The trade balance has changed for Canada principally, I would say, because the exchange rate has moved so significantly over the last five or six years.
Our exporters were benefiting from having the dollar at around 70¢ until about 2005. At that point, the Chinese entry into the world economy began to impact commodity prices, and the dollar soared. We're now at par, so adapting to the exchange rate is one of the critical challenges for our export community, and it's something that the TCS is well aware of. That's one factor in changing the trade balance.
Of course, the U.S. has gone through a financial crisis and has had a very slow recovery over the last three years. That has meant much weaker export demand in the United States, so that's another factor. I also think that we were probably slow to seize the opportunity of diversification of our trade over the last decade or so, although we're now catching up. There are a variety of factors, a lot of them external to Canada.
The strong dollar.... We've had the benefit of strong commodity prices, so in those sectors the trade balance is in very nice shape. You're seeing strong export potential out of the resource sectors, but for a lot of the rest of the economy, the combination of the U.S. financial meltdown and slow recovery and the dollar effect have contributed.
I think the NAFTA has actually preserved our market share or our presence in the U.S. It was really a critical piece to ensure we were still a player. It would have been very hard for us to push back in Buy America, for example, if we didn't have a free trade agreement with the United States.
Our challenge with the Americans is actually to go deeper, so we're quite pleased that the government is working with the Obama administration in looking at expanding the security perimeter, dealing with regulation, and going beyond NAFTA, which was very much a tariff-based agreement, and getting into the quite hard issues of non-tariff barriers. I think that's actually preserved our market presence rather than hurt us.
