Canada's GDS/TDS Rules vs. US 28/36 DTI
Gross Debt Service (GDS) — 32%
The GDS ratio limits your mortgage principal and interest, property taxes, and heating costs to 32% of your gross monthly income. On C$50,000/year, that is C$1333/month. This is similar to the US "front-end" 28% rule, but set higher at 32% for insured Canadian mortgages.
Total Debt Service (TDS) — 40%
The TDS ratio adds all other monthly debt obligations (car loans, student debt, credit cards) to housing costs. The maximum TDS is 40% for insured mortgages and up to 44% for conventional mortgages — equivalent to the US "back-end" 36% rule but more flexible.
OSFI Stress Test: Canada requires all mortgage applicants to qualify at max(contract rate + 2%, 5.25%). At today's rates, the qualifying rate is 7.24%, even if your actual rate is lower. This significantly reduces maximum purchasing power compared to face-value rate calculations.
