Energy costs are one of the fastest-growing operating expenses for commercial buildings in Canada. Governments are responding with clean energy and building efficiency grants that help offset the cost of retrofits, fuel switching, and low-carbon heating systems. For property owners and facility managers, understanding these programs is essential. Knowing the details can help you decide whether to delay a project or move ahead this year.
Clean energy and building efficiency grants for commercial buildings usually follow a similar structure, though funding amounts and rules vary by province and program.
Most programs focus on three outcomes:
For commercial applicants, funding is typically tied to eligible project costs and paid as a non-repayable contribution or rebate once milestones are met. Some programs also combine grants with low-cost financing.

Below are three real programs that Canadian commercial and institutional building owners should understand. Each works differently and targets a specific part of the clean energy transition.
This Quebec-only program supports partial conversion of natural gas heating systems to bi-energy systems that use both electricity and natural gas. The goal is to reduce emissions while maintaining grid reliability during peak demand.
Key details
Eligible costs may include heating system conversion, electrical upgrades, and professional fees directly tied to the bi-energy project. This program is especially relevant for large commercial buildings with high space-heating loads.
While not a traditional grant, the Building Retrofits Initiative plays a major role in reducing carbon emissions in commercial buildings by offering attractive financing for large retrofit projects.
Key details
BRI financing is often combined with provincial or utility grants to reduce overall project risk and upfront capital requirements.
CMHC Eco Plus offers a 25% refund on CMHC mortgage insurance premiums for energy-efficient, newly built properties. While this program primarily applies to residential and multi-unit housing, it can be relevant for commercial developers working on mixed-use projects with insured residential components. It is not a retrofit grant and does not apply to most stand-alone commercial buildings.
Across Canada, clean energy and building efficiency grants for commercial buildings commonly support:
Programs almost always require pre-approval before construction starts. Costs incurred too early are often deemed ineligible.
Starting construction before approval
Most programs will not reimburse costs incurred before you receive written approval.
Underestimating documentation requirements
Energy models, fuel consumption data, and technical specs are often mandatory for clean energy funding.
Assuming one program covers everything
Large commercial projects usually stack grants, rebates, and financing. Relying on a single program can leave funding gaps.
Missing utility or fuel-supplier rules
Programs like Écoperformance require specific suppliers, such as Énergir, which can affect eligibility.
Q: Are clean energy and building efficiency grants taxable in Canada?
In many cases, grant funding is considered taxable income. Your accountant should confirm how to treat the funding for your specific project and structure.
Q: Can commercial tenants apply, or does the owner need to apply?
Most programs require the building owner to apply or provide written consent. Tenant-led projects are possible but less common.
Q: How long does approval usually take?
Approval timelines range from a few weeks to several months, depending on project size and technical review requirements.
Q: Can I combine provincial grants with federal programs?
Yes. Stacking is often allowed, as long as total public funding does not exceed program limits. Always disclose all funding sources.
Q: Do I need an energy audit before applying?
Many clean energy and building efficiency grants require an energy study or modelling, especially for larger commercial buildings.
