Leslieville is a low strip of two- and three-storey storefronts along Queen Street East, brick below and apartments above, backed by streets of small houses. The street follows the old Kingston Road and took its current name in the 1880s, after the area north of it was annexed to the City of Toronto.
The neighbourhood's name comes from George Leslie, a Scottish immigrant who ran the Toronto Nurseries here from the 1850s. , a few blocks north, still has a plaque about him. His son became postmaster of the local post office in 1862, and the Leslie Post Office gave its name to the surrounding streets. Alexander Muir, the first principal of Leslieville Public School, was said to have been inspired to write "The Maple Leaf Forever" by a leaf falling from a tree near his home. The tree came down in 2013. Its trunk still stands beside , Muir's house, in the park now named for the song.
Several buildings from the street's early growth survive on Queen Street East. The , at Leslie Street, was built in 1870 as the Morin House Hotel and keeps its High Victorian brickwork under later paint and signage. , an Edwardian building from about 1910, has been run by the same family since. The red brick dates to 1878.
One block over, Carlaw Avenue was a manufacturing street through both World Wars. The Wrigley chewing gum plant there is now , one of several factories since adapted to other uses. Queen Street East itself was still lined with auto shops and gas stations as recently as 2000. Gio Rana's opened there in 2002, when the street had almost no restaurants. Jim's, the longtime breakfast spot, closed in 2016.
