Grant stacking in Canada: how to combine federal and provincial funding legally

Many Canadian business owners think you can only get one grant per project. That’s not always true. Grant stacking in Canada—using more than one government funding program for the same project—is often allowed if you follow the rules. If you do it right, combining federal and provincial funding can lower your costs. But you must respect each program’s funding limits and be open about all your sources, or you could risk having to pay money back or face an audit.


How grant stacking works in Canada

Grant stacking means using more than one government funding program for the same project. This can include federal grants, provincial grants, tax credits, and wage subsidies.

The main concern is not how many programs you use, but how much of your project’s costs are covered by public funding.

The key rule: stacking limits

Most Canadian grant programs set a maximum percentage of public funding—called a stacking limit. For example:

  • 75% of eligible project costs is a common limit for many innovation and commercialization programs, such as the Industrial Research Assistance Program (IRAP) and the Alberta Innovates Voucher Program. Always check the guidelines for each program, as limits can vary.
  • 90–100% for certain non-profit or research-led projects, like those funded by the Social Sciences and Humanities Research Council (SSHRC).
  • Some for-profit programs have lower limits, especially if you are stacking multiple wage subsidies.

Stacking limits usually include:

  • Federal grants and contributions
  • Provincial and territorial grants
  • Municipal funding
  • Refundable tax credits

Private investment and bank loans do not count toward stacking limits.

Disclaimer: Stacking limits are set by each program and can differ. Always read the program guidelines for the exact rules.


Federal and provincial funding can usually be combined

In most cases, you can combine federal and provincial grants, as long as you stay within the total funding cap.

For example:

  • A provincial innovation grant covers 40% of your project’s costs
  • A federal R&D program covers 35%
  • Your business pays the remaining 25%

This is a typical and legal approach when you disclose all funding sources to each program.

How tax credits fit into grant stacking

Tax credits are handled differently from direct grants, but they often count as government assistance.

Example: SR&ED and grant stacking

The Scientific Research and Experimental Development (SR&ED) Tax Incentive Program is a federal program from the Canada Revenue Agency.

Key facts:

  • Supports eligible R&D done in Canada
  • Offers investment tax credits of up to 35% on qualifying costs for Canadian-controlled private corporations (CCPCs)
  • Open to corporations, individuals, and partnerships

If you receive a grant for the same R&D costs:

  • The grant amount usually reduces the SR&ED-eligible expenditures
  • You must report all government assistance in your SR&ED claim

SR&ED can be stacked with grants, but you cannot claim both for the same dollar amount without making adjustments.


What you must disclose when stacking grants

Transparency is required. Nearly every funding agreement asks you to declare:

  • All approved and pending government funding
  • The same project costs claimed across programs
  • Any changes to your funding sources after approval

If you do not disclose stacking, you could face:

  • Repayment demands
  • Loss of future eligibility
  • Compliance reviews

GrantHub tracks active grant programs across Canada, making it easier to compare stacking rules for your project.


Common mistakes to avoid

1. Exceeding the maximum public funding limit

Even if each program approves your application, you are responsible for staying under the combined cap.

2. Claiming the same expense twice without adjustment

Some programs allow overlapping costs, but others require you to reduce the amount claimed. Always check the contribution agreement.

3. Forgetting to update funders

If you get new funding after approval, most programs require you to tell them within a certain time.

4. Assuming tax credits don’t count

Refundable tax credits like SR&ED are often considered government assistance and must be disclosed.


Frequently Asked Questions

Q: Is grant stacking legal in Canada?
Yes. Grant stacking is legal if you follow each program’s funding limits and disclosure rules. Most federal and provincial programs have clear stacking policies.

Q: Can I stack two federal grants together?
Sometimes. It depends on the programs and whether they fund the same costs. Some federal programs do not allow stacking with other federal sources.

Q: Do provincial grants affect my SR&ED claim?
Yes. Provincial grants for the same R&D work usually reduce the expenditures eligible for SR&ED credits.

Q: What happens if I exceed the stacking limit?
You may have to repay the extra funding. In serious cases, future applications can be rejected or flagged for review.

Q: Are loans included in stacking calculations?
Usually no. Repayable loans and private financing are not considered government assistance, but always check each program’s guidelines.


Tips for planning your grant stacking strategy

  • Read all program guidelines carefully: Stacking rules can change between programs and years.
  • Map out your project costs: Know which expenses you want to cover and which programs can fund them.
  • Keep a record of all funding sources: This helps with reporting and avoids mistakes.
  • Check for updates: Funding rules can change, so review them before each application.
  • Use tools like GrantHub: These can help you compare programs and stacking limits quickly.
