East Gwillimbury, incorporated as a town in 1971, sits at the northern edge of York Region — its northern border less than a kilometre from Lake Simcoe. Its historic communities, including Sharon, Holland Landing, Queensville and Mount Albert, predate the modern township by well over a century, having grown up around mills and river crossings.

The fastest-growing municipality in Canada

As of the 2021 census, East Gwillimbury was Canada's fastest-growing municipality of over 5,000 people, with a population increase of 44.4% between 2016 and 2021, reaching 34,637 residents. A 2025 Housing Needs Assessment estimated the town's population at about 41,000, projecting growth to 128,600 by 2051 — a scale of change that would remake the town's historic hamlets entirely.
