How Canadian mortgage affordability works
Canadian lenders apply two standardized tests: GDS and TDS, both calculated at the stress test rate (your contract rate + 2% or 5.25%, whichever is higher). CMHC raised the GDS limit from 32% to 39% in December 2024, meaningfully increasing what many Canadians can qualify for.
Your maximum purchase price is determined by whichever constraint binds first — GDS or TDS. Adding a co-applicant, reducing debts, or increasing the down payment all improve your qualifying power.
