If I understand the question correctly, from my point of view, the biggest concern I have is the safety of the individuals coming into Canada. The safest way to come into Canada is at an official point of entry.
If you're crossing between points of entry, regardless of the circumstances, regardless of the conditions, you're taking on additional personal risk that may not be warranted.
I think, regardless of whether the STCA is in place or not, we encourage people to come across at points of entry primarily, first and foremost, for their own personal safety.
