Mortgage Stress Test FAQ
The qualifying rate formula (max of 5.25% or contract + 2%) applies to both insured (CMHC) and uninsured mortgages. Key differences: (1) Insured mortgages are limited to homes under $1.5M; (2) First-time homebuyers and new-build purchasers can now access 30-year amortizations with insured mortgages (changed August 2024 — previously only uninsured); (3) Since November 21, 2024, borrowers switching lenders at renewal with no balance/amortization change are exempt from the stress test.
GDS (Gross Debt Service) includes: (1) monthly mortgage payment at the stress-test rate, (2) property taxes (estimated at ~1% of home value annually / 12), (3) heating costs (lenders typically use $150/month as a standard estimate), and (4) 50% of monthly condo fees (if applicable). GDS must not exceed 39% of gross monthly income.
Yes. Most major Canadian banks (RBC, TD, Scotiabank, CIBC, BMO) offer Newcomer Mortgage Programs that reduce or waive traditional credit history requirements. Typical requirements: (1) valid PR card or work permit with 2+ years remaining, (2) employment income confirmation, (3) 5–35% down payment depending on the program. The standard stress test still applies to all borrowers.
