Queensville is a village within the Town of East Gwillimbury, Ontario, Canada. Currently 750 people live within the Community of Queensville. It is anticipated that Queensville will ultimately grow to a population of 30,000 people. The Queensville Centre covers approximately 50 hectares and could accommodate over 46,000 square metres of commercial development, consisting of a wide range of retail activities. These commercial uses include: retail stores, department stores and supermarkets; hotels; restaurants; business and professional offices, including medical offices; business and personal service uses; medical clinics, religious, recreational, educational and cultural facilities; and police and fire services. Over 200 hectares of Employment Area has been identified along the Highway 404 extension which is anticipated to generate approximately 12,000 jobs. Lands have also been designated for a post-secondary institution within Queensville, on the north side of the Queensville Sideroad, east of Leslie Street.
Among the private homes, the village proper contains the Queensville Cemetery, a post office, a United Church of Canada, and a complex containing a fire hall, a community centre, a public park with softball diamond, tennis courts and playground. Guy Paul Morin and Christine Jessop were neighbours in Queensville in 1984, and John Candy once owned a home approximately 1 km south of Queensville.
At one time, there were plans to build Ontario's first private university in Queensville. The site for the proposed university would have been east of Leslie on the north side of Queensville side road. It was expected that the university would occupy 65 acres (0.102 sq mi; 0.26 km2) and employ 1,000 people.
