The TTC is now providing its customers with email alerts of any disruptions in their service.
By registering with My TTC e-Alerts you can choose to receive convenient and important service alerts by email. My TTC e-Alerts are real-time email notices that keep you informed of all major subway and RT service disruptions.
In the near future, you will be able to customize My TTC e-Alerts to your usual surface, subway or RT route, and days/times that you typically travel. That way, you only receive notices of delays that affect you.
