Many Canadian businesses qualify for more than one government grant at the same time. The challenge is not finding funding — it’s making sure you combine grants legally and don’t trigger clawbacks later. The key issue is “stacking rules,” which limit how much total public funding you can receive for the same costs.
This guide explains how combining multiple government grants works in Canada, what funders look for, and how to stay compliant from application to audit.
“Grant stacking” means using more than one government funding program to support your business. Stacking is usually allowed, but only within strict limits.
Here’s how funders typically assess compliance:
Most Canadian grants limit how much public funding you can receive toward the same project or expense. Public funding includes:
A common cap is up to 75% of eligible project costs, but the exact percentage depends on the program. Some programs cap funding at 50%, while others allow higher support for nonprofits or Indigenous-owned businesses.
You can’t use two grants to pay for the same dollar of cost. For example:
This is the most common reason businesses fail compliance reviews.
Almost all grant applications ask you to declare other funding sources, including:
Failing to disclose other funding is considered misrepresentation, even if the total funding would have been allowed.
Tools such as GrantHub’s eligibility matcher can help you filter programs by province and industry in seconds and flag where stacking limits may apply.
Before combining grants, it’s important to check the stacking rules for each program you’re considering. Stacking rules are usually found in:
If you’re unsure, contact the program administrator directly. They can clarify whether your planned funding combination is allowed, and what documentation you’ll need. Some grant advisors or consultants can also help interpret stacking rules for complex projects.
Combining grants works best when each program supports a different part of your business activity.
You might structure funding like this:
As long as costs don’t overlap, stacking is usually permitted.
If you’re running multiple initiatives, treat them as distinct projects with:
Funders are more comfortable approving stacked funding when projects are clearly defined and documented.
Keep organized records from day one:
This documentation matters if you’re audited — sometimes years later.
If your funding plan involves several grants or complex cost-sharing, consider consulting a grant advisor. Advisors can:
Some businesses use GrantHub’s database to compare stacking limits and find programs that fit their needs. For more complicated projects, a grant advisor can help you avoid mistakes that might lead to clawbacks or funding denials.
Even non-repayable grants count toward stacking limits. Always check total public funding caps.
Refundable tax credits are often considered government assistance. If you don’t disclose them, you may exceed allowed limits.
If your project changes after approval, stacking rules may change too. Get written confirmation before reallocating costs.
Problems are harder to fix after the money is spent. Review stacking limits before submitting claims.
Q: Is it legal to combine federal and provincial grants?
Yes. Federal and provincial grants can usually be combined, as long as you stay within total public funding limits and don’t double-fund expenses.
Q: Can I combine grants with loans or private investment?
Yes. Private investment and commercial loans generally do not count toward public funding caps.
Q: What happens if I exceed a stacking limit?
The funder may reduce your reimbursement, require repayment, or deny future claims. In serious cases, it can affect eligibility for future programs.
Q: Do I need approval before applying to another grant?
Often yes. Many programs require written disclosure or approval if you apply for additional funding covering the same project.
Q: Are wage subsidies treated differently than project grants?
Sometimes. Wage subsidies often have their own limits and may interact differently with other programs, especially if they support the same employees.
Combining multiple government grants is possible — and common — when you plan costs carefully and disclose everything upfront. The safest approach is to understand stacking limits before you apply, not after you spend.
