The inclusion of "Do_Not_Use" does suggest it's an internal message (to the PM operators) to select a different item (which probably has the same name). Probably not meant to be seen by the customer, lol, congrats on reporting the first "bug" on PM's website refresh, haha.
Comparing PM's current version of the page with two older cached versions of the page shows only two details in the entire Terms of Service have been substantially changed (ignoring minor changes to wording, but bold italic text is entirely new):
"Province-Wide option includes outgoing calls you make anywhere in Canada to a number with an area code in the same province, and incoming calls you receive while you are in your home province. A Long Distance Talk Add-On is required to receive incoming calls while you are outside your home province."
"Add-Ons are available for use only with an active plan. Long distance Add-Ons require a monthly talk feature on the rate plan."
Not sure if this means PM actually changed the add-on itself, though, they could have just clarified terms a little better when they revamped the site.
