I've seen this article repeated in the NatPo[0], and more-or-less copied in the HuffPo[1], but no where else. I suspect this is mostly fearmongering. The US market is so much bigger than Canada's that most investment portfolio recommendations for Canadians include double-digit proportions of US equities and bonds. And if they are weighted towards energy, I can see why they'd shift south of the border.
