Val,

I agree that Canada needs to give high priority to developing markets for our goods and services in East and South Asia and in the EU countries (including the UK).  

I also agree that there need to be limits to the concessions that we are prepared to make (and there need to be compensating concessions Canada needs to demand in return) and, to that end, we need to be prepared to end negotiation if the US is unreasonable and refuses to abide with these limits.

Where I differ with you is that I expect that termination of free trade with the US would be painful and that the especially painful period of transition would be lengthy. Even so, we need to be resolute during the negotiations and prepared to endure such pain rather that submit to an inequitable treaty.
