Canada is already presenting a fragmented stance to the US regarding trade re-negotiations:  

Our ambassador is recommending bilateral talks, while PM Trudeau, after speaking to Mexico's President, was re-affirming the importance of tri-lateral talks.

Canada relies very heavily on US trade for our economic health, especially in the auto industry, and on their military to keep us safe, while we under-spend our NATO commitment by half.

Not a strong bargaining position for Canada, at all.

To make matters worse, Trudeau's just publicly insulted President Trump by proclaiming his support for the protests against the President on Jan 21, thanking the protesters and saying they were an 'inspiration' to his government. 

Do not think that Trudeau's damaging remarks have gone un-noticed in Washington. 

Short of a major damage-control campaign / charm-offensive, since Trudeau's handlers obviously can't control him, they should at least make sure he becomes un-seen and un-heard.
