probably complications in the talks with the EU considering the size of things. From what I can see there are proposals for EU-Canada trade agreements starting with an FTA but I suppose there is so much. I think most people are looking for a transatlantic NAFTA-EU agreement, or possibly with the whole of the Americas if the Americas thing happens, I know the EU is making deals with both south American communities and wants a full deal with the whole contitnent, so that plus a merge with NAFTA...
