This Sunday, June 20, the TTC is renumbering two of its bus routes so it can use the current numbers to identify two future rapid transit lines in Toronto.

That day, the transit agency designates the current 5 Avenue Rd route as 13 Avenue Rd. It also renumbers the 6 Bay route as 19 Bay.

Metrolinx is currently managing the construction of the Eglinton Crosstown light rail transit line. It expects to open the line in 2022 and the TTC will operate it as Line 5 Eglinton.

Metrolinx is also managing construction of the Finch West light rail transit line. That line will likely open in 2023 and the TTC will operate it as Line 6 Finch West.

Renumbering does not affects routing, schedules or service levels along the 13 Avenue Rd and 19 Bay routes.
