Canada's total capacity has gone up. For example, we had 30 refineries in 1990. However, at present, 19 refineries are producing more than what was produced in 1990. Canada's refineries have increased their production by about 5% over the past 15 years. Therefore, the relevant factor is not the number of refineries, it is their production capacity.
