Insured vs Uninsured Mortgage: Down Payment Impact
If you can put down less than 20 % you will need CMHC insurance, which adds a premium to your loan, while a down payment of 20 % or more avoids that premium and changes the maximum amortization and stress‑test requirements. The two paths create distinct cost and qualification profiles.
Comparison Table
Below is a quick reference that highlights the primary differences between insured and uninsured mortgages. The table compares down‑payment thresholds, insurance requirements, maximum amortization periods, and typical stress‑test calculations.
While the exact numbers vary by lender, the structure remains consistent across most Canadian banks and credit unions. Use our mortgage calculator to see how each option influences your monthly payment and total interest over the life of the loan.
Cost Impact of Mortgage Insurance
When you borrow with less than a 20 % down payment, the lender must purchase mortgage insurance from CMHC, Genworth or Canada Guaranty. That premium is typically added to the principal, increasing the amount on which interest is charged.
Because the insurance premium is spread over the amortization period, the effect on your monthly payment can be modest, but the total cost of borrowing rises. The premium also reduces the maximum amortization you can request, often capping it at 25 years instead of the 30‑year limit available to uninsured loans.
Qualification Differences
Both insured and uninsured mortgages are subject to the federal stress test, but the required qualifying rate differs. For insured loans the stress‑test rate is the greater of the Bank of Canada’s five‑year benchmark or your contracted rate plus 2 percentage points. Uninsured loans use the same formula, but lenders may apply additional underwriting discretion, especially for high‑ratio borrowers.
Self‑employed applicants, newcomers, and those with non‑traditional income sources often find the insured route more straightforward because the insurance provides the lender with added security, allowing a broader range of documentation.
Scenario Considerations
If you have a 10 % down payment and a stable employment history, an insured mortgage lets you access the market sooner, but you will pay the insurance premium over the life of the loan. If you can save to reach a 20 % down payment, you avoid the premium, gain a longer amortization, and may qualify for a larger loan amount.
First‑time buyers frequently start with an insured mortgage and refinance to an uninsured loan once equity builds. This strategy can lower long‑term costs while preserving flexibility during the early years of homeownership. Learn more about first‑time buyer options on our first‑time home‑buyer mortgage page.
Which Should You Choose?
Choosing between insured and uninsured depends on three factors: how much cash you have for a down payment, how quickly you want to own, and your tolerance for higher total borrowing costs. If you need to move quickly and have less than 20 % saved, an insured mortgage is usually the practical path.
Conversely, if you can wait to accumulate a 20 % or larger down payment, the uninsured route reduces your overall cost, offers a longer amortization, and may give you more negotiating power with lenders.

FAQ
Do I have to pay mortgage insurance if I put down exactly 20 %?
No. A down payment of 20 % or more eliminates the requirement for CMHC‑type insurance, removing that premium from your loan balance.
Can I refinance from an insured to an uninsured mortgage later?
Yes. Once you have built enough equity to reach a 20 % down‑payment equivalent, you can refinance without insurance, often reducing your monthly payment and total interest.
How does the insurance premium affect my borrowing limit?
The premium is added to the loan amount, which can slightly reduce the maximum principal you can qualify for, especially when the lender caps amortization at 25 years for insured loans.
Will an uninsured mortgage require a higher credit score?
Lenders typically apply stricter credit criteria to uninsured loans because they lack the safety net of mortgage insurance. A strong credit history improves your chances of approval and may affect the stress‑test rate you need to meet.
