A youth soccer club wins a federal grant for a new inclusive program, then gets good news from the province and the city for the same program. Three cheques, one project. It feels like a windfall until a program officer asks a question the club never thought about: how much of this project is now paid for by government in total? In Canada, that question has a name, the stacking limit, and getting it wrong can mean repaying money after the project is finished.
The short answer to "can you combine multiple grants for one project?" is yes, usually. Grant stacking is common and often encouraged. But nearly every government program sets rules about how far it can go. This article explains how stacking limits work, shows real examples from federal and Alberta programs, and gives you a simple way to stay compliant.
What Grant Stacking Means in Canada
Stacking simply means funding one project from more than one source. A federal program might cover part of a project, a provincial grant another part, a community foundation a third, and your own fundraising the rest. Funders generally like this. It spreads risk and shows broad support.
What funders do not allow is double funding: being paid twice for the same cost, or receiving more in total than the project actually costs. Stacking limits are the rules that prevent this. In federal programs, the limit is typically expressed as the maximum total government assistance, meaning combined federal, provincial, territorial and municipal funding, as a percentage of eligible project costs.
Stacking is not the problem. Hiding it is. Funders expect you to combine sources; they need to see every one of them to make sure no cost is paid twice.
Real Stacking Rules From Canadian Programs
Here are examples taken from current program guidelines. They show two kinds of limit: a cap on how much one program will pay, and a cap on how much all governments together will pay.
| Program | Program's own cap | Total government assistance limit |
|---|---|---|
| Canada Cultural Spaces Fund (Canadian Heritage) | Up to 50% of total eligible expenses, except in exceptional circumstances | Cannot exceed 100% of total project-related costs |
| Community Sport for All Initiative (Canadian Heritage) | Set by the program | Cannot exceed 100% of total project-related expenditures |
| Canada History Fund (Canadian Heritage) | Set by the program | Cannot exceed 100% of total eligible project-related costs |
| Community Facility Enhancement Program (Alberta) | Must be matched by the applicant at least one-to-one | Total Government of Alberta funding cannot exceed 50% of total project cost |
Notice the difference between the Canadian Heritage programs and CFEP. The federal examples cap all levels of government combined at 100%, so a project could, in principle, be fully government-funded as long as nothing is paid twice. CFEP caps provincial money only at 50% of total project cost, and it does not allow other Government of Alberta funding to count toward your match. That means stacking two Alberta grants on one facility project is tightly limited, while stacking an Alberta grant with municipal, federal or private money is a normal way to build a budget.
Not every program publishes its limit in the same way. The New Horizons for Seniors Program, for example, asks applicants to list every source of funding in the project budget, including other governments, and caps each request at $50,000. Always confirm current guidelines on the funder's website before applying.
What Happens if You Exceed a Stacking Limit
Stacking limits are written into federal transfer payment programs under Treasury Board policy, and program terms commonly say that if a recipient's total government assistance ends up above the limit, the department will reduce its contribution and may seek repayment. In practice, that can mean:
- A smaller final payment than you budgeted for.
- A request to repay funds after your final report.
- Questions about your financial controls that follow you into future applications.
Most problems are accidental: a late municipal grant that arrives after the federal agreement is signed, or a provincial top-up nobody thought to report. Read the reporting clauses of your agreement; many require you to tell the funder about new sources of funding for the project. Our guide to grant compliance and reporting covers what usually happens after you win.
Do Private Foundation Grants Count Toward Stacking Limits?
Federal stacking limits are usually defined in terms of government assistance, so grants from private foundations, corporations and individual donors generally do not count toward that particular cap. They still count toward something more basic: you cannot receive more than the project costs, and you cannot charge the same expense to two funders. Private funders also ask about other sources, and they expect honesty. Always check how each program defines its limit and whether it treats a community foundation that distributes government money differently.
A Five-Step Process to Stack Grants Safely
- Build one master budget for the whole project. List every cost and every funding source, cash and in-kind, confirmed and pending.
- Assign each cost to a funder. Make sure each expense line is covered once. If two funders share a cost, split it explicitly, for example 60% and 40% of a coordinator's wage.
- Calculate the government share. Add every federal, provincial, territorial and municipal dollar and compare it with the strictest limit among your funders, using that funder's definition of eligible costs.
- Disclose everything in every application. Each funder should see the same total budget and the same list of sources, even ones that are still pending.
- Update funders when things change. If a new grant is approved or a source falls through, tell the funders whose agreements require it, before the final report.
Combining provincial and federal money well is a strategy in itself. Our article on provincial vs federal grants explains which to approach first, and our budget narrative guide shows how to explain a multi-source budget clearly.
A Hypothetical Stacking Example
Consider a community arts centre in Lethbridge planning a $400,000 renovation. It applies to the Canada Cultural Spaces Fund for $160,000, which is 40% and within the program's 50% cap. It applies to CFEP for $125,000, about 31% and within Alberta's 50% provincial cap. The city commits $40,000 and a local foundation $25,000. The centre raises the remaining $50,000 from donors and in-kind work.
Total government assistance is $325,000, or about 81% of project costs: under the 100% federal limit, and the provincial share stays under 50%. Each funder sees the full budget with all five sources listed. Before the CCSF would recommend approval, the centre also needs two-thirds of its total funding confirmed, so it times the municipal and foundation commitments to land first. The example is illustrative, but the arithmetic is exactly what program officers check.
Frequently Asked Questions
Can you combine multiple grants for one project in Canada?
Yes, in most cases. Funders generally welcome multiple sources, but government programs set stacking limits on how much total government assistance a project can receive, and you cannot be paid twice for the same cost.
What is a stacking limit?
A stacking limit is the maximum share of a project's eligible costs that may be covered by government funding from all levels combined. Several Canadian Heritage programs set it at 100% of project costs, while Alberta's CFEP limits total provincial funding to 50% of total project cost.
Do I have to tell a funder about my other grants?
Yes. Most application forms require you to list all funding sources, and many funding agreements require you to report new sources during the project. Undisclosed funding can lead to reduced payments or repayment.
Do foundation grants count toward government stacking limits?
Generally not, because federal stacking limits are usually defined as government assistance. However, total funding still cannot exceed the project's cost, and each funder's definition should be checked.
Stacking grants well can turn a project that seemed out of reach into one that is fully funded, as long as the budget is built carefully. Book a 10-minute discovery call and we'll help you map which sources can work together for your project.
