Dan Mitchinson: US correspondent on US President Donald Trump imposing 50 percent tariffs on Canada

US President Donald Trump on Tuesday imposed 50 percent tariffs on most Canadian goods, and concerns have been raised about the economic implications. The new tariffs would exclude energy products, potash, fish and critical minerals, but would cover goods that had previously been protected from import taxes by the United States-Mexico-Canada Agreement. US correspondent Dan Mitchinson says Canadian officials haven't said much, but there's speculation Canada could raise tariffs on their own goods.  LISTEN ABOVESee omnystudio.com/listener for privacy information.
