Mount Dennis is a hilly community with the Humber River on one site and the Black Creek on the other. The neighbourhood is culturally diverse (with over 30 ethnic groups). Named for John, Dennis, Philadelphia Loyalist who settled there and built a sawmill and a woolen factory, and by the late 1800s the area was best known for gravel pits and brickyards. Just to the south, in the fertile Eglinton Flats area, market gardens thrived. By 1916, the area added a Kodak factory, and by the 1950s the area's residential areas filled up.
Motorists are 10 minutes from Highway 401 and Highway 400 (via Jane St), while downtown commuters can take Jane St south to Lake Shore Boulevard. TTC buses along Jane Street and Weston Road connect to the Bloor-Danforth subway, and the Trethewey Drive and Eglinton Avenue buses connect to the Eglinton West station on the Yonge-University-Spadina subway.
The community is served by 4 elementary schools, 2 Catholic elementary schools, 3 public high schools, and 1 public library. York University is a few miles to the North via Jane & Steeles, and Humber College's North Campus is accessible view Weston Rd & Finch. University of Toronto is accessible via either subway route.
Mount Dennis has a thriving shopping district along Weston on both sides of Eglinton, with a diverse range of stores and restaurants, with special events and festivals thrown in. There are some shopping plazas along Jane St, with some malls north of the 401.
The community is wrapped around the sports fields at Eglinton Flat, which have facilities for pretty well every sport, along with change rooms and picnic areas. The neighbourhood is adjacent to the Humber River paved recreational pathways, which continue south to Toronto's lakefront. Westlake Memorial Park has a popular toboggan hill, ball diamonds and playground. The executive length Scarlett Woods Golf Course is in the SW area of Eglinton Flats.
Home buyers can find houses built from recent times all the way back to the late 1800s. The older homes are gradually being replaced by modern infill-style homes. Many Mount Dennis homes have views of the Humber Valley or back onto area parks. Homes in this community are in the low to affordable range, with newer homes in the mid-price range.
