Andrew, 

You make the important point that a major priority for Canada in all negotiations regarding foreign trade is to lessen our current over-dependence upon the US market.

This has been Canada's goal since the 1970s and we have not been particularly successful to date.

Recently, however, we have concluded the comprehensive trade deal with the EU which effectively gives Canada preferred access to EU markets to that that the US has.  

With the US drawing back from East Asian trade relationships and Australia and New Zealand making major strides to cement their trading access to Asian markets, Canada needs to give priority to achieving bi or multi lateral trade deals with Asian countries where practice.
