Summary

Mark Wiseman, Canada's ambassador to the US, says that trade talks between Canada and the US collapsed due to disagreements over deal terms, with the Canadian side believing it had agreed to certain concessions that were not reflected in written documents. The negotiations broke down on Friday, prompting a 50% tariff on $20 billion in Canadian goods and a promise from the US to escalate if Canada retaliates. Wiseman likened the situation to a handshake agreement where the terms are later revealed to be different from what was agreed upon, leading to a breakdown in trust. The collapse of talks has led to volatility in currency markets, with the Canadian dollar weakening by 0.5%.

Narrative

“We’re just not willing, at the end of the day, to accept terms that were unfair, uneconomic and actually, you know, called into question the reliability of the deal,” Wiseman said. “Because you know one of the things that you’d hate to see happen is you agree on something and then, after agreeing to it, it gets undermined.” — With assistance from Matthew Burgess.

deal → say → Canada

he → protect → Canada
“Those that want to do business in Canada, be it digital or anything else, must respect that fundamental reality.” asserted
it → want → reality

that → say → talks
