Again, perhaps I'll turn to Justine, but I'll just say that one of the reasons the supply chain has worked so effectively throughout COVID is because we were able to keep fluidity in products moving across the Canada-U.S. border. If that were jeopardized for a significant period of time, it would risk causing a whole variety of disruptions, particularly when you're talking about the transport of live animals. We're in winter, and the animal welfare risks associated with that are significant. It's also a time of year when we're heavily dependent on imports of fresh fruits and vegetables, particularly from the United States and Mexico.
Certainly, as I said, if there were enduring disruptions in cross-border travel, it would pose some risks to the supply chain, but perhaps Justine will add to that.
