Canada’s 30% Solar Tax Credit 2026: Contractor Guide

Key Takeaway: Canada’s Clean Technology ITC provides a refundable 30% federal tax credit on commercial solar installations for taxable Canadian corporations. As of April 2026, there is no domestic content requirement: all eligible equipment qualifies regardless of manufacturing origin. A Finance Canada consultation (February 13 to March 13, 2026) is considering adding one. Projects installed in 2026 under the current rules are not retroactively affected by any future change.

Canada’s Clean Technology Investment Tax Credit (CT ITC) has been the most powerful federal solar incentive available to commercial clients in Canada since March 2023: a refundable 30% credit on eligible solar capital costs, no domestic content requirement, stackable with provincial programs. For Ontario contractors, it has been a straightforward part of the close.

That is about to get more nuanced. In February 2026, the federal government opened a consultation on adding domestic content requirements to the CT ITC, meaning panels and components manufactured outside Canada could eventually qualify for a reduced incentive rate or face additional eligibility criteria. The consultation ran from February 13 to March 13, 2026. Policy decisions are expected in the months ahead.

Here is what Ontario contractors and their commercial clients need to understand, and why the window for acting under the current rules is one of the most important near-term opportunities in Ontario commercial solar.

Clients who install solar in 2026 under the current rules lock in the full 30% credit, regardless of what the domestic content consultation ultimately decides.

What the CT ITC Currently Covers, As of April 2026

The Clean Technology ITC was introduced in Canada’s 2022 federal budget, legislated in 2023, and applies retroactively to eligible equipment placed in service from March 28, 2023. The current terms:

The ‘refundable’ designation matters. This is not a deduction that reduces taxable income: it is a credit that directly offsets taxes owing. If the credit exceeds the corporation’s tax bill in the year, CRA issues a refund cheque for the difference. For a corporation with low taxable income in a given year, the credit is still fully recoverable.

On a $500,000 commercial solar installation: the CT ITC generates a $150,000 refundable federal credit. CRA either applies it against taxes owing or sends the cheque. The full $150,000 is received either way.

What the Domestic Content Consultation Proposes

On February 13, 2026, Finance Canada launched a formal consultation on whether to require eligible equipment to contain a minimum percentage of Canadian-manufactured content to receive the full 30% CT ITC rate. The consultation closed March 13, 2026. It asked five core questions:

The proposed policy mirrors the domestic content bonus structure in the U.S. Inflation Reduction Act. The most widely used commercial solar panels in Canada in 2026 are manufactured primarily in China, Vietnam, and Malaysia. If a domestic content requirement applies to PV modules, those panels may qualify for a reduced credit rate unless they meet Canadian content thresholds, which given the current state of Canadian solar panel manufacturing would be difficult for most projects to satisfy in the near term.

Why Timing Is Critical for Every Client Conversation

The current CT ITC has no domestic content requirement. Any eligible solar equipment, regardless of country of manufacture, qualifies for the full 30% credit today.

Projects that are installed and commissioned in 2026 under the current rules claim the 30% credit on their 2026 tax return, based on the law as it stood when the equipment was placed in use. A subsequent policy change does not retroactively alter that claim. The risk is entirely on the delay side.

A commercial client who waits until 2027 may face a different incentive structure, depending on what the government decides following the consultation. They may qualify for a reduced rate, face a more complex eligibility test, or need to source specific equipment to maximize the credit.

Policy uncertainty is a sales catalyst. The accurate message to clients is: ‘The rules today are clearer and more favorable than the rules in 2027 will be. Here’s what your building qualifies for right now.’

Solenery’s commercial property intelligence platform pre-calculates the full incentive stack, Save on Energy and federal CT ITC, for every building in its scouted prospect reports. Contractors who use Solenery walk into first calls with a property-specific incentive figure already calculated: not a generic “up to 30%” claim, but a dollar amount specific to that building’s size, system capacity, and eligible costs. That precision is what moves clients from ‘interested’ to ‘proceeding.’ solenery.com.

The Complete Ontario Commercial Solar Incentive Stack in 2026

Contractors who can explain the full incentive picture, not just one piece of it, close more projects. Here is the complete stack for Ontario commercial solar in 2026:

1. Federal Clean Technology ITC: 30% refundable tax credit. Available to taxable Canadian corporations on eligible solar capital costs. No domestic content requirement as of April 2026. Applies to the full installed system cost.

