Description: As the Canadian delegation arrives in Washington ahead of Prime Minister Mark Carney's Tuesday meeting with U.S. President Donald Trump, three sources tell CBC News and Radio-Canada they're aiming for partial relief from steel tariffs that could create a framework for how other tariffs could also be lowered. Former Canadian ambassador to the United States David MacNaughton warns Canadians to have 'measured expectations' for the meeting, and advises that Canada should still avoid making a 'bad deal quickly.' Plus, Conservative House leader Andrew Scheer makes the case that Carney is already failing his promises for U.S. negotiations.
