How Grant Stacking and Cost-Sharing Work in Canada

How Grant Stacking and Cost-Sharing Work in Canada

Many Canadian business owners think you can only use one grant at a time. That is not always true. Grant stacking and cost-sharing in Canada set rules for combining funding and paying your share of a project. If you get these wrong, you could face clawbacks or rejected claims.

Stacking limits how much public funding you can receive for the same costs. Cost-sharing defines how much your business must pay. These rules apply across federal, provincial, and regional programs. Each funder sets its own limits.

Grant Stacking vs. Cost-Sharing: What’s the Difference?

Grant stacking and cost-sharing are related, but they are not the same.

What Is Grant Stacking?

Grant stacking means using more than one government-funded program to support the same project or expense. Most Canadian programs allow this, but they cap the total government contribution.

Typical stacking rules:

• Public funding can cover 75%–100% of eligible costs, depending on the program and applicant type
• You must disclose all federal, provincial, territorial, and municipal funding
• Private investment does not count toward stacking limits

For example, if your eligible project costs are $100,000 and the stacking limit is 75%, all combined government funding cannot be more than $75,000.

What Is Cost-Sharing?

Cost-sharing is the portion of the project your business must pay. Even if stacking is allowed, most programs require you to contribute cash or eligible in-kind expenses.

Cost-sharing may include:

• Cash paid directly by your business
• Non-government third-party funding
• In-kind contributions like labour or equipment (if allowed)

Some programs reimburse expenses after you pay them, so you must cover cash flow upfront.

How Grant Stacking and Cost-Sharing Work Together

Funders check both rules at the same time.

Here is how it usually works:

• The program sets a maximum contribution rate (for example, up to 50% of eligible costs)
• It also sets a stacking cap (for example, up to 75% from all public sources combined)
• You must fund the rest through your business or private sources

If you get funding from another government program, the original funder may lower their contribution to stay within the stacking limit.

GrantHub’s eligibility matcher can help you filter programs by province and industry. This makes it easier to spot overlapping rules early.

Real-World Example: NRC IRAP and Cost-Sharing

The National Research Council of Canada Industrial Research Assistance Program (NRC IRAP) is a common example of cost-sharing.

NRC IRAP supports Canadian small and medium-sized businesses working on science or engineering-based innovation projects. IRAP gives advisory services for free, but funded innovation projects require businesses to share project costs. You must also disclose all other government funding.

Important points:

• IRAP funding cannot be stacked beyond program limits
• Other federal or provincial funding may reduce IRAP’s contribution
• Your business must show it can cover its share of costs

IRAP advisors review stacking and cost-sharing during the assessment stage. Being open and honest is important.

What Counts as “Government Funding” for Stacking?

Many businesses are unsure about this.

Usually included in stacking calculations:

• Federal grants and contributions
• Provincial and territorial programs
• Municipal funding
• Wage subsidies funded by government

Usually not included:

• Bank loans
• Angel or venture capital investment
• Owner’s equity

Always check the program guidelines. Definitions can change from funder to funder.

Common Mistakes to Avoid

1. Not disclosing other funding
   If you do not list all government support, you may have to pay back funds later.

2. Assuming programs don’t share information
   Many funders check funding databases at both federal and provincial levels.

3. Misunderstanding eligible costs
   Stacking applies only to eligible expenses, not your full project budget.

4. Ignoring cash flow timing
   Cost-sharing often means you pay expenses upfront before getting reimbursed.

Frequently Asked Questions

Q: Can I use federal and provincial grants together?
Yes, often. You must stay within the stacking limit set by each program and disclose all government funding.

Q: Does grant stacking apply to tax credits?
Sometimes. Refundable tax credits may count toward stacking limits, depending on the program. Always check the guidelines.

Q: What happens if I exceed the stacking limit?
The funder may reduce their contribution or ask you to repay extra funding.

Q: Is cost-sharing always cash?
Not always. Some programs accept in-kind contributions, but only if they are eligible and documented.

Q: Can early-stage businesses qualify if they can’t cover the full cost-share?
Some programs allow lower cost-sharing for startups, but you must still show financial capacity.
