Thornhill Homes for Sale — Vaughan Side
The Yonge-Steeles corridor, where Vaughan meets North York.
Thornhill straddles the Steeles border — the south half belongs to Markham, the north half to Vaughan. This page covers the Vaughan side: Uplands, Beverley Glen, and Crestwood-Springfarm-Yorkhill, the three TRREB communities that together form what locals just call "Vaughan Thornhill".
The market here is different from the rest of Vaughan. Housing leans mid-century (1960s–80s detached on 50–70 ft lots) with a strong custom-rebuild cycle in the last decade. The area skews older and more Jewish than other Vaughan communities, with the UJA, Promenade Mall, and several of the GTA's best Kosher restaurants anchoring the community. Move-up family buyers from North York routinely cross into Vaughan Thornhill for more house and a slightly better tax rate.
Typical detached range is $1.6M–$2.4M for established homes, $2.5M–$3.5M+ for recent custom rebuilds. Condo / townhouse inventory on the Yonge corridor offers more accessible entry points.

Which side of Thornhill should you buy on?
The decision between Vaughan-Thornhill and Markham-Thornhill comes down to three things: property tax, school catchment, and lot size. Vaughan's property tax rate is meaningfully lower than Markham's (roughly 0.66% vs 0.78% of assessed value in 2026) — on a $2M home that's a $2,400/year difference, every year. Schools swing the other way: Markham's English-public secondary options (Thornlea, St Robert) are slightly stronger than Vaughan Thornhill's public equivalents; though private options are abundant on both sides. Lot sizes favour the Vaughan side on average, with more 60–70 ft frontage detached inventory.
For most move-up buyers the tax-savings + lot-size combination makes Vaughan Thornhill the better long-term pick. Markham Thornhill remains strong for public-school-focused families.
