Many Canadian businesses leave money on the table because they assume you can only use one grant per project. That is not true. In most cases, you can combine grants, tax credits, and advisory programs—as long as you follow the stacking rules set by each funder. Knowing how to stack multiple government funding programs for one project can reduce your out‑of‑pocket costs by tens or even hundreds of thousands of dollars.
Stacking means using two or more government programs to support different parts of the same project. The key rule is simple:
You cannot be reimbursed twice for the same dollar of expense.
Most Canadian funders allow stacking, but they cap the total government assistance you can receive. This is often called a stacking limit or maximum assistance level.
Common stacking combinations include:
Most federal and provincial programs limit total government funding to 50%–75% of eligible project costs. Some go higher for not‑for‑profits or priority sectors.
Always check:
You need a clean budget that shows:
Good record‑keeping is not optional. It is often reviewed during audits.
Every application will ask you to list:
Failing to disclose is one of the fastest ways to lose funding—even after approval.
Start with your full project budget
Break costs into wages, contractors, equipment, and overhead.
Match programs to cost types
Example:
Check stacking limits early
Do this before you apply, not after approval.
Align timelines
Some programs pay during the project. Others, like SR&ED, pay months later.
Track everything in one place
Tools like GrantHub’s eligibility matcher can help you filter programs by province and industry in seconds.
The Scientific Research and Experimental Development (SR&ED) Tax Incentive Program supports eligible R&D work in Canada through tax credits.
Key SR&ED facts:
SR&ED is often stacked with:
Important: Any grant funding received for R&D expenses must be deducted when calculating your SR&ED claim.
The National Research Council of Canada Industrial Research Assistance Program (NRC IRAP) offers free advisory services to eligible Canadian SMEs working on science‑ or engineering‑based innovation.
Key details:
Because advisory support is non‑financial, it often stacks cleanly with:
Double‑counting the same expense
Claiming the same wage dollar under two programs will trigger clawbacks.
Ignoring tax credits in stacking calculations
Many businesses forget that SR&ED counts as government assistance.
Applying in the wrong order
Some programs require approval before costs start.
Assuming “non‑repayable” means unlimited
Grants still have caps and reporting obligations.
Q: Can I stack federal and provincial grants for one project?
Yes, in most cases. You must stay within the total government assistance limit set by each program and clearly disclose all funding sources.
Q: Do tax credits like SR&ED count as stacking?
Yes. SR&ED is considered government assistance and must be factored into stacking limits.
Q: Can I stack advisory programs with grants?
Usually yes. Programs like NRC IRAP advisory services do not provide cash and typically do not affect stacking limits.
Q: What happens if I exceed a stacking limit?
The funder may reduce your payment or require repayment after an audit.
Q: Can startups stack more funding than established businesses?
Sometimes. Early‑stage companies and priority sectors may have higher allowable assistance levels.
GrantHub tracks hundreds of active grant programs across Canada—check which ones match your business profile and how they can work together.
Stacking funding works best when you plan before you apply. Map your project, understand the limits, and choose programs that complement each other. GrantHub helps you see which grants, tax credits, and advisory programs can fit together—so you build a funding strategy that actually holds up under review.
