Living in Unionville, Markham

The short answer

Unionville is the postcard version of Markham. A preserved nineteenth century main street, a pond, mature trees and a GO station within reach of a good part of the neighbourhood. That combination is rare in the northern GTA and the market prices it accordingly.

If you want one line: Unionville is where you pay for setting and reputation, not for square footage. Buyers who want the most house per dollar almost always end up further north or east.

Where the neighbourhood actually begins and ends

People use Unionville loosely. In practice there are three distinct pockets and they behave differently.

The historic core runs along Main Street Unionville and the streets immediately around it, down to Toogood Pond. This is the part everyone means when they say Unionville. Heritage character, tight lots, very little turnover.

The mature residential belt sits north and east of the core. Mostly detached homes from the 1970s through the 1990s on generous lots, with the tree canopy that came with them. This is the volume of the market and where most family purchases happen.

The Highway 7 corridor on the south edge is newer and denser: mid-rise condos, stacked towns and newer freehold townhomes. Prices here track Downtown Markham more closely than they track the historic core, which is worth knowing before you compare two listings that share a postal code.

What homes cost

From April to June 2026 TRREB recorded 159 sales in Unionville with a median of $735,000 across all property types. That median is pulled down by condo apartments, which made up 96 of the sales, so use the property type rows in the table above.

The spread in this market is wide. In the same quarter the condo apartment median was about $572,000 and the detached median about $1,625,000, so a single average price tells you very little here.

Two things move price more than anything else in Unionville. The first is lot width and mature trees. The second is walking distance to Main Street. A house four streets further out with the same floor plan trades meaningfully lower and buyers who understand that can find real value.

Schools

Unionville High School is the main YRDSB secondary option and it runs a regional arts programme that admits students by audition from across York Region. That programme is a genuine draw and it does affect demand for housing in the catchment.

Bill Crothers Secondary School, also in Unionville, is a sport focused school with its own application process rather than a residential catchment.

Elementary options include both YRDSB and YCDSB schools. Catchment boundaries are reviewed periodically and they do change, so confirm the boundary for the specific address rather than the neighbourhood. Never buy a house on the assumption that a boundary will hold.

Parks, the pond and daily life

Toogood Pond is the anchor. Trails, a boardwalk and the kind of green space people actually use on a Tuesday evening rather than only on weekends. The Rouge valley system runs nearby and connects into a broader trail network.

Main Street carries the restaurants, cafes and the Varley Art Gallery. Day to day grocery and big box shopping happens off the neighbourhood, mostly along Highway 7 and Kennedy Road.

The honest trade-off: Main Street is a destination. On festival weekends and through the summer the traffic and parking spill onto the residential streets around it. If you value absolute quiet, look at the mature belt further north rather than the core.

Transit and the commute

Unionville GO sits on the Stouffville line and runs into Union Station. For a downtown commuter this is the single strongest argument for the neighbourhood and it is why the streets within walking distance of the station hold their value.

Scheduled weekday morning trains take 41 minutes from Unionville GO to Union Station (GO Transit timetable, September 2026).

Highway 7 carries YRT and Viva bus rapid transit across the top of the neighbourhood, which connects west toward Richmond Hill and Vaughan and east toward Cornell. Highway 407 is a short drive. Highway 404 is the usual route south.

Driving downtown in rush hour is not a serious plan. Most people who work in the core take the train.

Homes for sale in Unionville

What comes up for sale in Unionville usually falls into one of a few types: detached houses on mature lots in the historic core and the belt north and east, heritage homes on and near Main Street, executive townhomes and mid-rise condos toward Downtown Markham. The heritage homes on Main Street itself rarely come up for sale, while the mature belt and the Highway 7 corridor see more regular turnover.

From April to June 2026, TRREB recorded a detached median of about $1,625,000, a freehold townhouse median of about $1,295,000 on a small sample of 5 sales, a condo townhouse median of about $829,000 and a condo apartment median of about $572,000. The all property types median across 159 sales was $735,000.

Downsizing in Unionville

Unionville offers one of the widest downsizing ranges in Markham, from executive townhomes down to mid-rise condos toward Downtown Markham. From April to June 2026 the detached median was about $1,625,000 while the condo apartment median was about $572,000, a gap of well over $1,000,000 for buyers trading a mature-lot house for a smaller unit closer to Highway 7.

The historic core and the mature belt hold most of the freehold townhouse stock, with a median of about $1,295,000 on 5 sales in the same period, which suits downsizers who want to stay in a house rather than a condo but no longer need the largest lot. Those who prioritize the Main Street setting and walkability to Unionville GO tend to look at the Highway 7 corridor condos first, since prices there track Downtown Markham rather than the historic core.

What Unionville offers

Unionville offers heritage homes and character streets around historic Main Street, mature lots and condos and townhomes toward Downtown Markham. Unionville GO is there for the commute downtown. Its character and setting come at a premium in TRREB’s price figures.

It offers less in the way of maximum square footage, brand new builds or quiet on a summer weekend near Main Street. For those, look at Wismer, Greensborough or Angus Glen.
