Some of our members are integrated. As a member we'll have Imperial Oil chemical, but they're integrated with the upstream oil and gas. Most of the chemistries we do produce come from natural gas liquids. The reason we we have our clusters in Alberta, Ontario and Quebec is that we're close to that feedstock. You'll find a number of companies, like Dow, NOVA, Inter Pipeline, that are based in this chemistry cluster in Alberta, and they're pulling from the natural gas feedstock available.
The companies are so deeply integrated in terms of Canada-U.S. that those chemical products will cross the border several times before they're finalized and prepared for that next step in terms of downstream products. There is a lot of back and forth, which demonstrates the high numbers in terms of the export-import trade.
