As you know, we get propane from two sources. First is the barrel; 15% is from refineries across Canada in nine provinces. One of those provinces does not have refineries. But 85% of the production comes from natural gas. It's extracted from Alberta. Edmonton has one fractionation centre. The next one is Sarnia. Probably most of the fractionating is done in Edmonton, and then it is railed into Sarnia, where it's stored. There is some fractionating done in Sarnia also. Then it's railed or trucked into the provinces for most of the distribution.
