Ontario Mortgage Affordability Calculator (Updated August 2026)

Updated

Maximum Home Price

How much house can you afford in Ontario?

Ontario’s provincial MLS HPI composite benchmark was $746,800 in July 2026, down 3.8% year-over-year, with apartments (-6.8%) and townhouses (-6.0%) falling faster than single-family homes (-3.6%). The most recent full sales breakdown (March 2026) put the average home price at $811,868 (-4.8% YoY). Affordability varies more across Ontario than perhaps any other province — from well under $400,000 in Northern Ontario to over $1 million in the GTA, where the average has actually risen to $1,003,956.

Ontario affordability by income and region

Estimates based on 20% down payment, a 4.5% contract rate (stress tested at 6.5%), 25-year amortization, and no other debts. These are ballpark figures — use the calculator above for your exact numbers.

Ontario land transfer tax impact on affordability

Ontario’s LTT is a sliding scale. First-time buyers get a rebate of up to $4,000. Toronto buyers pay a second municipal LTT (see Toronto affordability).

Home PriceOntario LTTAfter FTB Rebate% of Down Payment (10%)
$400,000$4,475$47511.2%
$600,000$8,475$4,47514.1%
$811,868 (ON avg)$12,451$8,45115.3%
$1,003,956 (GTA avg)$16,054$12,05416.0%

Ontario property tax rates vary widely

Higher property taxes reduce your maximum affordable home price because lenders include them in the GDS ratio.

CityProperty Tax RateAnnual Tax on $600K Home
Toronto0.67%$4,020
Ottawa1.02%$6,120
Hamilton1.28%$7,680
London1.34%$8,040
Windsor1.81%$10,860

A Windsor homeowner pays 2.7x more property tax than a Toronto homeowner on the same-priced home — significantly reducing borrowing capacity.

Why the mortgage stress test hits Ontario buyers harder than most provinces

The federal stress test qualifies you at the higher of your contract rate plus 2%, or 5.25% — currently 6.5% for most Ontario buyers on a 4.5% rate. That 2-point buffer matters more in dollar terms as prices rise: on a $400,000 home it adds roughly $47,000 to the income needed to qualify; on the GTA average of $1,003,956, the same 2-point buffer adds closer to $118,000 in required income. Since Ontario has both Canada’s highest average price and one of its lowest average incomes relative to that price, the stress test effectively removes more GTA buyers from the market than it does in lower-priced provinces like Alberta or Manitoba, where the same 2-point buffer is a smaller share of the qualifying income.

Tips for Ontario homebuyers

  1. Consider where, not just how much — A $100K income buys comfortably in Northern Ontario but doesn’t clear the bar for most GTA condos
  2. Prices are still falling in most segments — Apartments (-6.8%) and townhouses (-6.0%) are down more than single-family homes (-3.6%), so condo buyers have more negotiating room
  3. Property tax rates vary 3x — Factor this into lender qualification, not just purchase price
  4. First-time buyer LTT rebate — Save up to $4,000 provincial (plus $4,475 in Toronto)
  5. Compare mortgage rates — On the $811,868 provincial average, 0.25% saves roughly $125/month

CMHC insurance5% minimum down on homes under $1.5MCommon for condos and townhomes
GST/HST New Housing RebatePartial HST rebate on new builds13% HST applies in Ontario

Ontario’s LTT rebate is most valuable in smaller Ontario cities where home prices overlap with the rebate threshold ($368,000). In the GTA, the rebate covers a small fraction of the LTT, but it’s still meaningful free money.

How existing debt affects the income you need

The TDS ratio (44% limit) means existing debts directly reduce your borrowing capacity.

Monthly DebtAdditional Income Needed
$300 (minimum credit card payments)+$8,200/year
$500 (car payment)+$13,600/year
$800 (car + student loan)+$21,800/year
$1,200 (car + student loan + line of credit)+$32,700/year

Example: Buying in Ottawa ($641,436, 20% down) with a $500/month car payment requires roughly $156,000 instead of $142,484.
