Someone suggested putting a tax on oil exports to counter their lumber, etc. restrictions, but then they would put a tax on autos, Bombardier, etc. etc. and Canada would be no forwarder.
I guess that someone would have been me Q. Having worked in the oil industry I'm sure that you know what a gate valve is. If Bush wants to up the ante you turn off a big one in the pipeline flowing south for 24 hours. You then turn it back on for 24 hours and ask Bush if he wants to remove those taxes. If not turn it off for another 24 hours etc. add infinitum until you attract someones attention. I'm betting that it wouldn't take long!
