I think that because the vaccine mandate only applies to outbound travel and you're not using ArriveCAN for outbound travel, in that sense it's been slightly decoupled, based on the announcement that was made this week. The caveat I would give, though, is that because unvaccinated individuals are now going to be able to travel, they have to come back into Canada. I think that's where you're going to see additional bottlenecks created. They have to go through the ArriveCAN verification.
