Two material federal mortgage policy changes took effect in late 2024 and apply throughout 2026: the price cap on insured mortgages rose from $1,000,000 to $1,500,000, and 30-year amortization is now available on insured mortgages for first-time home buyers and for purchases of newly constructed homes. The OSFI B-20 stress test rule (qualifying at the higher of contract rate plus 2% or 5.25%) is unchanged.

Why the price cap change matters
Before the change, a buyer in Toronto or Vancouver wanting to purchase a $1,200,000 home was required to put down 20% ($240,000) because no insurer would back a mortgage on a property over $1,000,000. The new cap of $1,500,000 means buyers in expensive markets can put 5% down on the first $500,000 and 10% on the remainder up to $1,500,000, dramatically lowering the cash-down requirement.
For a $1,200,000 home, the new minimum down payment is $25,000 (5% × $500,000) + $70,000 (10% × $700,000) = $95,000, or 7.9% of the purchase price. The mortgage of $1,105,000 is then insured (with the CMHC premium added to principal).
Why the 30-year amortization change matters
Insured mortgages were previously capped at 25-year amortization. The new 30-year option (for first-time buyers and new construction) lowers monthly payment, making more buyers eligible under the GDS/TDS ratio limits. The trade-off: the CMHC premium has a 0.20% surcharge for 30-year amortization, and total interest paid over the life of the mortgage is meaningfully higher.
What did not change
The OSFI B-20 stress test (qualifying at the higher of contract rate plus 2 percentage points or 5.25%) is unchanged. The 39% GDS limit and 44% TDS limit for insured mortgages are unchanged. The CMHC premium percentages by LTV tier are unchanged.
