The Toronto Railway Company electrified the line on April 19, 1894, and extended it north to Dupont Street on July 10, 1894.

South of the rail corridor, streetcars ran along the edge of Fort York to provide seasonal service to Exhibition Place.

[10][8] With the Line 2 Bloor–Danforth opening, service north of Bloor Street to Vaughan Loop was discontinued, with cars terminating at the then-new Bathurst station.

Also, during this time, the overhead wire was rebuilt to allow for subsequent pantograph operation along Fleet Street, the first location to be so equipped.

On February 18, 2018, streetcars returned to the route,[17] followed by another period of bus replacement that began on September 2, 2018.

[18] On June 23, 2019, streetcars returned to 511 Bathurst, ending the temporary replacement bus service.

[20] From April 20, 2020, until January 3, 2021, buses temporarily replaced streetcars on 511 Bathurst in order to accommodate several TTC and City of Toronto construction projects.
