A telling excerpt from the PMO statement:
"They [Canada's negotiators] have worked hard, in good faith, to defend the interests of Canadians throughout these negotiations up until the very last minute. However, last-minute changes in the U.S. proposed terms were unfair, uneconomic, and called into question the reliability of any deal."
I sense that Team Donnie Dementia can't keep themselves from renegotiating their own deal before it's even made.
