U-S tariff on auto imports would be ``painful'' for Ontario: Former CAW President

The former national president of the Canadian Auto Workers union says a U-S tariff on auto imports would be ``painful'' for Ontario and the country's economy.

Ken Lewenza says U-S President Donald Trump's comments about possible auto tariffs have cast uncertainty on the industry as carmakers plan for new vehicle models five years in advance.

Lewenza warns there would be an economic disaster if the worst case scenario took place and auto companies started exiting Canada.

Trump has threatened to impose a 25 per cent tariff on auto imports from Canada.

Canada's auto sector delivers roughly 80-billion dollars in economic activity
