Hello Maunareddy,
Welcome to the community!
Unfortunately, there is no way to cancel services online. You should also note this forum is community-driven and not intended as a venue for customer services. We would not have access to customer accounts. If you wish to cancel your services, you would need to contact customer service. If you have already left Canada. They do offer a contact number you can call from abroad. They can also be contacted via Live Chat, Facebook, or Twitter. Those methods can be accessed via the contact page posted above.
Hope this helps 😀
Cheers
