on the URL you provided ( http //www.ctv.ca/activate ), the page appears to be currently ("Oops! Something went wrong!") and is not loading the expected activation interface.

If you need further help with a specific device (e.g., Fire TV, Roku), let me know and I can provide device-specific steps.

Once the technical issue is resolved, the ctv.ca/activate page will allow you to sign in with a Bell Media account or TV provider credentials and enter the activation code shown on your device.
