Historically, industrial use, including petrochemicals, has been a significant source of Canadian demand.
A significant factor in the market is that petrochemical producers have a decent amount of flexibility in what feedstock they use, and lately, just because of relative prices of different NGLs, they have been shifting away from propane a little bit.
The numbers show that industrial demand is about 40%, commercial about 20%. Then, when they break out petrochemical non-energy demand, it is about one-fifth of Canadian demand. Of course, one factor is residential. Although about 9%, it is heavily weighted to the wintertime, so it would be a larger share during the cold periods.
