Again, we look at the macro situation across the whole country with respect to the capacity that exists within the refining sector, as well as with the oil and gas operators. Of course, they operate on two levels. They operate at the level of the upstream and the downstream, as I mentioned earlier.
From our perspective at this point in time, and certainly over a prolonged period of time, the economic environment has been such that the capacity has been lower than the actual throughput, which means that reserve capacity exists within the refining sector to meet increased demand, and that demand hasn't existed, so there has been underutilization—which I think was part of the opening presentation I made.
In terms of the rationalization, certainly there has been a trend going on for at least 30 years that has seen rationalization in the refinery sector in Canada, and of course around the world, as I pointed out.
The unfortunate side of refineries is that Canada has gone from some 40 refineries to about 16 at this point in time, and that has occurred over the last 30 years. Over that period, while capacity has increased, the actual number has decreased and their economies of scale have substantially increased. A number of those previous refinery closures or conversions have existed and there hasn't been a requirement under any act for the government to act or to intervene into the market-based policy framework that we have for the energy economy in Canada.
