Many Canadian businesses qualify for more than one government grant. The challenge is combining them without breaking stacking rules—the limits on how much public funding you can receive for the same project costs. If you get it wrong, you risk clawbacks or denied claims. If you get it right, you can fund more of your project legally and confidently.
Stacking rules set a cap on the total government assistance you can receive for the same eligible costs. The cap is usually a percentage of your project costs. This includes funding from federal, provincial, territorial, and sometimes municipal sources.
Common stacking caps include:
Each program defines:
Read the stacking section of each program carefully. If you are unsure, disclose everything.
Stacking problems often happen when two programs pay for the same line item. Make a simple budget that splits costs, such as:
You can usually fund different cost categories with different programs, even if they support the same project.
Look for rules like “total government assistance cannot exceed X% of eligible costs.”
For example:
Tax credits such as SR&ED are treated differently:
Many R&D-focused businesses make mistakes here.
You must disclose all government funding at both the application and reporting stages. This includes:
Not disclosing can trigger audits or repayment, even if you stayed under the cap.
Some programs offer advisory services instead of cash. For example, NRC IRAP Advisory Services provide technical and business advice at no cost and do not count as direct project funding. This support can complement cash grants without affecting stacking.
Tools like GrantHub’s eligibility matcher help you filter programs by province and industry in seconds, making it easier to find combinations that usually work together.
This is allowed, as long as you exclude grant-funded expenses from your SR&ED claim.
Advisory services don’t increase your stacking total, so this combination is usually compliant.
Funding the same invoice with two programs
Never claim the same cost twice, even if both approvals come through.
Forgetting that tax credits count as government assistance
SR&ED and provincial R&D credits affect stacking calculations.
Assuming programs don’t share information
Funders often share information with each other.
Not updating funders when new support is approved
You must report changes, even after your project starts.
Q: Can I combine federal and provincial grants for the same project?
Yes, as long as the combined government funding stays within the stacking cap and you don’t claim the same costs twice.
Q: Does SR&ED count as stacking with grants?
Yes. SR&ED is government assistance and usually reduces your eligible SR&ED expenditures if you also received grants for the same work.
Q: What happens if I exceed a stacking limit?
The funder may reduce your contribution or require repayment of the excess amount.
Q: Do advisory programs affect stacking?
Non-cash advisory services, like NRC IRAP Advisory Services, generally do not count toward stacking limits because no project funds are paid out.
Q: Should I apply for multiple grants at the same time?
You can, but disclose all applications and plan your budget so each program funds different costs.
Combining grants takes careful planning, clear budgeting, and honest reporting. When you understand stacking rules before you start, you can fund more of your project without risking clawbacks.
