Well, it would very quickly stop most production in most sectors. To be very blunt, Mr. Lewis, if stuff can't move back and forth across the border, the manufacturing sector can't operate. There's almost no part of the supply chain that doesn't have linkages either going out of or coming into the U.S. That border crossing is essential. A lot of this is discussed in terms of the automotive sector, but, actually, the second-largest volume going across the border is foodstuffs. Not only would it impact manufacturing, but it would impact what you and I eat on a daily basis and what we'd be able to buy from grocery stores. The impact wouldn't just be on the manufacturing sector; it would be pretty big and pretty wide pretty quickly.
Yes, you could reroute and go through, say, the Niagara frontier or through Sarnia, as you mentioned. It's not very convenient, but it can be worked around.
Look, we've been advocating a long time for better testing and better vaccines for all essential workers, and that includes our border guards. Certainly we're coming at it from a manufacturing perspective, but that's a really key part. They're just as important as the truck drivers themselves who would moving the goods back and forth.
Yes, it's fundamentally important that that gets taken care of.
