Markham's 2026 market is the GTA's most tech-anchored 905 city, with an average detached price near $1.72M, semis at $1.21M, freehold towns at $1.08M, and condos averaging $725,000. Buyers pick Markham for top-tier York Region public schools, a deep tech employment base (IBM, AMD, Honeywell, Huawei), the Unionville-Markville mature core, and the Yonge North Subway Extension under construction. This guide walks from Unionville to Markham Village with real prices and 2026 offer strategy.
Markham in 2026 — what the data shows
Markham is reported by TRREB's York region and shows roughly 2,800 active listings in March 2026, average DOM of 29 for freehold and 44 for condos. Sales-to-new-listings ratio near 50% — balanced market with seller-favoured pockets at the high end of school catchments.
Markham's appeal is concentrated: top-quartile YRDSB schools (Bayview SS, Pierre Elliott Trudeau HS, Unionville HS), the largest concentration of Asian-Canadian businesses in the GTA, and a tech employment cluster around the Markham Innovation Exchange and Highway 404 corridor. The Yonge North Subway Extension is under construction from Finch to Hwy 7 in Richmond Hill, with future Markham connections under planning.
Median household income (2021 Census, indexed to 2026) is approximately $138,000. With the OSFI stress test qualifying at 6.69%, the $1.72M average detached requires roughly $258,000 household income at 20% down — a stretch for single-income buyers.

Unionville to Markham Village — pocket breakdown
Markham divides into five recognizable areas with distinct price bands.
Unionville
Unionville is the premium heritage core, with detached pricing $2.05M-$3.5M+ on lots ranging 50-90 feet. Main Street Unionville is a heritage-conservation village with restaurants, boutiques, and the Markham Theatre. Catchment includes Unionville HS (top-15 provincially) and William Berczy PS. The Toogood Pond walking trail and proximity to Markville Mall add lifestyle value.
Markham Village and Cornell
Markham Village is the historic main-street community along Highway 7 east of Markville Mall. Detached homes run $1.45M-$1.85M with heritage character. Cornell, the newer planned community east of Box Grove, is family-suburb-modern: $1.55M-$1.95M for detached, $985k-$1.15M for towns. Cornell hosts Markham-Stouffville Hospital and Cornell Community Centre.
Berczy Village and Wismer
Berczy and Wismer are 2000s-built family suburbs north of Major Mackenzie. Detached $1.5M-$1.85M for 2-storey 4-bed. Strong catchment includes Pierre Elliott Trudeau HS (top YRDSB option) and Castlemore PS. Berczy is denser townhouse stock; Wismer is detached-dominant.
Cathedraltown and Cachet
Cathedraltown is a luxury master-planned community near the Cathedral of the Transfiguration. Detached estate homes $1.85M-$3.2M on larger lots. Cachet, east of Woodbine Avenue, is a 1990s-2000s premium pocket with similar pricing.

Markham's property tax is among the GTA's lowest because of strong commercial-industrial base — Markham Innovation Exchange, IBM Canada HQ, AMD's Canadian presence, Honeywell, Huawei Canada, and the Hwy 404 corridor.
Transit, employment, and schools
Markham's transit is GO Train (Stouffville Line) and YRT Viva BRT-anchored. GO Stouffville stations include Unionville, Centennial, and Markham GO, with peak-trip Union Station times of 38-52 minutes. YRT Viva BRT serves Highway 7 east-west and Yonge north-south. The Yonge North Subway Extension to Hwy 7 in Richmond Hill is under construction with completion targeted 2031, and future Markham extensions are in EA review.
Major employers: IBM Canada (Markham HQ, 4,500+ staff), AMD, Honeywell, Huawei Canada R&D, Markham Stouffville Hospital, ASUS, Motorola Solutions, and dozens of mid-cap tech firms in the Markham Innovation Exchange. The Hwy 404 corridor anchors logistics and distribution.
Schools split between YRDSB and York Catholic. YRDSB's Bayview SS, Unionville HS, and Pierre Elliott Trudeau HS are consistently Ontario's top public schools by Fraser Institute rankings. Private options include Toronto Montessori School (markham campus) and Country Day School.
Investment, ARUs, and rental yield
Markham rents (Rentals.ca + CMHC, Q1 2026):
- 1-bed Unionville/Markham GO area condo: $2,195-$2,395
- 2-bed Markham condo: $2,795-$3,200
- 3-bed Berczy townhouse: $3,150-$3,500

Cap rates: condos 3.6-4.2%, detached 2.6-3.2%. Markham's 2024 ARU bylaw permits up to three units per residential lot. The city has strict heritage-overlay rules in Unionville and Markham Village that affect ARU eligibility and exterior modifications.
The RTA governs every tenancy with the 2026 rent guideline of 2.5%. Markham investors often target Berczy and Cornell newer detached for legal basement suite cash-flow plays — these areas have fewer heritage constraints.

