US President Donald Trump halted all trade negotiations with Canada earlier this week over an advert in which former President Ronald Reagan says tariffs "hurt every American". The ad, sponsored by Canada's province of Ontario and released last week, features excerpts of an address Reagan gave in 1987 focusing on foreign trade.

Overall, the ad’s message aligns with most of Reagan’s remarks, which, over five minutes, expressed a dim view of tariffs. Reagan said he believed that in the long term, tariffs would lead to trade wars and hurt Americans.

The 1987 radio address by the former U.S. President Ronald Reagan at the centre of a new U.S.-Canada row was a defence of free but fair trade in which he explained his decision to put duties on Japanese goods in a trade dispute.
