Moving in that direction, I agree with Dean Martin: you're already starting from a situation where Canada's tax system, by the standards of the world as a whole, is not terribly competitive. You would be moving in the opposite direction, in the wrong direction, making it less competitive.
What would that mean? It would mean that Canada would be a less attractive home for multinational firms, number one. Number two, even the firms that are here will wind up less productive in the long run, so you wind up with lower national incomes. I don't understand why a country would want to go in that direction.
