Frequently Asked Questions

How much is CMHC insurance in Canada?

The premium depends mainly on the loan-to-value ratio, which reflects the mortgage amount compared with the property's value. A smaller percentage down payment generally produces a higher insurance premium rate.

When do I need CMHC mortgage insurance?

Mortgage default insurance is generally required for eligible purchases when the down payment is below 20%. Eligibility also depends on the purchase price, property and mortgage rules in effect at the time.

Can CMHC insurance be added to the mortgage?

The mortgage default insurance premium can generally be added to the mortgage balance. Any provincial tax that applies to the insurance premium is normally handled separately and may need to be paid at closing.

Does a larger down payment reduce CMHC insurance?

Yes. A larger down payment lowers the loan-to-value ratio and can reduce the premium. With a down payment of at least 20%, mortgage default insurance is generally not required for a conventional mortgage.

Do I pay sales tax on CMHC insurance?

It depends on the province. Some provinces apply a provincial tax to mortgage default insurance premiums, so the cash required at closing may include tax even when the premium itself is added to the mortgage.

How this estimate works

The premium is the mortgage before insurance multiplied by the applicable Canada Mortgage and Housing Corporation (CMHC) loan-to-value ratio. Eligible 30-year insured amortizations add 0.20 percentage points. The premium may be financed; applicable provincial tax may not.

Final eligibility and premium are determined by the mortgage insurer and lender. This calculator models standard homeowner purchase premiums and does not cover portability, refinance, multi-unit rental or non-traditional down-payment surcharges.
