Welcome to the community!
What plan do you have? Most of Fido's current plans include Canada-wide calling. With those plans, the long-distance charges within Canada are included. If your plan includes Unlimited Canada-wide calling, then there would be no additional long-distance charges for calls made within Canada an to Canadian phone numbers. However, some older plans may only include local or Provincial calling. You should be able to view your type of included minutes via My Account.
Hope this helps 😀
