I just want to endorse what Mathew said. The borders are critically important, not just the streamlined procedures, but also the infrastructure. As an example, last Thursday night, May 4, I travelled from Windsor to Sarnia. The quickest way is through the United States, and the Blue Water Bridge was lined up with trucks at midnight, right over the bridge. There was no other traffic on the bridge. You need the resources at the bridge as well.
We need to keep in mind that a vehicle built in North America can cross the border seven times. Every single time it goes through the border, it's hitting those traffic jams and requiring those manifests. It puts us at a competitive disadvantage to vehicles that are built outside of the region and shipped in, which only cross the border once. We're facing seven times that inefficiency.
