Many Canadian businesses think they can only use one grant per project. That isn’t true. In most cases, you can combine several grants to fund one project in Canada, as long as each program allows it and you follow the stacking rules set by funders.
Grant stacking is common for R&D, hiring, training, and market expansion projects. Federal and provincial funders expect businesses to blend funding sources, but they also set limits on how much public money you can receive.
Grant stacking means using more than one government funding program to pay for different parts of the same project. Each program covers specific eligible costs, not the entire project.
Most Canadian grant programs follow these main rules:
These limits are called stacking limits or maximum government assistance.
You can usually combine grants that support different cost categories or different stages of a project.

Scientific Research and Experimental Development (SR&ED) offers federal tax incentives for eligible R&D work in Canada
These two programs are often used together because IRAP support guides the project during the year, while SR&ED is claimed after the project through your corporate tax return. SR&ED is a tax credit, not direct grant funding. You must reduce your SR&ED claim by any government assistance received for the same costs.
Many provinces let their grants stack with federal programs, as long as you stay under the total funding cap. Each grant application will ask you to list other confirmed or pending funding.
GrantHub’s eligibility matcher helps you filter programs by province, industry, and cost type quickly.
Before applying, list your expenses clearly:
This helps you match each cost to the right program.
Every grant has a section called “Stacking limits,” “Maximum government assistance,” or “Other funding.” This section tells you:
For example:
Never claim the same dollar twice.
Grant officers check funding across programs. If you hide another application, you risk rejection or funding clawbacks later. Being transparent improves credibility.
Use separate budget lines or accounting codes for each grant. This makes reporting easier and protects you if you’re audited.
This is the fastest way to lose funding. Each dollar can only be reimbursed once.
Even if programs allow stacking, total government funding may be capped. Exceeding the cap can trigger repayment.
Programs like SR&ED count as government assistance and affect stacking calculations.
Some grants require approval before costs are incurred. Others, like SR&ED, are claimed after the project.
Q: Is it legal to combine multiple grants for one project in Canada?
Yes. Most funders expect businesses to combine funding sources, as long as stacking rules are respected and expenses are not double-claimed.
Q: Do federal and provincial grants count toward the same stacking limit?
Yes. Stacking limits usually apply to all government funding combined — federal, provincial, and municipal.
Q: Does SR&ED affect other grants?
Yes. SR&ED is considered government assistance. You must reduce your SR&ED claim by other government funding received for the same costs.
Q: Can I combine grants and loans?
Usually yes. Loans often count differently than non-repayable grants, but you must still disclose them.
Q: What happens if I exceed the stacking limit?
You may have to repay the excess funding or have future payments reduced.
Combining multiple grants can lower your out-of-pocket costs, but you must plan the stack carefully. GrantHub tracks over 2,500 active grant programs across Canada and shows which ones can work together based on your business profile.
