What is CMHC Mortgage Insurance & How Does It Work?

Mortgage default insurance — commonly called CMHC insurance — is legally required in Canada whenever your down payment is less than 20% of the purchase price and the home is $1,500,000 or less. It protects the lender (not you) if you stop making mortgage payments. Because lenders are protected, they can offer lower interest rates to high-ratio borrowers.

The premium is added to your mortgage balance — you don't pay it as cash at closing. However, if you live in Ontario, Quebec, or Saskatchewan, your province charges PST/QST on the premium, and that tax must be paid in cash through your lawyer on closing day. It cannot be added to your mortgage.

As of December 15, 2024, insured mortgages are available for homes priced up to $1,500,000 (up from $1,000,000). First-time buyers and buyers of new construction may qualify for a 30-year amortization — the standard maximum is 25 years. The 30-year option carries a 0.20% surcharge on the premium rate, as confirmed by CMHC effective August 1, 2024.

Reduce Your Premium

Each LTV tier has a dramatically different premium rate. Saving just a bit more to cross a threshold — say from 9% to 10% down — drops your rate from 4.00% to 3.10%, saving you thousands. Run this calculator with different down payments to see the impact.

Portability — Don't Pay Twice

If you move and your new home is more expensive, you may only pay a premium on the increased loan amount, not the entire mortgage. CMHC's portability feature provides premium credits up to 100% within 6 months, 50% at 12 months, and 25% at 24 months.

Eco Plus — 25% Refund

Buying or building an energy-efficient home? CMHC Eco Plus offers a 25% partial refund on your premium. The home must meet an eligible EnerGuide rating. Ask your lender whether your purchase qualifies before closing — the application window is limited.

Three Approved Insurers

CMHC, Sagen (formerly Genworth Canada), and Canada Guaranty all charge identical premium rates. Your lender chooses the insurer — you don't. All three are federally regulated and offer the same consumer protections.
