The price increase due to tariffs will definitely " hurt" 
Consumption could be cut.
Especially if Canada devalues currency to keep our export channel open.  
Hard to see any consumer win in this for Canadians. 
By and large we are price " takers" not price "makers".
I'm not certain Americans will feel much impact at all, other than their funny northern neighbour has become a tourism bargain , again.
As for Chinese goods flooding our market and filling the gap... say good bye to what remains of Canadian manufacturing.
