How CMHC/SCHL Insurance Works

Understand mortgage default insurance in Canada.

CMHC (SCHL in French) is mortgage default insurance required when your down payment is less than 20%. It protects the lender, not you — but it lets you buy with as little as 5% down.

When it's required

  • Down payment below 20% on a home priced under $1.5M
  • Owner-occupied or second home (not rental)
  • Maximum 25-year amortization (30 years for some first-time buyers and new builds)

How the premium is calculated

The premium is a percentage of the mortgage amount, scaling with loan-to-value (LTV).

  • Up to 65% LTV: 0.60%
  • Up to 75% LTV: 1.70%
  • Up to 80% LTV: 2.40%
  • Up to 85% LTV: 2.80%
  • Up to 90% LTV: 3.10%
  • Up to 95% LTV: 4.00%

Example

On a $500,000 home with 5% down ($25,000), the insured mortgage is $475,000. Premium is 4.00% = $19,000, added to the mortgage. New principal: $494,000.

Pros and cons

  • Pro: buy sooner with less savings
  • Pro: insured mortgages often get a slightly lower rate
  • Con: premium adds thousands to what you owe
  • Con: PST on the premium is payable upfront in ON, QC and SK

Key takeaways

  • Required below 20% down
  • Premium is added to the mortgage, not paid in cash
  • Insured rates can be lower than uninsured
  • Avoidable by saving 20% — but the math doesn't always favor waiting
