As part of a major expansion of night transit service across Metropolitan Toronto, the TTC extends the 10 BLOOR-DANFORTH route and redesignates it 300 BLOOR-DANFORTH BLUE NIGHT as part of its new night service branding, including blue rollsigns. Service extended west of Jane, replacing part of the 49A BLOOR WEST night service and east of Main, replacing part of the 93 DANFORTH EAST night service. Buses operate from Mill Road (looping via west on Bloor, north and east on Markland and south on Mill Road) via Bloor Street, Kipling Avenue, Dundas Street, Bloor Street and Danforth Avenue to Danforth Road (looping via Danforth Road, Warden and Danforth Avenue back to route). Buses operate out of Danforth, Lansdowne and Queensway Garages.

Additional service is provided eastbound from Jane, Sunday mornings (for people out late on Saturday night) from 1:50 a.m. to 3:05 p.m., providing a combined service frequency of every 7-8 minutes. This is listed on maps as a 300A branch. A number of trips at the end of the day terminate their runs at Main, Coxwell, Pape, Lansdowne and Kipling, but these aren’t designated as formal branches of the service.

April 1991

Service cut back at the west end to loop via Bloor, West Mall, Burnhamthorpe and East Mall back to Bloor. Service no longer provided on Bloor west of West Mall, Markland or Mill Street.

February 16, 2003

Service extended beyond the west end to provide night service to Pearson Airport, sharing service with the 307 EGLINTON WEST NIGHT. Every second bus on this route operates via west on Bloor Street, north on The West Mall, east on Burnhamthorpe Road, north on Highway 427, west on airport internal roads to Terminal 3, then east on airport internal roads to Terminal 2. Returning, buses travel from Terminal 2, south on Highway 427, exit at Burnhamthorpe Road, east on Burnhamthorpe Road, south on The East Mall, east Bloor Street back to the route.

The TTC lists approximate departure times as follows:

From Kipling Avenue and Dundas Street (every day of the week, except *Sunday only):

300A Bloor-Danforth: 2:36 a.m., 3:02 a.m., 3:32 a.m., 4:02 a.m., 4:32 a.m., 5:02 a.m., *5:32 a.m., *6:04 a.m., *6:34 a.m.; *7:04 a.m., *7:34 a.m., *8:04 a.m.

Service on the 300A Pearson Airport branch extended to serve the new Terminal 1. Buses operate over the present route north on Highway 427, to Terminal 3 Departures, then to Terminal 2 Arrivals, then to Terminal 1 Ground, then southbound on Highway 427 back to the existing route.

January 30, 2007

Service adjusted at Pearson Airport thanks to the closure of Terminal 2. Buses now serve Terminal 1 and Terminal 3, in that order.

February 17, 2008

Service increased due to overcrowding. Buses operate on the main branch at every six to seven minutes during busy periods, every 15 minutes at other times.

May 10, 2009

Two buses entering service at Pearson Airport in the early morning are adjusted to start service at Terminal 3, so that all stops in the airport are served. Buses now depart Terminal 3 at 4:17 and 4:47 a.m., departing Terminal 1 at the regularly scheduled times of 4:23 and 4:53 a.m. respectively.

February 16, 2014

Effective on this day, service is revised through Toronto Pearson International Airport so that the stops follow in the same order as 58 MALTON and 192 AIRPORT ROCKET. Night buses now stop first at Jetliner Road and Airport Road at ground level, then Jetliner Road at Airport Road on the upper level, then Terminal 1 Ground Level and then Terminal 3 Arrivals Level before leaving the airport.

June 22, 2014

As part of a system-wide reorganization of route branch designations, westbound buses operating to the West Mall are redesignated 300B. All eastbound buses to Warden are designated 300.

October 11, 2015

Service revised to extend a branch of the route to Kennedy station, replacing service on part of the old 302 DANFORTH-McCOWAN ROAD NIGHT route. Buses on the 300B “West Mall” branch are altered to operate from the West Mall and Burnhamthorpe Road via east on Burnhamthorpe, south on the East Mall, east on Bloor, south on Auckland, east on Dundas, east on Bloor, east on Danforth Avenue, northeast on Danforth Road, north on Brimley and west on Eglinton Avenue to loop through Kennedy station. Buses return via east on Eglinton, south on Brimley, southwest on Danforth Road, south on Warden, west on Danforth Avenue, west on Bloor, southwest on Dundas, north on Auckland, west on Bloor and north on The West Mall to Burnhamthorpe.

Service connects to the new 302 KINGSTON RD-McCOWAN NIGHT at the Brimley/Eglinton intersection. Service on the 300A “Pearson-Warden” branch is unchanged. Service operates every thirty minutes on both branches during weekends and holidays, and at 20 minute intervals on weekday nights. Early morning Sunday service operates at 12 minute headways on both branches, with service combined to be twice these frequencies between Warden Avenue and the West Mall.

Service continues to operate out of Birchmount, Eglinton, Mount Dennis and Queensway garages using Orion VII low floor buses.

March 28, 2021

For the first time in TTC history, all runs on this route are now provided by eight of nine conventional bus garages: Arrow Road, Birchmount, Eglinton (Comstock), Malvern, McNicoll, Mount Dennis, Queensway and Wilson Garages.

September 5, 2021

Buses on the 300 that operated from Arrow Road Garage ceased as 45 KIPLING buses were moved to Mount Dennis Garage.

Sunday, January 5, 2025

To support the deadhead to revenue service initiative, some trips on weekdays and weekends will be adjusted to go out of service at either Toronto Pearson International Airport Terminal 3, 3450 Danforth Avenue, The East Mall at Gibbs Road, or Kennedy Station instead of various short turn locations along the Bloor-Danforth corridor.

There will be no change to scheduled service levels resulting from this adjustment.

February 16, 2025

Once again, buses on the 300 are now supplied by Arrow Road Garage as all eight of nine conventional bus garages provide service to this route.
