.2 No. 107.1 or UL 1741 by an SCC-accredited body |
| DC disconnect | Readily accessible, lockable disconnect required at the array |
| AC disconnect | Service disconnect from utility must be accessible to utility personnel |
| Backfeed protection | Anti-islanding protection required on all grid-tied inverters |
| Labelling | PV system components must be labelled per CEC requirements — system disconnects, conductors, and equipment |
| Grounding and bonding | System grounding and equipment bonding to CEC specifications |
| Conductor sizing | DC conductors sized for 125% of rated short-circuit current |
| String protection | Overcurrent protection required per CEC where multiple strings combine |
| Maximum system voltage | Residential systems typically 600V DC maximum; commercial systems may qualify for 1000V DC per provincial adoption |
Equipment Certification
All electrical equipment used in solar installations must be certified by a body accredited by the Standards Council of Canada (SCC). Acceptable certification marks include CSA, cUL, cETL, and cULus. Equipment purchased from international markets without SCC-accredited certification marks is not legal for installation in Canada, regardless of other certifications it may carry.
Provincial Adoption and Amendments
Each province adopts the CEC with a local amendment schedule. Key variations:
- British Columbia: Technical Safety BC enforces with BC-specific amendments; BC also requires the BC Building Code to be considered for roof penetrations and structural loading.
- Ontario: Electrical Safety Authority enforces the Ontario Electrical Safety Code (which adopts the CEC with Ontario amendments).
- Quebec: Régie du bâtiment du Québec enforces via the Code de sécurité with Quebec-specific requirements.
- Alberta: The Safety Codes Act and Alberta Electrical Utility Code apply.
Installers working across provinces must confirm which edition of the CEC is in force and which local amendments apply before finalising system design.
Federal Incentives — 2026 Status
Canada Greener Homes Grant: Closed
The Canada Greener Homes Grant stopped accepting new applicants on March 31, 2024, having issued nearly $1.8 billion in grants to over 500,000 homeowners. The maximum grant was $5,000 per household. Existing approved applicants had until December 2025 to complete their projects and claim their grant. No new applications are accepted.
NRCan has announced intent to launch a Greener Homes Affordability Program in 2026 targeting low-to-median income households, but program details and funding amounts had not been confirmed as of April 2026.
Canada Greener Homes Loan: Closed
The Canada Greener Homes Loan program — which offered up to $40,000 interest-free for 10 years — stopped accepting applications on October 1, 2025. Over 120,000 loans totalling $2.9 billion were issued before the program closed. Existing approved borrowers continue repayment under their existing loan agreements.
Clean Technology Investment Tax Credit (CT ITC) — Active
The Clean Technology Investment Tax Credit is the primary federal solar incentive currently available, but it applies only to businesses, not residential homeowners.
Rate: 30% refundable tax credit on the capital cost of eligible clean technology property, including solar PV systems, wind energy systems, stationary electricity storage, and low-carbon heating equipment.
Phase-out: The 30% rate applies through December 31, 2033. In 2034, the rate drops to 15%. The credit expires December 31, 2034.
Eligibility: Taxable Canadian corporations and mutual fund trusts that are real estate investment trusts. Canadian-Controlled Private Corporations (CCPCs) can claim the credit, making it accessible to small and medium solar contractors and commercial property owners.
What qualifies: Solar PV systems installed and available for use after March 28, 2023. The system must be used in Canada and meet prescribed equipment standards.
Domestic content consultations: In February 2026, the Department of Finance launched consultations on introducing domestic content requirements for the CT ITC and the Clean Electricity ITC. If adopted, these requirements could affect project economics for installations using imported modules or inverters.
CT ITC for Commercial Solar Projects
A commercial solar installation with a capital cost of $500,000 generates a $150,000 refundable tax credit under the CT ITC — paid out even if the company has no current tax liability. This makes the CT ITC one of the most valuable tools available for commercial rooftop solar in Canada. Work with a tax advisor familiar with the Clean Economy ITC rules when structuring commercial solar projects.

Licensing and Permitting
Electrical Contractor Licensing
Every province requires solar PV installations to be performed by a licensed electrical contractor. Licensing is administered by the provincial electrical safety authority or an equivalent body.
| Province | Licensing Body | Contractor Requirement |
|---|---|---|
| British Columbia | Technical Safety BC | Registered Electrical Contractor |
| Alberta | Safety Codes Council | Electrical Contractor license |
| Saskatchewan | Saskatchewan Apprenticeship & Trade Certification | Licensed electrical contractor |
| Manitoba | Apprenticeship Manitoba | Master Electrician supervision |
| Ontario | Electrical Safety Authority | Licensed Electrical Contractor |
| Quebec | Régie du bâtiment du Québec | Contractor license C-16 (electrical) |
| New Brunswick | Service New Brunswick | Licensed Electrical Contractor |
| Nova Scotia | Nova Scotia Department of Labour | Licensed Master Electrician |
| PEI | Island Regulatory and Appeals Commission | Licensed Electrical Contractor |
| Newfoundland & Labrador | Service NL | Licensed Contractor |
Contractor license requirements typically include: a licensed Master Electrician on staff or as the supervising electrician, liability insurance, and registration with the provincial authority. Some provinces require additional endorsements or certifications for PV-specific work.
