I'll be very brief.
It's a complex issue. I don't think it's properly understood. I'm not sure that CBSA and the government are doing a great service in treating the issue as they are.
The question is not just how many people come across the border with a variant that might be an issue. It's not a statistical question. It's a question of understanding how people crossing a border through various transportation nodes might be spreaders. We don't have the answer to that and I think we have to proceed very cautiously. We don't have the answer because we're not doing enough contact tracing and we're not doing enough testing.
I think the prudential thing is to say this is a bigger problem than the statistics suggest. We have to act prudentially in that regard.
