How to Combine Multiple Government Grants for One Project in Canada

Many Canadian businesses believe you can only use one government grant per project. That’s not true. In many cases, you can combine multiple government grants for one project in Canada, as long as you follow stacking rules and cost-sharing limits set by funders.

Grant stacking can help you pay for more of your project, lower your risk, and speed up your work. The key is to know which programs can work together. You also need to understand the limits for each grant.

How Grant Stacking Works in Canada

“Grant stacking” means using more than one source of public funding for the same project. These sources can include:

Federal grants
Provincial or territorial grants
Municipal funding
Crown corporation or agency programs
Non-repayable contributions from government-funded organizations

Most Canadian grant programs allow stacking, but they cap the total amount of government funding you can receive.

The most common stacking rule

For for-profit businesses, the usual limit is:

Up to 75% of total eligible project costs covered by government funding

For not-for-profits, Indigenous organizations, or academic institutions, the cap is often higher:

Up to 90–100% of eligible costs, depending on the program

Each program sets its own maximum. You must follow the strictest rule among the grants you combine.

Federal, Provincial, and Municipal Grants: How They Fit Together

One common and effective strategy is to mix funding across government levels.

Federal grants often fund innovation, hiring, or scale-up
Provincial grants may support the same project with regional priorities
Municipal programs sometimes add small top-ups or incentives

Most federal programs allow stacking with provincial and municipal funding—but they still count toward your total government funding percentage.

Always disclose:

Program name
Funding amount
Approval status (approved, pending, or applied)

Not sharing all funding sources can lead to clawbacks later.

How to Plan Your Grant Applications

Planning is important when you want to combine grants. Make a list of the grants you want to apply for. Check their deadlines, stacking rules, and eligible costs. Make sure the project budget matches across all applications.

Tips for planning:

Start early and check timelines for each grant
Use tools like GrantHub’s eligibility matcher to quickly find grants by province, industry, and project start date
Prepare a single project budget to use across all applications
Keep track of your applications and approvals in one place

Careful planning helps you avoid mistakes and increases your chances of success.

What You Can (and Cannot) Fund Twice

You can combine grants in two main ways.

1. Different grants covering different expenses

This is the safest approach.

Example:

Grant A covers employee wages
Grant B covers equipment or software
Grant C supports training or advisory services

As long as each dollar of cost is claimed once, stacking is usually allowed.

2. Multiple grants contributing to the same expense category

This is allowed only if:

The combined funding stays under the stacking cap
All funders clearly permit stacking
You openly share all funding sources

You can never claim more than 100% of an expense, even if programs allow stacking.

Timing Matters More Than Most Businesses Realize

You usually cannot apply retroactively.

Common timing rules:

Applications must be submitted before project start
Some programs require written approval before costs are incurred
Others allow costs after submission but before approval

If you plan to combine grants, align timelines early. Tools like GrantHub can help you filter programs by province, industry, and project start date in seconds.

How to Disclose Multiple Grants Properly

Every grant application will ask about other funding.

Best practices:

List all government funding sources, even if pending
Use the same project budget across applications
Make sure totals match your stacking limits
Keep written records of approvals and amendments

Funders often compare applications across departments. Inconsistencies raise red flags.

Common Mistakes to Avoid

Double-claiming the same cost
You cannot charge the same wage, invoice, or expense to two grants.

Exceeding the maximum stacking limit
Even if each program approves you individually, you must stay under the combined cap.

Starting the project too early
Incurred costs before eligibility dates are often rejected.

Not reporting changes
If you receive new funding after approval, you may need to notify existing funders.

Frequently Asked Questions

Q: Can I combine federal and provincial grants for the same project?
Yes, in most cases. The combined funding must stay within the maximum stacking percentage set by each program.

Q: Do loans and tax credits count toward stacking limits?
Usually no. Repayable loans and refundable tax credits are often excluded, but always check program guidelines.

Q: What happens if I exceed the stacking limit?
You may have to repay part of the funding or have future claims reduced.

Q: Do I need approval from all funders before stacking grants?
You don’t need advance approval to stack, but you must disclose all funding sources accurately.

Q: Can not-for-profits stack more funding than businesses?
Often yes. Many programs allow higher coverage for not-for-profits and Indigenous organizations.