Offer strategy and how to win in 2026
Markham's offer dynamics: roughly 47% of freehold listings sold over asking in Q1 2026, concentrated in Unionville, Berczy/Wismer, and Bayview Glen. Condo listings sold over asking only 23% of the time.
- Pre-approval with 90-120 day rate hold — Markham buyers often need higher pre-approvals than other 905 cities given the $1.72M average
- Status certificate review on every condo offer; Unionville-area condos in mature buildings often have looming roof and elevator capital projects
- School-catchment due diligence: YRDSB boundary reviews can shift Bayview SS, Unionville HS, and PET HS catchments — verify with the YRDSB tool before firm
- Heritage overlay check: Unionville and Markham Village heritage rules limit exterior modifications and ARU additions
- Watch sub-pocket pricing: within Berczy, properties zoned for PET HS trade 8-12% above otherwise comparable homes in adjacent catchments

Frequently asked questions
Why are Markham public schools so highly ranked?
Markham public schools dominate the Fraser Institute rankings because of a combination of strong family education focus (particularly in the city's Asian-Canadian communities), well-resourced YRDSB programs (IB, AP, French immersion), and high parental engagement. Bayview SS, Unionville HS, and Pierre Elliott Trudeau HS routinely score in Ontario's top 15 of 749 secondary schools. School catchment drives measurable price premiums — 8-12% within PET HS boundary versus adjacent catchments. The premium has held through every market cycle since 2010, making schools the dominant resale-value driver in Markham.
What's the difference between Unionville and Markham Village?
Both are heritage main-street villages, but Unionville is the higher-priced premium pocket with detached homes $2.05M-$3.5M+ on larger lots and direct catchment to Unionville HS. Markham Village is the historic core along Hwy 7 east of Markville Mall, with detached $1.45M-$1.85M. Both have heritage-conservation overlay limiting exterior modifications. Unionville's Main Street is more polished (restaurants, boutiques, Markham Theatre); Markham Village retains a more local-services character. Unionville's Toogood Pond is a major lifestyle amenity; Markham Village has the Markham Museum and Cornell Community Centre nearby.
How does the Yonge North Subway Extension affect Markham?
The Yonge North Subway Extension (YNSE) is under construction from Finch (current Line 1 terminus) to Hwy 7 in Richmond Hill, targeted to open in 2031. While Markham doesn't directly receive YNSE stations, the line will dramatically improve connectivity for north-Markham residents commuting to downtown Toronto. Future Markham subway extensions (Cummer station and east to Markham Centre) are under EA review. Bayview Glen and west-Markham areas closest to future stations are seeing 4-6% premiums build into land values. End-users without subway commute needs may find better value east in Cornell and Box Grove.
Can I add a basement suite to my Unionville home?
Yes, but Unionville's heritage-conservation overlay imposes additional constraints. Under Markham's 2024 ARU bylaw (Bill 23-aligned), up to three units per residential lot are permitted in principle. However, heritage-area properties require Heritage Permit Approval for any exterior modifications including separate entrances, window enlargements for egress, and accessory structure additions. Interior basement suites with existing egress and no exterior changes are typically faster to permit. Garden suites in heritage areas face the most restrictions. Budget $40-70k for a code-compliant legal basement suite with proper fire separation and egress.
What's the property tax bill in Markham?
Markham's 2026 blended residential property tax rate (City + York Region + education) is approximately 0.73%, producing about $12,560/year on a $1.72M detached. That makes Markham one of the GTA's lower-tax cities thanks to a strong commercial-industrial tax base (IBM, AMD, Honeywell, Huawei, the broader 404 corridor). Bills are issued quarterly with monthly pre-authorized payment. Compare to Vaughan (0.69%), Mississauga (0.84%), Brampton (1.05%), and Toronto (0.72%). The municipal portion funds parks, libraries, transit, and roads; the regional portion funds policing, water, and social services.
