Introduction

Thornhill is a community on both sides of Yonge Street, just north of Toronto. The west side is in the City of Vaughan and the east side is in the City of Markham. Thornhill has had no municipal government of its own since 1971, when the old police village was divided between the two.

The community grew along Yonge Street, which was cleared north from Toronto in the 1790s. Benjamin Thorne arrived in 1820 and came to run a grist mill, a sawmill and a tannery. The settlement, first known as Thorne's Mills and then Thorne's Hill, received a post office in 1829 under the name Thornhill. In 1896, the Metropolitan Radial Railway reached Thornhill, and it became possible to live there and work in Toronto.

Real estate overview

Thornhill has a historic village core on Yonge Street, neighbourhoods of houses on both sides, and apartment and condominium buildings along Yonge Street and other main roads.

The Yonge North Subway Extension will take TTC Line 1 about eight kilometres north from Finch Station, with new stations planned at Steeles, Clark, Royal Orchard, Bridge and High Tech; major construction is under way. Vaughan's Yonge Steeles Corridor Secondary Plan guides redevelopment along the Vaughan side of Yonge Street and Steeles Avenue. Markham is studying the east side of Yonge Street around the Steeles, Clark and Royal Orchard stations for a future plan.

Neighbourhood highlights

  • The historic village. Thornhill's business district grew along Yonge Street between Centre Street and John Street in the 1830s and 1840s, and several churches from that time still stand. Both sides of the old village are Heritage Conservation Districts, one in Vaughan and one in Markham.
  • Colborne Street. A short street east of Yonge Street, which Markham's heritage plan describes as the one that best captures Thornhill's village character. The Thornhill Village Library is at 10 Colborne Street, in a heritage building from 1851.
  • Heintzman House. A historic house at 135 Bay Thorn Drive, on the Markham side, expanded in 1817 and later owned by Charles T. Heintzman. The City of Markham owns it and uses it as a community hall and event venue.
  • Clark Avenue West. On the Vaughan side, with the Garnet A. Williams Community Centre at 501 Clark Avenue West and the Bathurst Clark Resource Library at 900 Clark Avenue West.

Types of housing

Homes in Thornhill include detached and semi-detached houses, townhouses (freehold and condominium) and condominium apartments. Most apartment and condominium buildings are along Yonge Street and other main roads.

Properties inside the two heritage districts need a heritage permit for additions, alterations or demolition, so ask before you buy if you plan to renovate.

Four school boards serve Thornhill on both the Vaughan and the Markham side: the York Region District School Board and the York Catholic District School Board (English), and Conseil scolaire Viamonde and Conseil scolaire catholique MonAvenir (French).
