Whitchurch-Stouffville is located about 50 kilometres north of downtown Toronto, and 55 kilometres northeast of Toronto Pearson International Airport. Its motto since 1993 is "country close to the city". The Township of Whitchurch was incorporated in 1792 and the Village of Stouffville was established in 1877. The two merged in 1971 to form the modern-day version of the town.
Between 2011 and 2016, the town grew 21.8 percent, making it the second fastest growing municipality in York Region. The Oak Ridges Moraine Conservation Act, the Greenbelt Protection Act, and the Places to Grow Act govern future growth as a way to prevent urban sprawl on environmentally sensitive land and to accommodate future growth in approved settlement areas.
