Eglinton Flats is Toronto's largest regional sports field facility. Built on Humber River floodplain, the complex occupies three quadrants at the Jane Street and Eglinton Avenue West intersection. Scarlett Woods Golf Course, also operated by Toronto Parks & Recreation, occupies the fourth quadrant at the south-west corner. In 1972, the former Metropolitan Toronto Council adopted a development program for South Humber Regional Park including Eglinton Flats. The facility opened in 1977. Six of the twelve pay-as-you-play tennis courts became available for year-round use after an inflatable fabric bubble was installed in 1989.

The complex takes its name from the area's characteristic landscape and Eglinton Avenue West. Interestingly, this road has an association with sports and contests since it was named after Archibald, the 13th Earl of Eglinton, who held a mock medieval tournament at his castle in France during August 1839. The land at Eglinton Flats was owned by the Scarlett family during the mid-1800's and later used extensively for market gardens until Hurricane Hazel devastated the area in 1954. The Metropolitan Toronto and Region Conservation Authority acquired the land from the then Borough of York and many private owners before transferring it to the Park & Culture Department for maintenance and operation.
