That's a very good question. It's very hard to come up with a precise number because it's a very complex question. We know the effects would be catastrophic in an environment where our companies have organized their supply chains and their business around the knowledge they have open access to the U.S. market and to a lot of other markets around the world. Let's not forget we still do a fair amount of business even with markets we don't have free trade agreements with. About 25% of our exports go to countries other than the United States.
Other markets are still quite important. In fact, if you're looking at China, if you're looking at Latin American countries, some of them are growing very fast and a lot of Canadian companies are investing in growing these markets.
What would happen if we put more barriers in place? It's a very good question. I'd rather not think about it, to be honest with you. I think Canada has benefited a lot from open access to other markets, especially with the United States. Getting those free trade agreements in place with the U.S. and Mexico has allowed Canadian companies to have access to a much wider, much broader market.
Canada was the only G7 country to create manufacturing jobs during the 1990s. A big reason for that was the fact that we had privileged access to the U.S. market. The low dollar was another reason, but it was by and large due to the better access to the U.S. market.
