The decline in the visits of Canadians to the USA in those years was directly the result of the decline in the value of Canadian dollar resulting exclusively from the serious drop in OIL prices.

Because America is a vibrant, exciting place filled with wonderful people and places.  Further their business and innovation climate leaves Canada in the dust.  

Further capital is flowing OUT of Canada more than it is flowing in.  Where is that capital going? You look it up.
