The CMHC 30% rule was set in an era when median rent and median income moved together. They haven't since 2015. Today the average one-bedroom in Toronto is roughly $2,350 and in Vancouver $2,550 — both require a gross income of about $94,000–$102,000 to fit inside the 30% ceiling. The actual median single-adult income in those cities is closer to $60–70K. The math forces compromises: roommates, basement units, satellite cities, or stretching to 40%+ of income.
Once you've maxed out your rent budget, the natural next question is "should I be buying instead?" Mortgage affordability uses different math — Canada's GDS/TDS ratios plus the OSFI stress test add a margin lenders don't apply to renters. Run the comparison with our mortgage affordability calculator or the rent vs buy calculator to see which side actually wins over 5–10 years.
If you arrived in Canada within the last 12 months, most landlords will ask for 6–12 months of rent up front in lieu of credit history, plus first-and-last. Some require a Canadian guarantor.
