your definition of free trade is not the one that is in effect. the one that is in effect stats that NO tarrifs shoul dbe in place when moving goods over the borders, if you want to argue about it the by all means good ahead, but these are the facts, the amercan gov threw an unfar level of taxes on canadian soft wood lumber. to the point where ist being taxed over 30% now that is unfair. Canada appealed to the WTO which ruled in canada's favour, NAFTA is also doing its own investigation and is likely to rule in favour of canada. If your definition was correct both of these international bodies would not be ruling in canada's favor.

and find me a source for your definition of free trade i am very curious to see one that states that a government can put what ever tax they want on product coming in to the country.
