The markets have been  trending optimistic since Trump won the election. The economy has been humming along for at least 18 months. Now that Yellen is planning to increase the interest rates, now that Trump will release his first wish- list budget and the fact that the roll out on the revised Obamacare has not gone well and may be worse, the signs are not optimistic for the American or Canadian economy. 
Trump cannot grow an economy by restricting free trade. He can do it by starting a massive infrasture  plan and/or sending Americans  to war. That was the template after the Second World War. Trump wants to grow the economy by 4%. He'll be fortunate not to see a contraction with his philosophy.
