Many Canadian business owners ask the same question before applying for grants: Can I combine more than one government program to fund the same project? The short answer is yes—but only up to a limit. Grant stacking rules in Canada set clear caps on how much public funding you can receive for one project. If you go over that limit, you may face clawbacks or lose eligibility.
No similar education article is available in GrantHub’s library on this exact topic. This guide explains the rules that apply across federal, provincial, and municipal programs. It does not focus on one specific grant but covers stacking rules that affect most applicants.
Grant stacking means using more than one source of government support to pay for the same eligible project costs. These sources can include:
Most Canadian programs allow stacking, but they set a maximum total government assistance (TGA) limit. This limit is usually shown as a percentage of eligible project costs.
Across Canada, you will typically see one of these caps written directly into program guidelines or contribution agreements:
If your project costs $200,000 and the stacking limit is 50%, the total of all government funding combined cannot exceed $100,000. This includes funding you have already received or expect to receive later.
A common source of confusion is what actually counts as government assistance.
In most Canadian programs, stacking calculations include:
In many cases, they also include:
Some programs exclude:
Definitions can vary. Always check the program’s “stacking” or “total government assistance” section. Tools like GrantHub’s eligibility matcher help you filter programs by province and industry, making it easier to compare stacking language before you apply.
Grant stacking rules apply across levels of government, not separately.
That means:
For example, if a federal program allows up to 50% stacking and you already received 30% from a province, the federal portion is usually capped at the remaining 20%.
Stacking is not just checked at the application stage.
Most programs require you to:
If total government assistance exceeds the allowed limit, funders may:
Transparency matters. Failing to disclose another grant is one of the fastest ways to lose funding.
Assuming tax credits do not count
Many refundable tax credits are included in stacking calculations. Always confirm in writing.
Applying for multiple grants without checking the combined cap
Each program may look generous on its own, but together they may exceed the limit.
Forgetting to update funders after approval
Receiving new funding after signing an agreement can still affect stacking compliance.
Mixing project costs incorrectly
Stacking applies only to the same eligible costs. Separate projects may have separate limits if clearly defined.
Q: Can I use more than one grant for the same project in Canada?
Yes. Most programs allow grant stacking, but only up to a maximum percentage of eligible costs. This limit is set by the program and enforced across all government funding.
Q: Is there a universal stacking limit in Canada?
No. While 50% and 75% are common, stacking limits vary by program type, applicant type, and sector.
Q: Do provincial and federal grants count together?
Yes. Stacking limits apply to total government assistance, regardless of the level of government.
Q: What happens if I exceed the stacking limit?
The funder may reduce their contribution or require repayment of the excess amount. In serious cases, it can affect future eligibility.
Q: Can different projects have different stacking limits?
Yes. Each approved project is assessed separately, as long as costs are clearly separated and documented.
Grant stacking rules are manageable once you know the limits, but they can be tricky if you apply for several programs at once. Sign up for GrantHub to easily compare stacking rules across Canadian programs and see how funding sources fit together before you apply. This helps you stay within limits and disclose with confidence.
