Justin , our PM, can demand what he wants, can throw every politically correct "want"  that he desires  into the negotiation pot ...but, at the end of the day,  President Trump will do whatever is good for the USA , brushing aside Canada's  PC " wants" ....hopefully the best Canadian negotiation brains will be looking after the economic matters and not on the government's PC "wants".

Trump intends the USA to become lean and mean....Canada will have to become leaner and meaner in order to survive.
