Perhaps I could add something by way of example.
Talking to exporters through the port, in particular for meat products, and using the Korean free trade agreement as an example, I've heard directly from them that the fact that the U.S. signed an agreement before Canada meant that they lost market share in Korea, which they've struggled to recover since. They were very pleased to see the Canada-Korea Free Trade Agreement in place, but they would rather have seen it in place before the U.S., because of that loss of market share. It's a small example of the very real risks to Canadian exporters of being disadvantaged by differential trade agreements.
