Canada fucking hates the US right now and are actively in discussions to deepen their relationship with China, and cut back on their relationship with the US.
I don't blame them.
I mean the problem with the bed Canada has made is they don't really get a choice.
Canada is actively pursuing more pipeline capacity to the west coast, in order to sell more oil to China.
However, it's also true that if the US builds a new pipeline to the Canadian border, Canada will happily fill it with heavy crude.
