Canadian mortgage rules.

The qualification rules and risk controls behind the calculators, in plain language.
AUTHORITATIVE LINKS
01

Minimum down payment

5% on the first $500,000 and 10% on the portion up to $1.5M; 20% at or above the insured-mortgage cap.

02

Stress test

Qualify at the higher of 5.25% or the contract rate plus 2 percentage points.

03

Amortization

30-year insured amortizations are available for eligible first-time buyers and buyers of new builds; otherwise common insured maximums are shorter.

04

Debt service

Common underwriting ceilings are 39% GDS and 44% TDS, but lenders and insurers can apply stricter rules.

05

Renewal risk

Most Canadian mortgages renew before full amortization, so payment and qualification risk can change at the end of each term.
