The Summerhill neighbourhood in central Toronto was named after 'Summer Hill' house, built in 1842 by Canadian transportation baron Charles Thompson.

Much of the area was once part of the Thompson estate but was subdivided by his heirs in the 1880s.

In the 1880s, the North Toronto Railway Station was established on Yonge Street and the neighborhood of Summerhill quickly developed around it.

The Railway station was rebuilt in honour of a visit by the Prince of Wales (later Edward VIII) in 1916.

The neighbourhood underwent very little growth after the railway station closed in 1931 but was again revitalized by the launch of the Summerhill Subway station in 1965 (a part of the Toronto Transit Commission [TTC]).

The old railway station is still there and currently serves as an LCBO outlet. The station, along with the still-operational CN railway bridge, is a landmark of the neighbourhood.
