The weather forecast for the City of Toronto and surrounding area is calling for freezing rain with the possibility of an accumulation of ice.

TTC staff have put a plan together to ensure the TTC is prepared if there is a severe weather event.


We have been applying anti-freeze to the overhead network to keep ice free from the wires so streetcars can collect energy and operate. To prevent significant ice build-up, we have also applied “sliders” to trolley poles on every fifth streetcar that knock ice off the overhead, should it accumulate.

Overhead crews are on standby and will be positioned around the city in the event of power loss or overhead wires coming down.

The same anti-freeze used on the overheard has been applied to all switches across the network. Storm cars will run on all routes, keeping switches free of any ice build-up that the anti-freeze was unable to successfully prevent.

On the 501 Queen streetcar route, buses will operate in the east end from Kingston Rd. to Neville Park so we can keep more streetcars in the downtown core, which will help keep switches and overhead wires clear of ice. Buses will also operate on the 506 Carlton and 512 St Clair routes to keep more streetcars in the downtown core on the 501, 504 and 509 routes.

  • 501 Queen - operating in three parts:
    • Buses operating between Long Branch and Humber loops in the west
    • Streetcars operating between Humber Loop and Kingston Rd
    • Buses operating between Kingston Rd. and Neville Park Loop in the east
  • 502 Downtowner – Buses operating on the route.
  • 503 Kingston Rd. -  Buses operating between Bingham and Kingston Road Loop.
  • 504A King –  No service to Distillery Loop. A Wheel-Trans vehicle is available to shuttle customers from Distillery Loop to King St.
  • 504B King – No service to Dufferin Gate Loop. Customers can board a 29 Dufferin bus north and transfer at King St.
  • 505 Dundas – Buses operating on the route
  • 506 Carlton -  Buses operating on the route. Buses will serve High Park Station instead of High Park Loop
  • 509 Harbourfront - operating normally.
  • 510 Spadina – streetcar service terminates at Queens Quay and Spadina. Customers can transfer to the 509 route, which has increased service.
  • 511 Bathurst -  Buses operating on the route.
  • 512 St Clair -  Buses operating on the route.


Storm trains will operate overnight to keep the power rail clear of ice. Trains with an anti-freeze agent are on the line now and the agent is deployed when it begins to rain. The same process occurs on Line 3 Scarborough.

Crews will keep switches clear in yards using switch heaters, but will also manually ensure that the heaters are working effectively and take action if they are not. Workcars will act as storm trains in the yards to keep the power rails clear of ice.


The TTC relies on City Transportation to keep all roads clear of ice. We have adequate buses available in the event of a major power outage that knocks out our ability to operate streetcars. If the subway is affected by a power outage, shuttle buses will be deployed.


The Transit Control Centre will issues e-alerts, tweets and other communications as the weekend progresses. Customers will be alerted to any service changes because of power outages, route diversions or other disruptions caused by the weather. Media relations staff will keep media apprised of service changes and Customer Service (@TTChelps) will help answer customer questions and provide alternative transit options online and on the telephone.
