How Much House Can I Afford in Canada? A Mortgage Guide

Buying a home changes your life. But before you fall in love with a kitchen on Instagram, the big question hits: how much house can I actually afford, especially with today’s rates and the stress test in play?

There’s no single answer. In Canada, affordability comes down to your income, your debt, your down payment, and the type of mortgage you qualify for. Lenders combine income ratios, stress-test rules, and your real financial picture to land on your maximum price.

What lenders look at first: income and debt

The first thing a lender checks is simple — how much comes in each month, and how much goes out? A solid income can still be limited by tight monthly payments elsewhere, and a moderate income with low debt can support a healthier approval than you’d expect.

The 39/44 rule (GDS and TDS)

Lenders lean on two ratios to make sure you’re not “house poor”:

GDS — Gross Debt Service (39%). Housing costs only: mortgage principal and interest, property taxes, heat, and 50% of strata fees. This shouldn’t exceed 39% of your gross income.

TDS — Total Debt Service (44%). Everything in GDS, plus car payments, credit cards, student loans, and lines of credit. All of it together should stay under 44%.

Example: on $100,000 a year ($8,333/month before tax), housing costs should stay under roughly $3,250/month, and all debts together under roughly $3,666/month.

Monthly income vs. lifestyle comfort

A lender looks at the math, not your comfort level. Your comfort level is still up to you — once you know your qualified amount, take a beat to weigh it against childcare, groceries, inflation, and your emergency fund. That’s the difference between an “approval” and a genuinely smart decision.

The stress test: contract rate + 2%

In Canada, you don’t just need to qualify at your actual contract rate. You have to prove you can afford the higher of your contract rate plus 2%, or the benchmark qualifying rate (currently 5.25%). So even at a 4.15% rate, the bank checks whether you can handle 6.15% — a safety net for you and for them if rates are higher when you renew.

Insured mortgages up to $1.5M

The purchase-price cap for insured mortgages (under 20% down) now sits at $1.5 million, which gives buyers in higher-priced markets a way in using a tiered down payment on homes above $1 million.

Down payment quick refresher

• 5% minimum on homes under $500,000
• 10% on the portion between $500,000 and $1.5 million
• 20% minimum on homes $1.5 million and up, or on rental properties
