Frequently asked questions
Is the CMHC premium added to my mortgage?
Yes. The mortgage loan insurance premium is calculated on the loan amount and may be added to the principal you repay. Quebec tax on that premium is paid in cash at closing and cannot be financed.
What Quebec tax rate applies to the premium?
For a premium paid in 2026, the rate is 9%. Revenu Québec will use 9.975% (harmonized with QST) for premiums paid after 31 December 2026. This calculator applies the rate from the closing date you enter.
Can I use a 30-year amortization with CMHC insurance?
On an insured loan, 30-year amortization is mainly for first-time buyers and new construction. Beyond 25 years, CMHC adds a 0.20% surcharge on the premium.
What is the minimum down payment?
For an insured loan: 5% on the first $500,000, then 10% on the portion between $500,000 and $1,500,000. From $1,500,000, the minimum is 20% and the loan is generally no longer CMHC-insurable.