2. Ontario Save on Energy: $860/kW (10 kW AC or larger) or $1,000/kW (under 10 kW DC). Capped at 50% of eligible project costs. Available to commercial, industrial, institutional, and agricultural property owners. Part of a $1.8 billion 2025-2027 program budget.

3. CCA Class 43.2: 100% first-year capital cost allowance. Solar PV systems qualify for accelerated depreciation under Class 43.2, allowing the full capital cost to reduce taxable income in the installation year, independently of the CT ITC.

4. HST input tax credits. GST/HST paid on commercial solar installation is recoverable as an ITC for registered businesses, reducing the effective net cost further.

Example for a 200 kW commercial installation at $400,000 gross:

Note: the Save on Energy incentive is capped at 50% of eligible project costs. Model each project specifically. For the pipeline tool that calculates this for every building in your service area, see Solenery’s commercial property intelligence platform at solenery.com.

How to Use the Policy Conversation to Move Clients Forward

Contractors who understand the policy environment close more projects than those who only talk about panels and watts. The conversation is honest and direct:

“The 30% federal tax credit currently has no domestic content requirement. The government opened a consultation on adding one in early 2026: we’re waiting for the outcome. What we know today is that any project installed under the current rules qualifies for the full 30% credit. Stack that with the Save on Energy incentive and Ontario’s 71% electricity rate increase, and the economics right now are the best they’ve been in Ontario’s solar history. If you wait until 2027, that may still be true, but there’s no guarantee the incentive structure will be as clean.”

That is not manufactured urgency. That is an accurate description of the policy environment. Contractors who can deliver it with confidence, and back it up with property-specific numbers, are the advisors commercial clients trust.

Solenery’s platform gives contractors the property-specific numbers that make this conversation credible. Each scouted building in Solenery’s prospect reports has its Save on Energy incentive and federal CT ITC pre-calculated, so when a contractor says ‘here’s what your building qualifies for,’ they’re citing a specific dollar figure for that specific address, not a range. The Green Snapshot™ report formalizes this into a professional leave-behind. Contractors in Solenery’s first pilot cohort (15 spots, first month free) get this for every property in their service area. solenery.com.

Frequently Asked Questions

What is Canada’s Clean Technology Investment Tax Credit for solar in 2026?

The Clean Technology ITC is a refundable 30% federal tax credit on the capital cost of eligible clean technology property, including solar PV systems, for taxable Canadian corporations. It applies to new equipment placed in service from March 28, 2023 through December 31, 2034. The credit is refundable: it applies against taxes owing or is paid out as a refund if it exceeds the tax bill.

What is the domestic content consultation for the Clean Technology ITC in Canada?

Finance Canada opened a consultation on February 13, 2026 seeking input on whether to add a domestic content requirement to the CT ITC. The consultation closed March 13, 2026. If implemented, qualifying for the full 30% rate would require a percentage of eligible equipment to be Canadian-manufactured. No final decision has been published as of April 2026. Projects installed in 2026 under current rules are not retroactively affected.

How do I claim the 30% Clean Technology ITC for a commercial client in Canada?

The CT ITC is claimed on a corporation’s T2 corporate income tax return for the year in which eligible equipment is ‘available for use’ (installed and operational), on Schedule 31. For refundable amounts exceeding taxes owing, CRA processes and issues the refund. Retain equipment specifications, installation costs, commissioning dates, and supplier invoices. Advise clients to work with a CPA familiar with clean economy ITCs for the filing.

Can a commercial client stack the CT ITC with Ontario’s Save on Energy program?

Yes. The federal CT ITC and Ontario’s Save on Energy program are stackable on the same installation. The Save on Energy incentive reduces the eligible project cost for ITC calculation purposes, so the 30% credit applies to the net cost after the grant. Model each project specifically, as the Save on Energy cap (50% of eligible cost) interacts with the ITC base in ways that vary by project size.

Does the federal solar tax credit apply to solar panels made in China in 2026?

Yes, as of April 2026. The CT ITC has no domestic content requirement: eligible equipment qualifies for the full 30% credit regardless of country of manufacture. A federal consultation (February to March 2026) is considering adding a domestic content requirement for future years. Projects installed and commissioned in 2026 under current rules are protected at the full 30% rate.
