U.S. President Donald Trump says the days of the U.S. being taken advantage of in trade deals are over.

Trump also referred to the ongoing talks to upgrade NAFTA by saying a message had been conveyed to Justin Trudeau that the United States “will agree to a fair deal or there will be no deal at all.”

The comments come after Prime Minister Justin Trudeau called Trump’s use of a national security clause to justify the new tariffs as “totally unacceptable.”

“For 150 years, Canada has been the United States’ most steadfast ally,” Trudeau explained.

Later, Trudeau used a hockey analogy to express his distaste for Trump’s decision to put steep tariffs on U.S. import steel and aluminum as of Friday.

“We’re polite as Canadians but we’re also firm. When push comes to shove we know how to use our elbows in the corners in the hockey rink.”

As part of Canada’s response, Foreign Affairs Minister Chrystia Freeland says Canada will impose dollar fordollar countermeasures on the Americans July 1st.

The tit for tat comes a week before Trump is to attend the G7 summit Trudeau will be hosting in Quebec.
