Things to know 

If you add a lot of street sides to your favourites, keep in mind that you will receive notifications for all of the streets you have favourited. 

If you’re not getting notifications, here are some things to check:

We do everything we can to meet the turnaround times we announce for snow removal. However, changes may occur in the event of an emergency or unforeseen conditions. 

Signage takes precedence over instructions displayed in the app. 

If you notice a discrepancy between signage and information displayed in the app, let us know.

Before the snow is loaded, our teams clear snow from the roadway and compact cleared snow on each side. 

Snow loading is when the compacted snow is removed. Snow loading is planned according to the weather forecast and snow accumulations. In fact, snow loading is not always necessary. 

The app only shows the loading stage, not the clearing stage.

You can get notifications or alerts by e-mail or text by subscribing to notifications. 

To enable or change your notifications: 

  • Create an account
  • Access your notification preferences to select alert types and topics that interest you.
