Where this is: Centred on Main Street Unionville, running roughly between Highway 7 and Sixteenth Avenue, east of Warden and west of McCowan.
Unionville is the part of Markham most people picture first. Main Street Unionville is a preserved nineteenth century streetscape with a heritage conservation district designation, which means alterations to properties inside it face a level of review that does not apply elsewhere in the city. That single fact shapes more Unionville transactions than any other.
The area around the old village has been built out in waves since, so a buyer here is really choosing between several quite different products under one name. A heritage property a short walk from Toogood Pond, a large lot detached home from the 1980s further north and a new condominium in Downtown Markham off Enterprise Boulevard are all sold as Unionville. They behave differently on resale, they attract different buyers and they carry very different carrying costs.
Demand is consistently strong, driven heavily by school catchment and by the village itself as an amenity. That strength cuts both ways for a seller: competition among buyers is real, but so is buyer sophistication, and pricing strategy in Unionville is rarely a matter of simply listing high.

What to ask an agent about Unionville

- If the property sits inside the Unionville Heritage Conservation District, what alterations would actually require heritage permit approval, and how long does that process typically take?
- How does resale behaviour differ between a Downtown Markham condominium and a detached home a few streets away, given both are marketed as Unionville?
- Which specific school catchment does this address fall into, and can you show me the board boundary rather than a real estate listing description of it?
