At the outset of the 20th century, St. Clair Avenue was a narrow stretch of road, bordered by stretches of farmland and broken by a series of ravines to the east of Yonge Street.

Thanks to various annexation efforts, the majority of the street fell within the city of the Toronto by 1911, at which point the construction of streetcar track ushered in a development boom that would rapidly change the character of the street.

Archival photos show just how closely linked St. Clair's history is linked the streetcars.
