Prime Minister Justin Trudeau will try to strengthen Canada’s trade and security ties over the next five days with European allies also facing threats from U.S. President Donald Trump over their economy and sovereignty.

Trudeau is heading to Paris and Brussels starting Saturday — just days after Trump agreed to pause tariffs on Canada until March 4.

Roland Paris, a former adviser to Trudeau, says it’s important for Canada and the European Union (EU) to share notes about how to deal with Trump during this time of great uncertainty and co-ordinate if he does unleash punishing tariffs against them.
