How the Canadian mortgage stress test works

Introduced in 2016 and expanded in 2018, the stress test ensures Canadians can handle higher rates at renewal. Lenders calculate your GDS and TDS ratios at the stress test rate — not your actual rate — before approving your mortgage.

The stress test rate is the greater of your contract rate + 2% or 5.25%. With today's rates around 3.89% fixed, most borrowers face a stress test rate of 5.89%.

The stress test was designed exactly for what happened in 2022–2023 when rates spiked: borrowers who passed the stress test could handle the higher payments; those who hadn't been stress tested couldn't.
