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 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.
