Your result, explained
Based on your income, debts and deposit, lenders would likely approve a home of up to about $798,578, with a $718,578 mortgage costing around $4,696 a month.
That is the maximum a lender allows, not necessarily what is comfortable. Leave room for savings, repairs and rate rises: many buyers aim 10–20% below the maximum. Paying off a car loan or credit card first is often the fastest way to raise your budget, because every monthly debt payment reduces what you can borrow.

GDS, TDS and the stress test
Canadian lenders cap your gross debt service (housing costs) at 39% of income and total debt service at 44%. They calculate it at a stress-test rate: the greater of your contract rate plus 2% or 5.25%. That is why approval amounts are lower than your actual payment suggests.
