An article in the Wall Street Journal (Dec 8, 2011) describes the US-Canada border delays as costing the Canadian economy $ 15.8 billion.  A new plan is expected to simplify clearance, with goods entering by ship to a US or Canadian port requiring only one clearance at the port of entry for use anywhere in the US or Canada. Will the simplified border crossing create competition across ports in the US and Canada that will reduce overall supply chain costs ? Which industries can be expected to move across borders in response to this change ? How will the “buy American” provisions in many US spending bills be impacted by the simplified trading system ?
