That's a subject we could talk about for some time. We know, for example, and the figures support it, that at the beginning of the 1970s there were about 40 refineries in Canada, and now only about 19 are left. One of them will probably disappear soon. As for refinery capacity, it has not really diminished. The players who have remained are therefore better integrated.
Obviously, all of the environmental rules have been positive. As I was in east Montreal during the 1970s and 1980s, I can tell you that air quality was a serious problem. That's not the case anymore, and it's not simply because the refineries have disappeared. The players that remain today are on the leading edge of technology and apply excellent environmental measures. They can compete with all the other refineries that are still on the market.
We can talk about the past, but what is important to know is that we still have a good industrial framework in the east which still allows for development. The key to success is to have options in terms of raw material.
