How Much House Can I Afford on a $100K Salary in Canada? (2026 Math)

A $100,000 salary in Canada buys a very different house in 2026 depending on your debts, down payment, and city. The honest answer is somewhere between $385,000 and $625,000 — and this guide shows you exactly where on that spectrum you'll land.

We'll work through the actual math the bank uses (not the rule-of-thumb shortcuts), then show you the levers to move yourself up the range.

The Two Numbers Banks Actually Care About

Lenders qualify you based on two debt-service ratios:

GDS (Gross Debt Service)

Your housing costs as a % of gross income. The cap is typically 39% for insured mortgages.

Housing costs include:

• Mortgage principal + interest (calculated at the qualifying rate)
• Property taxes (annual ÷ 12)
• Heating cost ($100-150/month assumed)
• 50% of condo fees if applicable

TDS (Total Debt Service)

GDS + all other monthly debt payments, capped at 44% for insured mortgages.

Other debts that count:

• Credit card minimums (3% of balance)
• Car loan or lease payment
• Student loans
• Personal lines of credit
• Child support / spousal support

The Stress Test (Required for All Federal Lenders)

In 2026, you must qualify at the greater of 5.25% or your contract rate + 2%.

If your contract rate is 4.20%, you qualify at 6.20%. This is the rate used in the GDS/TDS calculation, not your actual contract rate.

Baseline: $100K, No Debt, Toronto

Let's work a clean example.

• Gross income: $100,000/year ($8,333/month)
• GDS cap: 39% × $8,333 = $3,250/month for housing
• No other debts, so TDS isn't binding
• Property tax estimate: ~1.0% of purchase price annually (Toronto: $4,500/year on a $450K home = $375/month)
• Heating: $125/month
• Qualifying rate: 6.20%

Working backwards from $3,250/month housing:

• Subtract $375 property tax + $125 heating = $2,750/month for principal+interest
• At 6.20% on a 25-year amortization, $2,750/month supports a mortgage of ~$420,000

With 20% down (uninsured), the maximum purchase price is ~$525,000.

With 5% down (insured), the maximum purchase price is ~$442,000 (because higher LTV = higher property tax/payment ratio, and the 5% only buys you 5% of price).

So a $100K-earning Torontonian with no debt buys roughly $440K-$525K depending on down payment, in 2026.

How Debt Crushes Your Capacity

Add a $400/month car payment to the same applicant:

• TDS becomes the binding constraint: 44% × $8,333 = $3,667/month for all debt service
• Subtract $400 car = $3,267/month available for housing
• Subtract $375 property tax + $125 heating = $2,767/month for P+I
• Mortgage capacity: ~$422,000 — basically unchanged

But add a $400 car plus $300/month in credit card minimums (on a $10K balance):

• Available for housing: $3,667 - $400 - $300 = $2,967/month
• For P+I: $2,967 - $500 = $2,467/month
• Mortgage capacity: ~$377,000

That $700/month in consumer debt cost you $45K of mortgage capacity. Pay off the cards before you apply.

How Down Payment Changes the Game

Same $100K applicant, no debt, in Toronto, varying down payment:

The math floor (your mortgage capacity) is roughly the same in all cases — the down payment just determines how much house that mortgage buys.

This is why FHSA + RRSP HBP stacking matters so much for first-time buyers. We covered the full first-time buyer stack here.

City-by-City: What $100K Actually Buys

Same applicant, no debt, 20% down, in different markets:

Toronto

• $525,000 max purchase
• Reality: condos in Etobicoke, Scarborough, suburban 905 belt
• Detached homes essentially out of reach in the city proper

Vancouver

• $510,000 max purchase (slightly lower due to higher property taxes)
• Reality: studio/1BR condo in Burnaby, New West, Surrey
• Detached impossible

Calgary

• $560,000 max purchase (lower property tax + heating helps)
• Reality: townhouse in inner suburbs, condo in the core
• Detached homes available in Beltline-adjacent and outer suburbs

Ottawa

• $545,000 max purchase
• Reality: townhouse in Barrhaven, Kanata, Orleans
• Detached achievable in outer Ottawa Valley

Halifax

• $565,000 max purchase
• Reality: detached in Dartmouth, Bedford, suburbs
• Excellent value compared to Ontario/BC

How a Couple Stacks Up

Two $100K earners (combined $200K) in Toronto, no debt, 20% down:

• GDS cap: 39% × $16,667 = $6,500/month for housing
• Subtract ~$700 property tax + $125 heating = $5,675 for P+I
• At 6.20% qualifying rate: mortgage capacity ~$870,000
• Max purchase: ~$1,090,000 (with 20% down)

Two $100K earners can comfortably buy a $1.1M home in Toronto in 2026. This is the math behind why dual-income households dominate the market.

How to Move Up the Range

1. Pay off all consumer debt before applying — the single biggest move
2. Maximize your down payment through FHSA + HBP stacking
3. Bring a 30-year amortization into play (only available to first-time buyers on new builds in 2026) — adds ~10% to capacity
4. Negotiate the lowest contract rate you can get — every 0.25% lower drops your qualifying rate too
5. Consider a credit union if you're at provincial jurisdiction (no OSFI stress test in some cases)
6. Bring a co-signer with strong income if you're close to the line
