The Harbord streetcar line was an east-west line within the Toronto streetcar system. The route was named after Harbord Street even though only a small portion of the route was along the namesake street. One distinct characteristic of the route was its zip-zag nature, making many 90-degree turns onto the various streets along its route. The route was retired in 1966 when the Toronto Transit Commission (TTC) opened the Bloor–Danforth subway line (today Line 2 Bloor–Danforth), the city's first east-west subway line.[1][2][3]
