Here's what you need to know about the tariffs deal and what happens next. The American tariffs on Canadian steel and aluminum — 25 per cent and 10 per cent, respectively — disappeared as of today. Trade in aluminum between Canada and the U.S. is around $15 billion a year, and 84 per cent of Canada's aluminum is exported to the Americans. Freeland said if the tariffs come back, they only would target the specific offending material — meaning steel won't be affected by aluminum imports, and vice-versa. Now that relative peace has been established, those Canadian tariffs dissolve too.
