CMHC Mortgage Insurance Explained

October 14, 2026 · 1 min read

Mortgage default insurance protects the lender if a borrower stops paying. It’s the reason Canadians can buy with as little as 5% down, and why insured mortgages often get the lowest rates.

When is it required?

Any mortgage with a down payment below 20% must be insured through CMHC, Sagen or Canada Guaranty. Insured mortgages are available on homes priced below $1.5 million.

How much does it cost?

Down payment Premium (% of mortgage)
5% – 9.99% 4.00%
10% – 14.99% 3.10%
15% – 19.99% 2.80%

A 0.20% surcharge applies to 30-year amortizations. The premium is added to your mortgage, but in Ontario the 8% PST on the premium is due in cash at closing.

Example

$600,000 home, 10% down ($60,000). Mortgage: $540,000. Premium: 3.10% = $16,740 added to the mortgage. PST: $1,339 paid at closing.