Electrical Permits — Universal Requirement
An electrical permit is required in all provinces before solar installation begins. The permit application is submitted to the provincial safety authority or, in some municipalities, to the local building authority. Required documentation typically includes:
- A single-line diagram of the PV system
- Equipment specifications (inverter, modules, combiner, disconnect)
- Site plan showing panel and inverter locations
- Conductor sizing calculations
- Proof of contractor license
Work cannot begin until the permit is issued. Inspection is required after installation is complete. The system must not be energised before passing inspection.
Inspection Bodies
Inspections are conducted by the provincial electrical safety authority in most provinces. In Ontario, ESA inspectors conduct all electrical inspections. In BC, Technical Safety BC. In Quebec, the RBQ or its authorised inspection agencies. Some municipalities have their own electrical inspection departments that supplement provincial inspection.
The inspection verifies compliance with the applicable CEC edition and local amendments, correct conductor sizing, proper labelling, and safe installation of all system components. A completed inspection results in a Certificate of Electrical Inspection (or provincial equivalent), which the utility typically requires before processing the net metering application.

Step-by-Step: Going Solar in Canada
Confirm your provincial net metering program eligibility
Check directly with your utility for the current program rules: capacity limits, credit rates, application requirements, and whether pre-approval is needed before purchasing equipment. Rules changed in several provinces in 2025–2026. BC Hydro is transitioning to a new Self-Generation Service Rate on July 1, 2026, which affects both credit rates and eligibility conditions. SaskPower’s export rate is locked at 7.5¢/kWh until March 2029. Hydro-Québec expanded to 1 MW in early 2026. Confirm the current state before committing to a system size or contract.
Engage a licensed solar designer and size the system correctly
System sizing in Canada must account for provincial credit carryover rules, not just annual generation totals. Ontario’s 12-month credit expiry, Quebec’s 24-month reset, and Manitoba’s below-retail export rate all affect the optimal system size differently. A system designed for Ontario at 110% of annual consumption may be correctly sized; the same sizing approach applied in Manitoba or Saskatchewan, where export is credited at far below retail, will produce poor economics. Use solar design software that applies province-specific financial models to the sizing calculation. Link your design to the generation and financial tool to model payback under each province’s actual credit and rate structure.
Obtain an electrical permit before installation
Apply to your provincial electrical safety authority (ESA in Ontario, Technical Safety BC, RBQ in Quebec, Safety Codes Council in Alberta, etc.) for an electrical permit. Submit a complete package: single-line diagram, equipment specifications, site plan, and contractor license number. Do not sign a contract with an installer who starts work without a permit in place — unpermitted installations cannot be inspected, cannot receive utility interconnection, and will void most equipment warranties. Permit processing typically takes 1–5 business days for straightforward residential systems.
Submit the utility interconnection application
Most Canadian utilities require a separate interconnection application alongside or prior to installation. BC Hydro and Hydro-Québec require pre-approval of the interconnection agreement before installation begins. Hydro One in Ontario processes a Generation Connection Agreement that includes technical review and bidirectional meter installation. The application package typically includes: system single-line diagram, inverter specifications and certification, contractor details, and, for larger systems, protection coordination studies. Processing times range from 2 weeks for small residential systems to several months for systems above 50 kW. For solar designing and permitting across multiple provinces, a software platform that generates CSA-compliant documentation speeds this process considerably.
Pass electrical inspection and receive permission to operate
After installation, notify the provincial safety authority to schedule an inspection. The inspector verifies compliance with CSA C22.1:24 Section 64, correct labelling, proper disconnect installation, and safe wiring throughout. A Certificate of Electrical Inspection (or provincial equivalent) is issued on passing. Submit this certificate to your utility with the completed as-built documentation. The utility installs the bidirectional meter and issues written permission to operate. Do not energise the system before this written approval — energising without permission breaches the interconnection agreement and can result in disconnection.
Common Compliance Mistakes in Canada
| Mistake | Consequence | Correct Approach |
|---|---|---|
| Installing without an electrical permit | Illegal installation; cannot be inspected; utility will not connect; potential fines | Apply for the permit before any work begins |
| Oversizing for export in Manitoba or Saskatchewan | Poor payback — export credits are well below retail rate | Size to match annual self-consumption; model economics using actual export credit rates |
| Ignoring BC Hydro’s July 2026 rate transition | New customers after July 1, 2026 receive 10¢/kWh export rather than full retail kWh credit | Confirm which rate schedule applies to your project based on installation date |
| Using uncertified inverters | Equipment will fail inspection; utility will not approve interconnection | Verify CSA or SCC-accredited certification mark on all electrical components |
| Applying for Ontario HRSP rebate while planning net metering | HRSP requires load displacement operation — net metering disqualifies the rebate | Choose between HRSP rebate and net metering before committing to either |
| Starting installation before utility pre-approval in Quebec | Hydro-Québec requires pre-approval of connection agreement before installation | Submit interconnection application first; wait for Hydro-Québec approval |
| Forgetting the 24-month credit reset in Quebec | Credits older than 24 months are paid out at supply cost rate and bank zeros | Size system to consume credits within 24 months; track bank balance |
| Unlicensed contractor doing the work | Illegal under CEC and provincial regulations; inspection failure; insurance void | Verify contractor license with the provincial authority before signing any agreement |
| Claiming CT ITC for a residential homeowner | CT ITC is for taxable corporations only — residential homeowners are not eligible | Only taxable Canadian corporations can claim the 30% CT ITC |

Frequently Asked Questions
Is there a federal solar rebate in Canada in 2026?
