You have to call in to get it. Best way is to dial in with your phone and use option 4, 1, 4 to reach the retentions department.
Be aware that the plans that list US & International text messages to NOT include Canadian text messages, so you probably don’t want those.
However, they have a few other options that aren’t listed there, which include unlimited Canadian text messages, but no US & International text messages, and this is probably what you would want.
I added it last night, and this is what I get for my iPhone:
$10.40 for unlimited Canadian text (including picture/MMS), call display with name display, visual voicemail, and ringbacks.
You should get the first month free as well.
