Hoping someone can answer this, not sure if its a YYC specific question or a CTA question.

I'll have a 9 hour layover in YYC due to a few one-way flights booked on separate itineraries, but it will require me to exit the secured area, grab my luggage, then re-check back in with the second itinerary. I have a friend in YYC that wants to meet up, but can only meet up in the evening (a few hours before my flight), but I also want to use the MLL as part of my J ticket during the layover.

Will there be any problems if I check-in and go through security with the new boarding pass, access the MLL, then leave the secured area back to departures area to meet my friend for an hour, before going through the same security again to make my way towards the gate? Not sure what the rules are about a boarding pass that already passed through security once, and is passing through again.
