Right now, the establishment of interprovincial barriers for trade is significant. There's been some work done between Alberta and B.C. The barrier has been quantified as a $4 billion barrier, and that's what they're trying to tear down. Interprovincial trade barriers were recently quantified at $80 billion per year. This has been acceptable in the north-south approach to trading that we've had.
If we're going to combine the capacity and capability of our manufacturing sectors across the country, we have to tear those barriers down, whether they be trade and regulation, or simply the ability to move freight. You can't move trucks across this land currently in the springtime when we have breakup. So we have to encourage the railways to allow interprovincial shipments. They're much more interested in moving from the port into Chicago, where they can move Wal-Mart products from China and make a lot more money.
So there's some interest that we have to have interprovincially on regulations and on infrastructure on interprovincial transportation.
