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.
