Buttonville is a suburban neighbourhood in the city of Markham, Ontario, Canada, west of the larger Unionville neighbourhood. It is a former hamlet, named after its founder, John Button. About 30,000 residents live in the area. It is located along the Woodbine Avenue corridor from approximately Highway 7 in the south to Sixteenth Avenue in the north. The Rouge River is in the northeast and Buttonville Airport and Highway 404 are in the west, with three interchanges. The residential area is located in the eastern, northeastern and the northern section while the industrial area is situated to the west and south down to Highway 7. The area is home to many technology companies near the airport (which incidentally is the location of where weather reports are taken for the Weather Network). There is talk about renaming the community, the John Button Community after its founder since there has been lots of confusion between Unionville and Buttonville, which is popularly considered to be part of Unionville.
The area was first settled by William Berczy who got an original crown grant of land. The village in Unionville was named after John Button (b. 1772) who bought property here in 1808. By 1860, John Button's descendants owned a number of lots in what is today Buttonville. By 1878 the village had a post office, a grist mill, a wagon maker, a school, a Lutheran church and a Methodist church.
Unionville housing developments did not began until the 1960s near Cachet Woods at Woodbine Ave. and Major Mackenzie Drive, and the industrial area began to appear further south. In the 1980s housing developments came to the western part of Markham along with the industries which later flowed with technological and financial companies including Allstate. Buttonville was first accessed when Highway 404 opened several interchanges in the 1970s. Between 1994 and 1996, more houses continued northeast of Buttonville and a few years later, north of the airport and more housing continued until 2004.
