Justin Trudeau plans to issue Canada's own tariffs in response to the U.S.

Eh?

Justin Trudeau, the Prime Minister of Canada, took to Twitter to express his - and Canada's - feelings about the steel and aluminum tariffs that were announced by the U.S. on Thurs., May 31. 

American tariffs on Canadian aluminum & steel are unacceptable. As we have said, we will always stand up for our workers, and today we're announcing retaliatory measures to this attack on our industry.

Trudeau, in a series of tweets, announced Canada's intention to implement its own tariffs in retaliation for the steel and aluminum tariffs. 

Canada will impose tariffs against imports of steel, aluminum and other products from the US - we are imposing dollar for dollar tariffs for every dollar levied against Canadians by the US.

These countermeasures will only apply to goods originating from the US and will take effect on July 1, and will remain in place until the US eliminates its trade-restrictive measures against Canada.

Canada plans to issue tariffs on U.S. goods starting on July 1. While it's not clear what will be affected yet, Trudeau's made himself very clear. What Canada loses on import tariffs, it will earn back from the U.S.

Canada will also challenge these illegal & counterproductive measures under NAFTA Chapter 20 and at the WTO. It is simply ridiculous to view any trade with Canada as a national security threat to the US and we will continue to stand up for Canadian workers & Canadian businesses.

Trudeau isn't the first to respond to the U.S. tariffs. Mexico has also stated that it intends to fight back against the U.S. by implementing its own tariffs. The EU has also spoken out, saying that it will be considering tariffs for U.S. imports.

The "EU has already come up with numbers and products," said Hugo Perezcano, deputy director of economic law at the Centre for International Governance Innovation.
