See how it works

Durham Region — stretching from Pickering at the Toronto border east through Ajax, Whitby, Oshawa, and Clarington — is one of Ontario's most active mortgage markets. The region's role as a Toronto commuter belt, combined with home prices that are meaningfully more affordable than Toronto proper, makes it the destination of choice for first-time buyers and growing families across the GTA. This guide covers the full mortgage landscape for Durham Region buyers in 2025.

Durham Region Home Prices: Context for Mortgage Planning

Prices vary significantly across Durham Region depending on location, proximity to GO Transit, and community type:

These ranges are for detached homes. Condos and townhouses are available at meaningfully lower price points across all communities.

Mortgage Stress Test in Durham Region

All federally regulated mortgage lenders apply the stress test: you must qualify at the higher of your contract rate + 2%, or 5.25%. In 2025, with rates in the 4.3%–5.00% range, this means qualifying at approximately 6.3%–7.00%.

This has a concrete impact on maximum borrowing power. At a qualifying rate of 6.5% on a 25-year amortization, a household qualifying income of $150,000 might support a mortgage of approximately $750,000–$800,000, depending on other debts.

Stress Test Navigation: Durham Region residents who just miss qualifying at a chartered bank (due to the stress test) have several alternatives: credit unions (provincially regulated, may apply the stress test differently), B-lenders (higher rates but less strict qualifying), and mortgage brokers who can find the best fit across dozens of lenders.

CMHC Insurance: The Math for Durham Region Buyers

If you put less than 200% down, CMHC mortgage default insurance is required. Here's what it costs at typical Durham Region price points:

Purchase Price5% DownCMHC PremiumTotal Mortgage
$700,000$35,000$26,600$691,600
$800,000$40,000$30,400$790,400
$1,000,000$50,000$38,000$988,000

Note: CMHC insurance is only available on purchases up to $1.5 million (rule updated late 2024). Purchases above that threshold require a 200% minimum down payment with no CMHC option.

Ontario Land Transfer Tax in Durham Region

None of Durham Region's municipalities levy a municipal land transfer tax. Buyers across Pickering, Ajax, Whitby, Oshawa, Clarington, Scugog, Uxbridge, and Brock pay only the provincial LTT. At $800,000 (a common Durham Region transaction): gross LTT is $13,475; after the first-time buyer rebate ($4,000) it's $9,475.

By contrast, a Toronto buyer at the same price would pay approximately $26,475 in combined provincial and municipal LTT — nearly double the Durham Region amount.

GO Transit and Mortgage Qualification

For many Durham Region buyers who commute to Toronto via GO Transit, the GO pass cost is a real household expense that mortgage advisors should factor into budget planning. Monthly GO passes from Durham communities to Union Station:

At the household level, two GO commuters could add $540–$660/month to the budget. Factor this into your maximum comfortable mortgage payment calculation.

Fixed vs. Variable: Durham Region Buyer Perspective

Durham Region buyers face the same rate decision as all Canadians. In 2025, most first-time buyers are choosing fixed rates for payment certainty given the size of Durham Region mortgages. Key considerations:
