How CMHC Insurance Works

CMHC mortgage insurance is mandatory for all home purchases in Canada where the down payment is less than 20% of the purchase price. The insurance premium is calculated as a percentage of the mortgage amount (not the purchase price) and is added directly to your mortgage balance.

Example: $500,000 home, $30,000 down (6%), mortgage = $470,000. CMHC premium at 4.00% = $18,800. Total insured mortgage = $488,800. In Ontario and Quebec, you also pay provincial sales tax on the premium upfront (not added to mortgage).

Is CMHC Insurance Tax-Deductible?

For owner-occupied homes, CMHC insurance premiums are not tax-deductible. However, if the property is a rental or investment property, you may be able to deduct it over time. Consult a tax professional for your specific situation.

Provincial Sales Tax on CMHC Premiums

In Ontario and Quebec, provincial sales tax applies to the CMHC premium. Unlike the premium itself (which is added to your mortgage), the provincial tax must be paid in cash at closing — it cannot be rolled into your mortgage.

Is CMHC Insurance Worth It?

CMHC insurance enables home ownership earlier by allowing a 5% down payment instead of waiting to save 20%. For many Canadians, the insurance cost (paid over 25 years through a marginally higher mortgage balance) is far outweighed by getting into the market sooner and benefiting from property appreciation.
