How It Works

CMHC Premium Rate Table

The CMHC premium rate depends on your down payment percentage. Rates apply to the base mortgage amount (purchase price minus down payment) and are added to your loan balance.

Down Payment %CMHC Premium RateExample on $600K home
5% – 9.99%4.00%$22,800 on $570K mortgage
10% – 14.99%3.10%$16,740 on $540K mortgage
15% – 19.99%2.80%$14,280 on $510K mortgage
20% or moreNone$0 — conventional mortgage

Minimum Down Payment Rules

The federal minimum down payment in Canada is tiered by purchase price:

  • $500,000 or less:Minimum 5% of the full purchase price.
  • $500,001 – $1,499,999:5% on the first $500,000 + 10% on the portion above $500,000.
  • $1,500,000 or more:CMHC insurance is unavailable — 20% conventional down payment required.

How the Premium Is Applied

The CMHC premium is not paid upfront at closing (except for the provincial sales tax portion in applicable provinces). Instead, it is added directly to your mortgage balance and amortized over your full amortization period at your contracted interest rate. This means the actual cost of the premium over time is higher than the face value — for example, a $20,000 premium on a 25-year mortgage at 5.50% adds roughly $35,000 in total principal and interest payments.

30-Year Amortization — Eligibility

As of December 15, 2024, CMHC-insured mortgages may have an amortization of up to 30 years when the borrower is a first-time homebuyer or is purchasing a newly constructed home. Without one of these conditions, the maximum insured amortization is 25 years. Conventional mortgages (20%+ down) are not subject to this restriction.
