I must admit I did not see what this guy is predicting as a possibility:

Sun News is a bit alarmist at times of course. I would have though that the Free Trade Agreement would prohibit the US from a $40 per barrel tax (environmentally motivated or otherwise) on Canadian oil sent down the pipeline. However, I am no expert on the FTA.
Anyone in the know here?