No federal rebate exists for residential homeowners in 2026. The Canada Greener Homes Grant closed to new applicants in March 2024, having issued nearly $1.8 billion to over 500,000 homeowners. The Canada Greener Homes Loan program stopped accepting applications on October 1, 2025, after issuing over $2.9 billion in interest-free loans.
Businesses can claim the federal Clean Technology Investment Tax Credit — a refundable 30% tax credit on eligible solar PV system capital costs — through December 31, 2033. This applies to taxable Canadian corporations, including Canadian-Controlled Private Corporations (CCPCs).
NRCan has announced plans for a Greener Homes Affordability Program targeting low-to-median income households in 2026, but program structure and funding had not been confirmed as of April 2026. Provincial programs remain the primary incentive avenue for residential homeowners: BC Hydro rebates up to $10,000, Ontario’s HRSP up to $5,000 for solar, PEI’s $1,000/kW rebate up to $10,000, Hydro-Québec’s $1,000/kW grant, and Manitoba Hydro’s $0.50/W rebate are all active.
What is the maximum solar system size for net metering in Canada?
Limits vary by province. British Columbia allows systems up to 100 kW nameplate capacity (with BCUC-approved changes shifting toward net injection limits from July 2026). Ontario allows systems up to 500 kW under O. Reg. 541/05. Hydro-Québec expanded its program cap from 50 kW to 1 MW in early 2026, making large commercial rooftop systems viable in Quebec for the first time.
Alberta’s Micro-generation Regulation allows up to 5 MW — by far the most permissive province for larger commercial and industrial systems. SaskPower, Manitoba Hydro, and most Atlantic utilities cap at 100 kW. Nova Scotia Power has a tiered system: self-generating option up to 27 kW for residential, commercial net metering from 27 kW up to 1,000 kW.
Do I need an electrician to install solar panels in Canada?
Yes, in all provinces. Solar PV systems fall under Section 64 of the Canadian Electrical Code (CSA C22.1:24), which requires installation by or under the supervision of a licensed electrical contractor. Each province licenses electrical contractors through its own authority — ESA in Ontario, Technical Safety BC, RBQ in Quebec, and Safety Codes Council in Alberta.
An electrical permit must be obtained before installation begins, and the completed installation must pass inspection by the provincial safety authority before the system is energised. Unlicensed installation prevents utility interconnection, voids equipment warranties, creates insurance exposure, and may attract fines from the provincial authority.
Which Canadian provinces have the best solar net metering policies?
Alberta offers the highest capacity limit (up to 5 MW) and retail-rate credits negotiated with your electricity retailer, plus high baseline electricity rates that improve solar ROI. Ontario provides reliable 1:1 retail-rate net metering for systems up to 500 kW with a 12-month carryover, backed by the most established solar market in Canada.
Prince Edward Island combines a $1,000/kW rebate (capped at $10,000 residential) with 100 kW retail-rate net metering — strong economics for the province’s scale. Quebec expanded to 1 MW capacity and launched a $1,000/kW grant in April 2026, making it increasingly attractive for commercial rooftop solar. BC Hydro’s program is transitioning to a 10¢/kWh flat export rate from July 2026 — less favourable for export-heavy designs but still viable with high self-consumption ratios.
Manitoba and Saskatchewan both compensate exports at below-retail rates (net billing at $0.04390/kWh and net metering at 7.5¢/kWh respectively), which reduces the economic case for solar relative to other provinces, despite both offering rebate programs.
What electrical code applies to solar installations in Canada?
The Canadian Electrical Code, Part I (CSA C22.1:24, 26th Edition, published 2024) is the national technical standard. Section 64 covers renewable energy systems including solar PV, energy storage, and hybrid AC/DC systems. The 2024 edition introduced a new residential subsection within Section 64, updated DC arc-fault protection requirements, and refined energy storage rules.
The CEC is adopted by each province with local amendments. The enforcing authority varies: the Electrical Safety Authority (ESA) in Ontario, Technical Safety BC, the Régie du bâtiment du Québec (RBQ) in Quebec, the Safety Codes Council in Alberta. Confirm with the provincial authority which edition of the CEC is currently in force in your province and whether any local amendments affect solar PV design before finalising documentation for permit submission.
A well-configured solar software platform generates CSA-compliant single-line diagrams and documentation packages that align with the CEC requirements, reducing the back-and-forth with electrical authorities during permit review.
