The border was closed to non-essential commerce but remained open to essential commerce. It works extremely well if you're in a tractor-trailer or a train car. Critical supplies are going back and forth, and I think both governments have done a very good job on that. There have been some other instances, though, where it wasn't clear. Border agents have a lot of discretion to determine what is essential commerce and what isn't. There have been some instances where someone was turned away, but actually they should have been allowed to go forward.
Our idea for that is an “essential commerce” designation. We actually have a pilot project idea for this. Just like you have a “trusted traveller” designation, you could have an “essential commerce” designation. It could also be used for resumption of commerce after this, when you would add a health element to the screening.
The border is going pretty well, but it's not perfect and we think we have a solution to propose.
