Markham Neighbourhoods Guide: Unionville, Cornell, Berczy Village, Cathedraltown and More

Markham is easy to describe in numbers and harder to describe in feel, because it contains several towns' worth of character inside one city. There are two historic main streets, planned communities built around laneways and parks, a fast-growing downtown and large established subdivisions. If you are relocating or moving up within York Region, knowing the differences between these areas helps you focus your search on homes that fit your commute, schools and lifestyle. This guide goes deeper on Markham alone; if you are still choosing between cities, start with our York Region neighbourhood comparison.

Markham at a glance

Markham had 338,503 residents in the 2021 Census, up 2.9% from 2016 (Statistics Canada, 2021 Census, accessed October 2026). That makes it the most populous municipality in York Region. It is crossed by Highway 404 and Highway 407, and it is served by the GO Stouffville line, which includes Unionville, Markham and Mount Joy stations within the city (Stouffville line overview, based on GO Transit station list, accessed October 2026). Like the rest of the region, Markham has no municipal land transfer tax.

Unionville

Unionville's heritage Main Street, with its restored buildings, shops, restaurants and Toogood Pond nearby, is one of the best-known streetscapes in York Region. Around it are established neighbourhoods of detached homes, many on larger lots, along with newer infill. Unionville GO Station sits to the south near Kennedy Road and Enterprise Boulevard. The area is popular with families, partly for its parks and partly for its school reputation; always confirm the current school boundary for a specific address with the York Region District School Board rather than relying on a listing. Parts of Unionville are in a heritage conservation district, so exterior changes may need heritage approval.

Markham Village

Markham Village, centred on Main Street Markham north of Highway 7, is the city's other historic core. It has a mix of century homes, mid-century bungalows and newer subdivisions, plus Markham GO Station and the Markham Museum nearby. Buyers who like walkable main-street living but want a different feel from Unionville often compare the two. As with Unionville, heritage designations can apply close to Main Street.

Cornell

Cornell, in Markham's east end near Highway 7 and Ninth Line, is a planned community built on new-urbanist principles: rear laneways with garages, front porches facing the street, and parks within walking distance. Housing ranges from townhouses and semis to detached homes and some mid-rise buildings. The Markham Stouffville Hospital and Cornell Community Centre are close by, and Mount Joy GO Station is a short drive away. Cornell tends to appeal to buyers who want a newer home and a neighbourhood that encourages walking. Laneway homes often have smaller yards, so check outdoor space carefully.

Berczy Village and Cathedraltown

Berczy Village, north of Major Mackenzie Drive between Kennedy and Warden, grew from the late 1990s and 2000s and is mainly detached and semi-detached family housing, with parks and schools woven through the subdivision. Cathedraltown, to the west near Woodbine Avenue, is a smaller planned community built around the Cathedral of the Transfiguration, with a mix of townhouses and detached homes. Both are a short drive from Highway 404, which suits commuters heading south.

Markham Centre (downtown Markham)

Around Highway 7 and Warden Avenue, Markham Centre is the city's planned downtown, with high-rise condominiums, offices, shops and the Viva Purple rapidway along Highway 7. It suits buyers who want a condo with transit access and walkable shops. Because much of the stock is new or pre-construction, read the condo documents and fee history carefully and check Tarion and HCRA information for the builder; our post on how to check a builder's reputation in Ontario explains how.

Thornhill (Markham side) and the south

East of Yonge Street, Markham's share of Thornhill includes established neighbourhoods with mature trees, ravines and homes from the 1960s to the 1990s. Further east, areas such as Milliken and Armadale have a mix of older subdivisions and newer townhouse projects close to the Toronto border. These south-end areas can offer shorter drives into Toronto, which some commuters value more than newer construction.

What to check before you buy in Markham

• Heritage status: ask whether the property is designated or within a heritage district if it is near Unionville or Markham Village.
• School boundaries: confirm with the school board for the exact address.
• Development nearby: check active applications on the city's website, especially near Highway 7 and the 404.
• Parking and laneways: in planned communities, confirm garage, driveway and visitor parking arrangements.
• Carrying costs: review the actual tax bill and, for condos, the status certificate.

Every area has trade-offs, and prices move with the wider market. The goal is to match the neighbourhood to your daily life. If you are preparing to sell a Markham home before buying, our post on preparing a Markham home for sale covers the selling side.

Commuting from Markham

Most Markham residents commute by car, using Highway 404, Highway 407 (a toll road) or arterial roads such as Kennedy, Warden and Woodbine. GO Stouffville line trains serve Unionville, Markham and Mount Joy, and Viva Purple buses run along Highway 7. The best way to compare neighbourhoods is to test the commute you will actually make, at the time you will actually make it, before you firm up an offer. If 407 tolls are part of the plan, include them in your monthly budget.

A final tip: Markham is large enough that two homes with the same price can offer very different daily lives. Spend a Saturday driving between Unionville, Cornell and Berczy Village, stop for coffee on each main street and walk the parks. The neighbourhood that feels right on an ordinary afternoon is usually a better guide than any ranking.
