Nothing, it is a standard process. Just remember to say 'NO'to any additional service, and tell them clearly that you don't need long distance access if you don't want it from Bell.
They may still 'ignore' or/and 'forget' your requirement and give you the service, so you need to check you line to make sure it is not there by dialling 1700-555-4141.
And bell is always not puncture at all, you are lucky if they show up half a day later, they may show up half a day in advance and say you are not in, or they will tell you they can not make it when you call them a day later.
