Writing in my fortnightly Globe column I make the case that commentators can harrumph all they want at Kevin O’Leary’s plan to discipline the provinces for damaging Canada’s national economic prospects. He is doing nothing the founders of Canada didn’t plan and allow for. His rhetoric may be a little over the top, but he is not wrong to say that Ottawa has the tools to discipline provinces who act contrary to the national interest (including via withholding some transfers) and that they should be used when circumstances warrant.
