So my group of 4 (wife, 2 kids, me) are flying back from France in a few weeks. We are dropping off the kids in YUL, as the grandparents are picking them up from there. My wife plans on clearing customs at YUL while I continue to YTZ with the luggage. She hands off the kids and goes back through security for a later flight to YTZ. At least that's the plan.

Are there any problems with this strategy? She's on one ticket (NCE-ZRH-YUL-YTZ). It's an Aeroplan award flight, if that matters.

Thanks.
