Sunny ways needs to up his game as nice hair and firm handshake are not the way to deal with a bully. First our PM needs to understand what a Canada First strategy is. He has been in the trough of US and China for so long he forgets he is a Canadian. If they want to respond make all gas shipments to the US at the international price. Canada is the second largest export of Natural Gas in the world, but gets a one fifth of its vale, that is for everybody reading 20 cents on the dollar. The US has been burning our gas for so long they think they own it. It will take them years to respond, in the mean time we collect the value and build Clarks LNG export terminals as well as reverse Irving import terminal on the Bay of Fundy. We can also back date the charges as ramp time to recover all the softwood lumber tariffs plus add a  100% to cover the salary and pensions of the political class who work on the file. Time to play hard ball with the Donald. If he doesn't like it, next is Canada Oil.
