When a portion of farmland north of Bloor Street went up for sale in 1887 by the Toronto Land and Investment Corporation, it was in a unique triangular shape and since it was close enough to the West Toronto Junction, people referred to it as the Junction Triangle years later especially when people living in the area wanted to identify with their neighbourhood but it was never an official name or village, or had any official boundaries.

Later, the area became predominantly Portuguese with mass immigration from the Azores and the exodus of better-off Italian families to the northern suburbs such as Vaughan.

The fumes from the plants were clearly detectable, and studies found elevated levels of a number of organic chemicals in the area's air.

[3] In response, the city and other levels of government began fining firms that violated environmental regulations, and zoning restrictions were put in place to prevent factories from expanding.

The character of the neighbourhood has also started to change, as increasingly young downtown professionals taking full advantage of the area's multitude of public-transit and other social amenities (cycling paths) are replacing the retired factory workers of previous years.

It's been considered 'Junction Triangle the next Liberty Village' but concluded it's much more family friendly with a large portion of family homes to balance the future brownfield developments that are rapidly coming, the area residents are very actively involved with the planning processes to ensure the charm of area remains with the influx of development.

There is a clubhouse with a community kitchen, pay-what-you-can snack bar run by city staff, a skating lending program.

[5] The West Toronto Railpath presently runs through the Junction Triangle and GO Transit is about to start the construction of a MobilityHub at Bloor St and the western border of neighbourhood.

Toronto Life magazine has named this extended area one BuyNow neighbourhood due to its price affordability and proximity to downtown & transit.
