Neighbourhoods & character
- Main Street Unionville is a preserved heritage village whose period buildings are virtually unchanged from the area’s founding in 1794; it developed its “Victorian Village” atmosphere after preservation efforts in the early 1980s and hosts the Unionville Festival and summer jazz and Celtic festivals. [3]
- Cornell, in east Markham, is a master-planned New Urbanist community designed by Duany Plater-Zyberk (DPZ) after a 1992 international competition — rear-laneway garages, a connected grid of short tree-lined blocks and walkable five-minute neighbourhoods. [4]
Parks & green space
- Rouge National Urban Park extends from Toronto north into Markham (and Pickering, Uxbridge and Whitchurch-Stouffville), spanning about 79.1 km² — the largest urban protected area in North America. [6]
