Americans have been getting a greater deal on Canadian goods this last year. Loonie was 76 and now 68 . The tariff just puts the goods back to the same old range. If I was an American business and need that foo foo valve from Canada I would still buy it to keep the wheels turning. Now our Wizards up here just added tariffs on USA foo foo valves and our weak Loonie already made it more for my business purchase, but now it is 15 % more.  I think my morning stooper theory is correct and Tenters feel free to correct me .
