Grant stacking lets you combine funding from different levels of government to cover more of your project costs. If you do it right, you could get tens of thousands more in non-repayable support. If you do it wrong, you might have to pay money back or lose your grant. The key is understanding how Canadian funders define stacking and where the limits apply.
Across Canada, most public funders allow some level of stacking, but nearly all set a maximum government assistance cap, often between 75% and 100% of eligible project costs.
Grant stacking means using municipal, provincial, and federal funding for the same project without exceeding program limits or double-counting expenses.
Here’s how governments typically look at it:
Most programs ask the same core question:
What percentage of total eligible costs is paid for by government sources?
These caps apply to all government funding combined, not per program.
The Scientific Research and Experimental Development (SR&ED) Tax Incentive Program allows businesses to earn refundable or non‑refundable tax credits for eligible R&D work.
Important stacking rule:
This means SR&ED stacks best with:
Some programs look like grants but are actually financing.
For example, the Canada Digital Adoption Program (CDAP) Loan, delivered by BDC, provides up to $100,000 in financing with 0% interest for the first year to support digital transformation.
Why this matters:
However, the CDAP Loan is not a grant, so it won’t reduce your total project cost the same way non‑repayable funding does.
Many provinces expect municipalities to co‑fund projects.
Typical pattern:
This structure is usually encouraged, but you must disclose every source during application. Tools like GrantHub’s eligibility matcher can help you filter programs by province and industry in seconds.
When reviewing stacked funding, assessors focus on three things:
Total government assistance
All grants, subsidies, and forgiven loans are added together.
Eligible vs. ineligible costs
Marketing, internal labour, or capital purchases may be excluded depending on the program.
Timing of approvals
Some grants prohibit stacking with funding approved after their own approval date.
Always read the “stacking” or “government assistance” section in the program guide. If it’s missing, assume disclosure is mandatory.
Hiding other funding sources
Funders routinely cross‑check disclosures. Undeclared grants can lead to repayment demands.
Using two grants for the same invoice
You cannot claim 100% reimbursement for a single expense unless explicitly allowed.
Assuming loans don’t count without checking
Some “conditionally repayable” contributions are treated like grants until repaid.
Applying in the wrong order
Certain programs require confirmation of other funding first, while others forbid retroactive stacking.
Q: Can I stack municipal, provincial, and federal grants together?
Yes, in many cases. You must stay within the maximum government assistance limit set by each program and disclose all sources.
Q: Does SR&ED count as government funding when stacking grants?
Yes. SR&ED tax credits reduce eligible R&D expenditures and must be factored into your total government assistance.
Q: Are government loans included in stacking limits?
Usually no, if they are fully repayable. Partially forgivable loans may count until repaid.
Q: What happens if I exceed the stacking cap?
The funder may reduce your grant amount or require repayment after audit.
Q: Can I stack grants from different provinces?
Only if your project has eligible activities in each province and both programs explicitly allow it.
GrantHub tracks hundreds of active grant programs across Canada — check which ones match your business profile.
Grant stacking works best when planned early, before you apply. Map your project costs, identify which expenses fit each program, and confirm stacking rules in writing. See also:
Understanding eligibility upfront saves time, protects your funding, and helps you get the most public support possible for your business.
