East Gwillimbury is a town (lower-tier municipality) on the East Holland River in the upper-tier municipality the Regional Municipality of York. It is part of the Greater Toronto Area of southern Ontario, in Canada. It was formed by the amalgamation of the Township of East Gwillimbury with all the previously incorporated villages and hamlets within the township. The main centres in East Gwillimbury are the villages of Holland Landing, Queensville, Sharon, and Mount Albert. The Civic Centre (municipal offices) are located along Leslie Street in Sharon. The northernmost interchange of Highway 404 is at the North edge of East Gwillimbury, just south of Ravenshoe Road. The hamlets of Holt and Brown Hill are also within town limits.
East Gwillimbury takes its name from the family of Elizabeth Simcoe, née Gwillim, wife of Sir John Graves Simcoe, the first Lieutenant Governor of Ontario. In 1849 the Baldwin Act incorporated the Township of East Gwillimbury effective January 1, 1850. The Province of Ontario incorporated the Town of East Gwillimbury effective January 1, 1971.
As the East Gwillimbury area grew, a number of communities developed. They were the villages or hamlets of Brown Hill, Franklin, Holland Landing, Holt (formerly Eastville), Mount Albert, Queensville (formerly colloquially known as The Four Corners), Ravenshoe, River Drive, and Sharon (formerly Hope).

Police services are provided by the York Regional Police.
Planning
In March, 2006 the town council passed a policy during the Committee of the Whole Council Meeting which requires all residential developments of at least ten units to comply with Energy Star qualifications. The town's mayor described potential benefits of the program: "Energy efficient housing is the best way to ensure that East Gwillimbury's residents are insulated against rising energy costs and won't have to make costly energy efficiency upgrade retrofits in the future."
East Gwillimbury is the first jurisdiction in Canada to require Energy Star certification for residential units.
The 2010 Official Plan
In June 2010, town council passed the Official Plan for the Town of East Gwillimbury. The Official Plan was praised for its consultations
with the public, developers, and other stakeholders. Designated as a future growth area under the Places to Grow Act by the Province of Ontario, East Gwillimbury will see growth from 23,000 residents in 2010, to approximately 88,400 people and 34,000 jobs by the year 2031. Despite the large amount of growth, almost 75% of East Gwillimbury land will not be developed as it is part of both the Greenbelt and the Oak Ridges Moraine. Rather than being spread out throughout the town, growth will be concentrated in the existing villages of Holland Landing, Sharon, Queensville and Mount Albert. Queensville will see the most growth, going from a population of 650 people in 2010, to over 30,000 residents. Much of the growth has been proposed since the early 1990s – however, growth in East Gwillimbury cannot occur until the York–Durham Sewage System is extended into the town, which has been postponed until 2012 or 2013, when costs are lowered. In October 2011, the Regional Municipality of York advised the Ontario Municipal Board, that they support the Official Plan for East Gwillimbury.
