I completely agree. The issue of price and linkage is really important. If the Canadian price were significantly higher, then what we would see here in the U.S., if buyers would be buying U.S. allowances and significantly bringing up U.S. prices, that would not be politically acceptable on the U.S. side. In the same vein, a huge outflow of Canadian investment into the U.S. to buy these allowances would also not be politically acceptable on the Canadian side. I'm just guessing, but that would be my take on that. I don't think two significantly different prices would be politically acceptable for either country.
