Many Canadian businesses miss out on available funding because they are unsure whether they can combine funding programs. Others stack grants incorrectly and face clawbacks months later. The good news is that stacking multiple grants and tax credits is allowed in Canada—but only if you follow each program’s rules carefully and disclose all funding sources upfront.
If you follow the rules, stacking grants and tax credits can significantly reduce your out-of-pocket costs. If you do not follow the rules, you may face repayment demands, reduced tax credits, or become ineligible for future funding.
“Stacking” means using more than one public funding program to support the same business or project. This can include:
Stacking is not automatically prohibited. What matters is how each program defines eligible costs and maximum government assistance.
Most Canadian programs apply a maximum stacking limit, often expressed as a percentage of eligible project costs. For example, a program may allow up to 75% or 100% of eligible expenses to be covered by public funding).
If you exceed that limit, the funder can reduce your payment or claw back funds already paid.
One of the most commonly stacked programs is the NRC IRAP Advisory Services program.
NRC IRAP basics:
IRAP funding can often be stacked with:
However, IRAP requires you to declare all other government assistance related to the same project. If combined funding exceeds the allowed limit, IRAP will reduce its contribution—not the other way around.
Using tools like GrantHub’s eligibility matcher can help you filter programs by province, industry, and funding type before you apply, making compliant stacking much easier.
Tax credits are treated differently than grants, but they still count as government assistance in many cases.
Here is the general rule used across federal and provincial programs:
For example, if you receive a grant that covers part of an employee’s wages, you typically cannot claim a tax credit on that same portion of wages.
This is where many clawbacks start—businesses claim the full tax credit without netting out grant-funded costs.
Follow these rules to avoid clawbacks:
If two programs both fund wages, split the costs clearly. If one funds equipment and another funds labour, stacking is usually simpler.
Assuming tax credits don’t count as government funding
They often do. Many programs require tax credits to be included in stacking calculations.
Failing to update funders after approval
Getting new funding later without notifying existing funders can trigger retroactive clawbacks.
Double-claiming the same expense
Claiming the same dollar of wages or equipment under two programs is one of the fastest ways to lose funding.
Ignoring final reconciliation rules
Some programs reassess stacking after your project ends, not when you apply.
Q: Is grant stacking legal in Canada?
Yes. Grant stacking is legal and common, as long as you stay within each program’s stacking limits and disclose all funding sources.
Q: Can you stack grants and tax credits together?
Usually yes, but grant-funded expenses often reduce the amount you can claim for tax credits. Always adjust eligible costs accordingly.
Q: What happens if you exceed a stacking limit?
The funder may reduce future payments or claw back funds already paid. In some cases, it can also affect eligibility for future programs.
Q: Do provincial and federal grants count together?
Yes. Most programs look at total government assistance, not just funding from the same level of government.
Q: When do clawbacks usually happen?
Most clawbacks occur during final reporting, audits, or tax credit reviews—often months after the money is spent.
Stacking grants and tax credits safely is all about planning before you apply, not fixing problems later. GrantHub tracks hundreds of active grant and tax credit programs across Canada. Check which ones match your business profile and see how they can work together without risking clawbacks.
