Mount Dennis is named after John Dennis, a Loyalist shipbuilder from Philadelphia who settled on a farm here in the early 1800's. The Dennis family operated a saw mill and a woollen factory on their property, which took in all of the present day Mount Dennis neighbourhood.
During the late 1800's, Mount Dennis was known for its brick yards, the Conn Smythe Sand and Gravel pit, and a handful of market gardens that operated on the fertile plain of what is now Eglinton Flats.
In 1893 Mount Dennis built its first school which was then followed by a post office and some general stores along Weston Road. In 1916 the Kodak Company moved into Mount Dennis and became the areas largest employer.
By the 1920's, Mount Dennis had grown to the point where a plebiscite was held regarding its incorporation as a Town. The "No" vote won and Mount Dennis remained part of what was then York Township.
During the 1950's the large open fields and bush in this area gave way to new subdivisions as Mount Dennis grew from a rural outpost to an urban neighbourhood.
Mount Dennis is poised for growth with the soon to be opened Eglinton Crosstown Line which is sure to help revitalize this historic neighbourhood. The recently opened York Recreation Centre is a fully accessible 67,000-sq.-ft facility. Located beside the west bank of the Black Creek, this community recreation centre features a green roof and other green standard sustainable features.
The centre was designed with extensive input from the community. It features numerous amenities including a swimming pool, gymnasium, fitness area and community meeting rooms. York Recreation Centre is located at 115 Black Creek Drive, on the southeast corner of Eglinton Ave. West and Black Creek Drive.
The defining feature of the Mount Dennis neighbourhood is its topography, which features a series of rolling hills that climb their way northward from Rogers Road to Briar Hill Avenue. Many of these hills are bisected by curvilinear one way streets that add an old world charm to the neighbourhood. Mount Dennis is one of Toronto's most culturally diverse neighbourhoods.
