"Your local calling area depends on where your phone is physically located, regardless of the phone number"
"For example:
If your outgoing call is picked up by a Calgary cell site, then your local calling area is the Calgary local calling area, even if you have an Ottawa-based phone number."
"Receiving calls while you're located outside of your home city is considered long distance, regardless of where the call originated."
"For example:
Someone located in Vancouver with a Toronto cellular number is charged long distance because he is outside the Toronto local calling area."
