Many Canadian businesses assume you can only use one government funding program at a time. That’s not true. In most cases, you can combine multiple grants, tax credits, and advisory programs—as long as you respect stacking rules. These rules control how much total government support your project can receive and how costs are shared.
Stacking mistakes are one of the top reasons funding gets reduced or clawed back. Understanding the rules up front helps you plan projects that are fully compliant and fully funded.
Stacking means using more than one government funding program for the same project or costs. Federal, provincial, and municipal funders all apply stacking limits to prevent overfunding.
In plain terms, stacking rules answer three questions:
Most Canadian programs set a maximum government assistance percentage, often between 50% and 75% of eligible project costs, depending on the program and applicant type.
Each program defines its own limits, so you must follow the strictest rule when combining funding.
Not all government support is treated the same. Knowing the difference is key.
These include repayable and non-repayable contributions from federal or provincial programs. They almost always count toward stacking limits.
Tax incentives are often treated differently than upfront grants.
Always check how each program defines “government assistance” before assuming tax credits are exempt.
Some government programs provide non-financial support that does not count toward stacking limits.
For example, NRC IRAP Advisory Services offer technical and business advice at no cost to eligible Canadian SMEs, without direct funding attached. Because no cash changes hands, this type of support typically does not count as government assistance—but it still must be disclosed if asked.
Programs like this are ideal complements to grants that fund wages or R&D expenses.
Here’s a practical, compliant approach used by experienced applicants.
Break your project into cost categories such as:
This lets you assign different costs to different programs instead of stacking everything on the same expense.
Avoid funding the same dollar twice unless explicitly allowed.
Example:
GrantHub’s eligibility matcher can help you filter programs by province, industry, and cost type in seconds, making it easier to plan your funding mix.
If one program caps government funding at 75%, that cap usually applies to all stacked funding combined—even if another program allows more.
When in doubt, assume the lowest cap wins.
Every application will ask about other government support. Missing or inconsistent disclosures are a major red flag and can trigger audits or repayment demands.
1. Funding the same wages with two programs
Most programs prohibit “double-dipping” on the same cost line, especially salaries.
2. Forgetting to disclose advisory or provincial support
Even non-cash or small programs may need to be declared.
3. Assuming tax credits don’t count
Some funders explicitly include tax incentives in stacking calculations.
4. Applying in the wrong order
Certain programs require confirmation of other funding first. Applying out of sequence can make you ineligible.
Q: Can I combine federal and provincial grants for the same project?
Yes, in many cases. The combined funding just can’t exceed the stacking limit set by the programs involved.
Q: Do I need written approval to stack funding?
Often yes. Many funders require formal confirmation once other funding is secured.
Q: What happens if I exceed the stacking limit?
Excess funding is usually reduced or clawed back. In serious cases, future eligibility can be affected.
Q: Does advisory support count as government funding?
Not always. Programs like NRC IRAP Advisory Services provide non-financial support that typically doesn’t count toward stacking, but you should still disclose it.
Q: Can I change my funding mix after approval?
Only with written permission. Changes without approval can put your agreement at risk.
Stacking funding is less about loopholes and more about planning. When you understand cost eligibility, disclosure rules, and assistance caps, combining programs becomes straightforward.
