On the evening of Thursday, October 1, 2026, IT Services will renew the security certificate that secures authentication to McGill's wpa.mcgill.ca, wpa.bus.mcgill.ca, eduroam, and cusm-muhc.mcgill.ca Wi-Fi networks.
This certificate allows you to sign on to the Wi-Fi network securely.
For Android and some Windows devices, the change will be seamless, and no action is required. However, all iOS/MacOS devices and most Windows devices will display a message prompting users to accept the new certificate.
