Settlement began here after the opening of Yonge Street in the mid-1790s and by 1802 a grist mill and sawmill were operating on the Don River. The community developed slowly until 1829 when Benjamin Thorne built a large flour mill, tannery and store. Within a year, the village also contained a post office named “Thornhill,” a church, school and tavern. Thornhill's growth as a milling and agricultural centre suffered after 1846 when the loss of British markets drove Thorne out of business. Further decline occurred when the Northern Railway bypassed the community in 1853. Recovery began with the flow of grain southward during the American Civil War and by 1867, about 700 residents were recorded. From 1931 to 1971, Thornhill was an incorporated Police Village.

Vaughan side) and Nicholas Miller (who settled on the Markham side). Of particular importance was the arrival of Benjamin Thorne in 1820 from Dorset, England. The settlement came to be known as Thorne's Mills, and later, Thorne's Hill, from which its current name is derived. (Thorne committed suicide in 1848, after a serious wheat market crash.)

In 1931, Thornhill became a "Police Village"; before that time, Thornhill had no independent status and was split between the townships of Vaughan and Markham along Yonge Street. The creation of the Police Village gave Thornhill its own political boundaries. The village was headed by a reeve.
