If you’re searching for a secondary suite grant program in Ontario, here’s the straight answer: there is no single, province‑wide Ontario grant that pays homeowners to build a basement apartment or in‑law suite. Ontario sets the rules and permissions, but most real funding is local, delivered by municipalities using federal and provincial housing dollars.
That doesn’t mean help isn’t available. It just means you need to know where to look, what’s active in 2026, and what’s been cancelled.
Ontario’s role is mostly regulatory. The province allows secondary units in most areas and requires municipalities to permit them, subject to local bylaws. Actual money comes through three main paths:
Tools like GrantHub’s eligibility matcher can help you filter programs by province and municipality in seconds, which matters because funding changes city by city.
Many Ontario municipalities run secondary‑suite programs under housing or “Ontario Renovates” streams. These are often forgivable loans, not cash grants, but they function like grants if you meet the conditions.

Other Ontario examples include:
These programs open and close based on budgets. There is no central Ontario list.
If you’ve heard about a big federal loan for secondary suites, here’s the clarification.
Canada Secondary Suite Loan Program (Announced, Then Cancelled)
This program does not exist in 2026, despite still being mentioned online.
While not a grant, this change has real financial impact.
Insured‑Mortgage Refinancing for Secondary Suites
For many Ontario homeowners, this is the only viable way to fund construction without a municipal program.
Some large cities support secondary units by reducing costs instead of issuing grants.

These incentives don’t put money in your pocket, but they can save tens of thousands upfront.
Most municipal programs share similar rules:
Missing any one requirement can disqualify your application.
Assuming Ontario has a province‑wide grant
It doesn’t. Funding is local, and searching only “Ontario grants” often leads nowhere.
Starting construction before approval
Many programs require approval before permits or work begins.
Ignoring affordability conditions
Forgivable loans can become repayable if rent limits or occupancy rules are broken.
Relying on outdated federal programs
The $80,000 federal secondary suite loan was cancelled and is not available.
Q: Is there a province‑wide secondary suite grant program in Ontario?
No. Ontario sets the policy framework, but funding is delivered by municipalities or through federal financing measures.
Q: Are forgivable loans the same as grants?
Functionally, yes—if you meet the conditions. If you don’t, you may have to repay part or all of the loan.
Q: Can landlords apply, or only homeowners?
Most programs require you to live in the home. Investor‑owned properties are often excluded.
Q: Is mortgage refinancing my only option if my city has no program?
In many cases, yes. The federal insured‑mortgage refinancing rules are currently the most widely available option.
Q: How do I find programs for my specific Ontario city?
You need to check municipal housing departments or use a centralized database that tracks local programs.
Because there’s no single secondary suite grant program in Ontario, the key is matching your city, income level, and project type to what’s actually open right now. GrantHub tracks 2,500+ active grant and incentive programs across Canada—including municipal housing funding—so you can see which ones fit your property and location.
