If you regularly call the US, Fido does offer an Unlimited US calling add-on. Alternatively, they do also offer the Preferred International rate add-on. You can view the add-ons in the link above under Long Distance. You can also view the Preferred rates to other destinations from the link above.
Hope this helps 😀
