A colleague is heading to Pearson later today, and with time being tight wanted to be able to have a meeting with her at the airport given that it's an International flight and she'll be there with a few hours to kill.

I've looked everywhere online for Gate Passes for Non-Travelers at Toronto Pearson, but nothing after 2021 really and the only link on the Pearson website is a portal for employees. Nothing on airline websites either, such as Air Canada.

...Is this still possible? Any insight on how to go about doing it?

We can risk going to baggage drop-off / check-in together and hope the agent can offer one, but really feels like a random uncertain gamble at this point. She is flying Business class if it helps, going overseas.
