Grant stacking might seem straightforward: apply to more than one program to cover your project costs. In reality, it’s one of the fastest ways to get rejected if you miss the details. Many Canadian grant programs do allow stacking. However, each funding body sets strict rules you must follow.
This guide explains the most frequent grant stacking mistakes and how to avoid them before they cost your business time, credibility, and funding. GrantHub’s eligibility matcher can help you check stacking rules and avoid common pitfalls right from the start.
Grant stacking means using more than one government funding program to pay for the same project. This can include federal, provincial, municipal, or Crown corporation funding.
Most Canadian grants allow stacking, but only up to a maximum public funding limit. This is usually shown as a percentage of total eligible project costs. The main rule is clear:
You cannot be reimbursed more than 100% of eligible costs. Many programs set the cap well below that.
Typical stacking scenarios:
This is the most common reason for rejection.
Many programs cap total government support at 50%, 75%, or 100% of eligible costs. If your combined funding goes over that cap, one or more of your applications could be denied.
Where things go wrong:
Even if each application looks fine on its own, together they can break the rules.
Most applications ask if you’ve applied for or received other funding.
Common mistakes:
Funding agencies often share information. Not disclosing other funding is usually seen as misrepresentation, which can lead to rejection or future ineligibility.
Even if stacking is allowed, claiming the same cost twice is not.
Examples that cause problems:
Most programs require that each dollar is claimed only once. You must clearly assign costs to specific funding sources.

Q: Is grant stacking allowed in Canada?
Yes, many Canadian grant programs allow stacking. However, it’s usually capped and tightly regulated. You must follow each program’s specific stacking rules.
Q: Do I need to disclose funding I’ve only applied for?
Yes. Most programs require you to disclose both approved and pending funding. Omitting this information can lead to rejection.
Q: Can I stack federal and provincial grants together?
Sometimes. It depends on the programs and the total public funding limit. Always check both program guidelines.
Q: What happens if I exceed the stacking limit after approval?
The funding body may reduce your grant, delay payment, or require repayment. In serious cases, it can affect future eligibility.
Q: Are loans treated differently than grants for stacking?
Often, yes. Repayable contributions and loans may be treated separately, but they can still count toward total government assistance.
