US President Donald Trump discussed absorbing Canada into the United States on several occasions in his first Oval Office meeting with Carney last week.
MSNBC's Katy Tur was shocked as Canadian journalist Stephen Marche mocked Americans and warned that war between his nation and the US could break out soon.
The meeting comes days after Carney's Liberal Party won the April 28 election on promises to tackle Trump and create a new bilateral economic relationship.
