Thank you for your post and welcome to the Forums!
Sorry for the late reply. If I understand correctly, you are inquiring on the way ROAM LIKE HOME usage is indicated on your invoice.
Normally, the text messages usage will appear as to/from Canada to reflect how many messages were sent/received throughout your billing cycle.
ROAM LIKE HOME includes unlimited incoming/outgoing text messages to Canadian numbers and to local numbers in the country you're visiting. If you were outside of the country, and sending text messages to Canadian numbers, you should therefore have been covered.
