Information About School Bus Delays 

Traffic congestion and varying road conditions can impact on the flow of traffic in Toronto, and this is particularly true during the winter months when snow and ice can be a major factor.
The Toronto Student Transportation Group is pleased to provide information about school bus delays digitally through their website at
Click on the pink bar at the top of the homepage to get a listing of any bus routes that are being impacted.
Navigate through the entire website for resources and information relating to student transportation and school bus safety.   


Reporting of cancellations or closures due to inclement weather
Cancellation of school bus transportation or school closures due to inclement weather will be reported through the following vehicles:
  • News releases to all media outlets in Toronto (Note: although the news release is provided to the media outlets, there is no guarantee that all television and radio stations will broadcast the information in a timely fashion.)
  • Communications will endeavour to send an email to everyone on exchange to advise them of any cancellations or closures
  • Schools will be asked to update their phone messages to reflect the status of school operations.
  • Communications will also endeavour to send out the information electronically to E-News subscribers (Note: If you do not already subscribe to E-News, but wish to do so, please visit our website at and click on the E-News icon on the top right hand side of the homepage)
  • Twitter will also be used to provide updates throughout the day. Follow the Board on Twitter@TCDSB.
  • Updates will also be posted on the Board’s 24-hour information line, 416-222-8282, extension 2873.
  • The information will also be posted on the Board’s website at as an alert—this will appear on the home page of the website as well as all school pages. 


Cold Weather Alerts


A Cold Weather Alert will be issued when temperatures are expected to be -15C or colder, or wind chill is expected to be -20C or below. Other environmental factors, such as heavy precipitation, are taken into consideration. The alert is meant to target vulnerable groups, particularly the homeless and their caregivers, that unfavourable conditions are expected. The alert triggers responses by Shelter Support and Housing and community partners to protect vulnerable people within the city, such as opening drop-in centres. 


A cold weather alert may not necessarily translate into the need for an indoor recess as there is a low to moderate risk of frostbite.  Staff should be encouraged to remind students to dress appropriately for the weather conditions, and principals should monitor local weather conditions and refer to the Board’s protocol for guidance.
When in doubt, check with your superintendent.
An Extreme Cold Weather Alert will be issued by the Medical Officer of Health when temperatures or wind chill are expected to reach -30C or colder for at least two hours. This corresponds with the Extreme Cold Warning issued by Environment Canada. The alert is for the entire population that extreme low temperatures are expected.
When there is an extreme cold weather alert, the risk of frostbite is greater and principals should consider indoor recesses, or shortened recesses to ensure the safety of students and staff. Schools are encouraged to monitor local weather conditions and consult with their superintendent if clarification is needed.
