How much house can you actually afford?
Short answer: Canadian lenders use two debt-service ratios: GDS (max 39%) and TDS (max 44%). GDS = (mortgage payment + property tax + heat + 50% of condo fees) ÷ gross monthly income. TDS = GDS plus all other debt obligations. A rough rule of thumb: you can afford a mortgage of about 4× to 4.5× your gross household income with average tax, decent credit, and minimal other debt. In Toronto and Vancouver most buyers end up at 6-8× income with parental help or larger down payments.
Worked example for a household earning $130,000/year:
- Monthly gross income: $10,833
- GDS limit at 39%: $4,225/month for housing (mortgage + tax + heat + condo fees)
- Assume property tax $400/mo, heat $80/mo, no condo: $4,225 - $400 - $80 = $3,745/mo available for mortgage payment
- At stress test rate (6.79%, 25-year): max loan ≈ $547,000
- Plus 10% down ($61,000): max purchase price ≈ $608,000
This is meaningfully less than what the gross income would suggest, because the stress test forces qualification at 6.79% instead of the actual 4.79% contract rate. If the contract rate dropped from 4.79% to 3.99% (likely in late 2026 if BoC keeps cutting), the same household qualifies for ~$650,000.
Fixed vs variable in 2026
Short answer: Variable rates are tied to the Bank of Canada overnight rate, currently in a cutting cycle that started June 2024. If BoC continues cutting, variable beats fixed by 0.5-1.5% over a 5-year horizon. Fixed locks the rate for the term — peace of mind at a small premium. For buyers with tight budgets who can't absorb a rate shock at renewal, fixed is the safer call. For buyers with breathing room and faith in BoC's cutting cycle, variable has the math advantage.

Historical performance (data through 2024): variable beats fixed roughly 70% of the time on a 5-year horizon — but the 2022-2024 rate-shock period was a brutal exception that hurt variable-rate borrowers. Going forward in 2026, the math leans variable IF you believe in further BoC cuts. A mortgage broker (free, paid by the lender) can model both scenarios for your specific case.
Frequently asked questions
Is the mortgage stress test still required in 2026?
Yes. OSFI confirmed in March 2024 that the stress test remains in place for all federally regulated lenders (Big 5 banks, most credit unions). Provincially regulated credit unions and mortgage investment corporations (MICs) are not subject to the stress test but their rates are typically 0.5-1.5% higher.
Can newcomers to Canada get a mortgage without Canadian credit history?
Yes. All major banks run newcomer mortgage programs that accept foreign credit reports from CIBIL (India), Schufa (Germany), Experian (UK/US), and others. Typical requirements: minimum 6 months in Canada, valid PR or qualifying work permit, employment in Canada, 5-10% down payment, 3-month Canadian bank statements.
How much CMHC insurance will I pay on a $600,000 home with 5% down?
$600,000 home × 5% down = $30,000 down. Loan = $570,000. CMHC premium at 4.00% = $22,800. Total financed = $592,800. The premium is amortized over the loan, adding about $130/month to payment over 25 years at 4.79%.
What is the First Home Savings Account (FHSA)?
A registered account introduced in 2023 for first-time home buyers. Contributions up to $8,000/year (max $40,000 lifetime) are tax-deductible like an RRSP, AND withdrawals for a home purchase are tax-free like a TFSA. Couples can combine for $80,000. More efficient than the Home Buyers' Plan for most newcomers because the tax savings stack.
What's the difference between a mortgage broker and a bank?
A mortgage broker shops multiple lenders simultaneously to find your best rate, typically scoring 0.1-0.5% lower than the bank's posted rate. The broker is paid commission by the lender, so the rate you get is identical to what the lender would quote directly. A bank only offers its own products. For most borrowers, a broker is the right call.
Can I break my mortgage early if rates drop?
Yes, but it costs. Fixed-rate mortgages have an Interest Rate Differential (IRD) penalty of 3-5% of the loan ($15K-$25K on a $500K mortgage). Variable-rate mortgages typically have a 3-month interest penalty (~$3K-$6K). Break-even math: only worth it if rates drop 1.5%+ AND you have at least 18 months left in the term.
How does the Canadian mortgage stress test differ from the US qualifying rate?
The US has no equivalent. American lenders qualify borrowers at the actual contract rate (or sometimes a slight buffer). Canada's stress test was introduced in 2018 specifically to cool an overheating housing market and protect borrowers from rate shocks at renewal — because Canadian mortgages renew every 1-5 years while US mortgages typically lock for 30.
Is mortgage interest tax-deductible in Canada?
No — unless the mortgage is on a property you rent out (in which case interest is deductible against rental income). For owner-occupied homes, mortgage interest is NOT tax-deductible in Canada. This is opposite to the US, where mortgage interest on a primary residence is deductible.
