How much mortgage can I afford in Ontario?
Stress-tested at the greater of contract +2% or 5.25% — the same math a federally regulated lender will run on your file. Province-aware: includes land transfer tax and closing costs so you see real cash-needed-at-closing, not just the qualifying mortgage.
How much you can afford isn't set by your real rate — it's set by the stress test, which qualifies you at the greater of your rate +2% or 5.25%. This calculator runs that math with your income, debts and down payment, then adds your province's land transfer tax and closing costs so you see the real cash needed at closing, not just the qualifying mortgage. Enter your numbers above.

How lenders decide what you can afford
Affordability in Canada is governed by two debt-service ratios, both measured at the qualifying (stress-test) rate — the greater of your contract rate +2% or 5.25%. Your Gross Debt Service (GDS) ratio caps housing costs (principal, interest, property tax and heat) at roughly 39% of gross income. Your Total Debt Service (TDS) ratio caps housing plus every other monthly obligation at about 44%.
Whichever ratio you hit first becomes your binding limit. That is why paying down a car loan or credit-card balance can lift your maximum purchase more than a small income bump — it frees up room under the 44% TDS ceiling. The bars below show exactly where your file lands against both limits.
Want to push the number higher? Compare lenders with our stress test calculator — some provincial credit unions qualify at contract rate — or see the income behind any price with our income-required calculator.
Your debt-service ratios vs. lender limits
Computed at the 5.94% qualifying rate. Staying under both bars is what gets your file approved.
GDS counts principal, interest, property tax and heat. TDS adds your other monthly debt of $450. A green bar means you clear the limit with room to spare; a red bar means the limit is capping your maximum purchase.
