Emergency Notification System

Alert WesternU, Western’s emergency mass notification system, is powered by OnSolve MIR3.

All current members of the university community are automatically subscribed to the system for university-issued mass email notifications using their official @uwo.ca email address. You can expect to be notified by email in the event of an imminent danger, building evacuation, severe weather emergencies (such as a tornado), or critical university status updates.

Customize your settings

Members of the campus community are encouraged to log into the customization portal to broaden the ways they wish to receive notifications. The settings entered (i.e., personal mobile number or email address for you and/or family members) will be effective immediately.

Download the MIR3 app

Note: Downloading the app to your smart phone or electronic device will allow you to receive instant push notifications straight to that device. We recommend allowing push notifications so that alerts pop up on your device.

Step 1: Visit your App store.

 App Store click the link         Google Play click the link

Step 2: Confirm you have chosen the OnSolve MIR3 Mobile App.


Step 3: Download the app and set-up your account information. You will be required to enter your @uwo.ca email address to receive a verification code (DO NOT use the mobile number option). The verification code will be sent to you via email. Enter that code into the app when requested.

Important: You cannot receive Alert WesternU notifications on your mobile device unless you have a smart phone and a data plan or are connected to a wireless network. For security purposes, if you log out of the application, you will have to request a new activation code to log back into the device.
