About Unionville

Unionville's roots go back to William Berczy's settlement of German families in Markham Township in 1794. The village grew around a flour mill built in the 1830s, a post office opened in 1851, and the railway arrived in 1871, with the old Unionville station still standing on Station Lane.

Main Street Unionville keeps much of its 19th-century character. It is one of Markham's heritage conservation districts under the Ontario Heritage Act, which guides how buildings in the district change rather than freezing them. Today it is a walkable stretch of shops, restaurants and heritage buildings between Toogood Pond and the Rouge River.

Homes in Unionville

Close to Main Street you will find heritage houses and some newer homes built to fit the district. Most of the surrounding streets are established family neighbourhoods of detached and semi-detached homes and townhouses on mature, tree-lined streets.
