Source: Canada Taking Nothing for Granted About Tariff Exemption

Canada is taking nothing for granted when it comes to a possible exemption from U.S. tariffs on steel and aluminum, especially given President Donald Trump's approving comments about trade wars on Friday, a well-placed Canadian source said.

The source, speaking on the condition of anonymity, also said Ottawa was looking at what sanctions it might impose on the United States in case it was targeted by the steel tariffs. The Canadian government said on Thursday it would retaliate if need be.
