Was it removed from your account a couple years ago? Or is it still 'active' on your account but doesn't work?
If it is still on your account; Try this https://activations.shaw.ca/activate.aspx
Otherwise you will have to get in touch with a Shaw agent and get it added back to your account.
If step provided by kevinds doesn't resolve your issue please send me a DM and we'll help you get everything going again.
