Many Canadian businesses leave funding on the table because they assume you can only use one grant or tax credit at a time. In reality, most programs allow grant stacking—as long as you follow specific rules. Knowing how stacking multiple grants and tax credits works in Canada can significantly lower your out-of-pocket costs for hiring, R&D, and growth projects.
Grant stacking is common across federal and provincial programs, but each funder sets limits on how much government support you can receive for the same expense. The key is understanding what can be combined, what must be disclosed, and where businesses often make mistakes.
Grant stacking means using more than one government incentive to fund the same project. These incentives usually fall into two categories:
Most programs allow stacking, but they cap the total government assistance you can receive.
Almost every Canadian grant includes a clause like this:
Total government assistance cannot exceed X% of eligible project costs.
Typical caps include:
If your project costs $100,000 and the stacking limit is 75%, the combined value of all grants and tax credits cannot exceed $75,000.
GrantHub’s eligibility matcher helps you filter programs by province and industry and see which grants can be stacked with tax credits, making planning easier.
Understanding the difference between grants and tax credits is essential when stacking.
A common example is combining innovation grants with the Scientific Research and Experimental Development (SR&ED) Tax Incentive Program.
The SR&ED program is a federal tax incentive administered by the Canada Revenue Agency (CRA). It supports eligible R&D work through investment tax credits.
Key stacking considerations:
Here are practical ways Canadian businesses stack funding legally.
Many provinces allow their funding to stack with federal programs, provided you stay under the total assistance cap.
Wage subsidies often stack with project grants, but:
This is one of the most common combinations for R&D-heavy businesses:
GrantHub’s database helps you find active programs that can be combined, so you can maximize your funding.
Disclosure is not optional. You must report:
Failing to disclose stacking can lead to:
Tax credits like SR&ED are considered government assistance and must be included in stacking calculations. Omitting them can trigger audits.
You cannot be reimbursed twice for the same dollar of cost. Funders cross-check expenses during reporting.
Many businesses focus on the grant amount and miss the total funding limit buried in program guidelines.
If you receive additional funding after approval, you are required to notify the original funder.
Q: Can I stack multiple federal grants together?
Yes, but most federal programs cap total government assistance. You must disclose all federal funding sources and stay under the maximum percentage allowed.
Q: Does SR&ED stack with provincial R&D credits?
Yes. Federal SR&ED can stack with provincial R&D tax credits, but both are reduced by any grants received for the same work.
Q: Can I apply for multiple grants at the same time?
Yes. Applying in parallel is allowed, as long as you disclose all applications and approvals.
Q: What happens if I exceed the stacking limit?
The funder will usually reduce their contribution or require repayment of excess funds.
Q: Do loans count toward stacking limits?
Most repayable loans do not count as government assistance, but some partially forgivable loans do. Always confirm with the program guidelines.
Stacking multiple grants and tax credits works best when you plan early and track every dollar of assistance tied to your project. GrantHub tracks hundreds of active grant programs across Canada and shows which ones can stack—before you apply—so you can fund more of your business with confidence.
