Towns and Hamlets
The town of Whitchurch–Stouffville consists of several distinct communities and the intermediary countryside. The largest urban area is Stouffville proper, while other communities in the larger town include Ballantrae, Bethesda, Bloomington, Cedar Valley, Gormley, Lemonville, Lincolnville, Musselman Lake, Pine Orchard, Pleasantville, Preston Lake, Ringwood, Vandorf, Vivian, and Wesley Corners. The town is bounded by Davis Drive (York Regional Road 31) in the north, York-Durham Line (York Regional Road 30) in the east, and Highway 404 in the west. The southern boundary conforms with a position approximately 200 metres north of 19th Avenue (York Regional Road 29), and is irregular due to the annexation of lands formerly part of Markham Township in 1971.
