Buttonville is a community named after the founder of the former farmlands, John Button, within the city of Markham in the west part of Unionville. About 30,000 residents live in the area. Rouge River is to the northeast and Buttonville Airport is directly west of the community Highway 404 is to the west with four interchanges and the nearest interchange with the Highway 407 Express Toll Route (ETR) is 2 km south on Woodbine Avenue. The population live in the eastern, northeastern and the northern parts while the industrial area of Markham is to the west and the south down to Steeles. The industrial 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 and getting rid of its nickname Buttonville, since there has been lots of confusion between Unionville and the nickname Buttonville, which is also located in 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.
