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 afford, especially with today’s rates and stress-test rules?
There’s no one-size-fits-all number. In Canada, affordability depends on your income, your debt, your down payment, and even the type of mortgage you qualify for. A lender uses a combination of income ratios, stress-testing rules, and your real financial picture to determine your maximum price.
This article will break down how it works, in plain English, so you can shop with confidence.
1. What lenders look at first: income and debt
When a lender reviews your mortgage application, the first step is simple: how much money comes in each month, and how much goes out?
You can earn a solid income, but if your monthly payments are stretched thin, that will limit your mortgage approval. On the flip side, even a moderate income can support a healthy approval if you keep other debts low.
This brings us to the core affordability rule in Canada: the 39/44 ratios.

2. Understanding the 39/44 rule (GDS and TDS)
You’re here because you’re wondering “how much house can I afford?” Lenders in Canada typically follow two affordability ratios:
GDS — Gross Debt Service Ratio (39% max)
GDS looks at housing costs only, including mortgage payment (principal + interest), property taxes, heat, and 50% of strata fees (if applicable).
Your GDS ratio should generally not exceed 39% of your gross income.
TDS — Total Debt Service Ratio (44% max)
TDS includes all housing costs plus all other debts: car payments, credit cards (minimum monthly payment count), lines of credit, student loans, personal loans, support payments if applicable.
Your TDS should not exceed 44% of your gross income.
In real terms: If you earn $100,000 annually ($8,333/month before tax), your total housing costs ideally stay under ~$3,250/month, and all debts together should remain under ~$3,666/month.
3. Monthly income vs monthly expenses—how they factor in
A lender doesn’t look at “bank balance comfort.” They look at math. You might feel you can comfortably pay $4,000/month because you don’t spend much recreationally. But unless the numbers fit within the required ratios and stress-test rules, the approval will follow the formula — not your lifestyle preferences.
That said: your personal comfort level matters just as much. A pre-approval tells you what the lender is willing to lend. It does not tell you what will feel comfortable day to day.
Once you see the qualified amount, take a moment to check:
- Your current lifestyle spending
- Childcare costs
- Vehicle expenses
- Groceries and inflation
- Travel habits
- Emergency fund
That’s how you turn “approval” into “smart decision”.
4. Insured mortgages up to $1.5 M — what’s new
For buyers using an insured mortgage (i.e., less than 20% down), the purchase-price cap has increased: insured mortgages can now go up to $1.5 million. That opens the door in higher-priced markets like BC.
5. Down payment basics (quick refresher)
- Minimum 5% for homes under $500,000
- 10% on the portion from $500,000–$1,500,000
- 20% minimum for all homes $1.5 million+ or rental properties
A higher down payment reduces your mortgage and monthly payment, but the minimum rules are there to get you into the market without years of saving.
6. Stress test: it’s still around (for now)
In Canada you must qualify at the higher of your actual contract rate or the benchmark qualifying rate. That means even if your rate is 4.5%, you must prove you can afford 6.5% (or whatever the benchmark is at application time).
This protects you (and the lender) from rate shocks—important in times like today.
