Hello BearWoman,
Welcome to the community!
Fido and Rogers often have their own plans, features and promotions. As far as I am aware, Fido does offer some plans with Canada/US calling. However, it was only available to customers in Québec. In fact, it is still on the Québec plan offerings (available for new activations only). Apparently, the offer might have been extended to customers with an Ottawa area code (see here). According to that article, you would require a hardware upgrade since you already have Fido services. If that is the case, it would not be on the Ontario plan offerings as it does not extend to all of the Province.
If you don't live in Québec or the Ottawa region, you unfortunately won't be able to avail of those plans. If you do require Unlimited US calling, Fido does offer an add-on (see here). Though, it should be noted that the add-on does not include US roaming.
While there may be some moderators still willing to assist via PM, you should note this forum is community-driven and no longer intended as a venue for customer services. If you would like to discuss your options, you would need to contact customer service. In addition, 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
