When you say “Canada's auto industry” in a global setting like that, you're referring to other global companies that are actually not based in Canada. It would be the decision of companies that manufacture in Canada, like General Motors, Ford, Chrysler, Toyota, Honda—the five global companies that manufacture light vehicles in Canada—to show up at the shows and show their new products.
One of the structural weaknesses even of our auto industry, which is a rare example in Canada's case of a high-value-added, innovation-intensive industry that has succeeded here, is that we are 100% dependent on foreign investment, on companies that came here and established branch plants. Those branch plants are important, but it does mean for our overall economy that we don't have the full capacity to undertake innovation development of new products and so on.
I can't comment on why the companies wouldn't put up booths at those trade shows. It could be that they don't see any significant opportunities for selling their product in Japan. Remember, Japan has an effectively closed auto market. It's difficult to identify precisely why that is--how much of it is due to government regulations, non-tariff barriers, restrictions on the establishment of dealerships and other marketing, and how much of it is perhaps due to a nationalistic or patriotic mentality on the part of Japanese consumers, who won't consider imported products.
