Maybe I'll take a crack, and then Steve might want to come in.
As Steve mentioned earlier, since the border measures were put in place, they included provisions to allow essential workers and essential goods to continue. This includes moving goods back and forth across the border. At the same time, I think your point is very well taken. There obviously are some companies that have been affected and haven't been able to have visitors or technicians come in. I know that's something we have looked at.
I do know that in some instances, where it's getting to the point of national interest and there has been a need for technicians to come in, there are some provisions available to allow that to happen. I'll give you one example in that regard. It perhaps doesn't exactly fit yours, but it might serve to illustrate it. Canada, of course, is an aerospace leader. Whether in the production of airplanes or whether in simulators, Canada is the only place where some of this can be acquired. The folks who need these services or who are acquiring these products had to come into Canada, and there were exceptions made away from the 14-day quarantine. I can't speak to exactly the examples you raised, but there have been instances to allow that to happen.
The last comment I'll make is that the arrangement with the United States, as everyone knows, has been reviewed on a monthly basis and has been extended every month. Now the additional provision about people entering Canada having to go through testing is in place until April 30. These are measures that are reviewed on a regular basis. I think everyone wants to see them eliminated as soon as possible, but it will be very much guided by the science and by those experts who will be able to tell us when the time is right to begin to relax them.
Your point is very well noted in terms of the critical industries and the need to get access to specific people in order to keep sales moving.
