Thornhill is served by the York Region District School Board and the York Catholic District School Board, along with French-language boards. Boundaries and capacity change as new subdivisions open, so we always check the board's school locator for a specific address before you make an offer.
Thornhill isn't one market. In 2026 Q2, homes in the Markham-side Thornhill community sold at 93% of asking after 46 days, while Aileen-Willowbrook sold at 101% in 27 days. We pull recent sales for the exact pocket before we write an offer.
With 175 sales on the Vaughan side and 114 on the Markham side in 2026 Q2, buyers have choice. Pricing against the right comparables, in your community and on your side of Yonge, is what moves a Thornhill listing. Our plan starts with current TRREB data for your street.
Many Thornhill families start in a condo near Promenade or along Yonge and move up within the area. Vaughan's benchmark apartment was $504,900 in October 2026, and Markham's was $510,500. Our HOMEBOUND Method maps the move: what your condo will sell for, what you can afford next, and whether to buy first or sell first.
Both. Thornhill west of Yonge Street is in Vaughan, and Thornhill east of Yonge is in Markham. TRREB reports each side by community.
It depends on the community. In 2026 Q2, averages ranged from $963,936 in Crestwood-Springfarm-Yorkhill to $1,771,300 in Uplands on the Vaughan side, and from $1,016,214 in Aileen-Willowbrook to $1,275,833 in German Mills on the Markham side, excluding Bayview Glen (TRREB).
In 2026 Q2, days on market ranged from 20 in Glen Shields and German Mills to 63 in Bayview Glen. Most communities sold in 27 to 46 days (TRREB).
In some pockets. The Markham-side Thornhill community sold at 93% of asking in 2026 Q2, while Aileen-Willowbrook sold at 101% (TRREB). Negotiating room depends on the exact community.
It depends on your equity, financing and how fast your condo is likely to sell. Condo apartments averaged 42 days on market in Vaughan and 34 in Markham in October 2026. We plan the timing with you before you list.
