Let's be clear.  Biden doesn't speak for the US.   The US may not start producing additional GHG emissions, but they sure as heck can continue producing the same amount for years to come.  That puts Canada at an obvious disadvantage.     The other piece to consider is that Wynne, is absolutely crazy and does not have the support of Ontarians.  It's interesting that Manitoba is fine with introducing a carbon price but realistically they have next to 0 contribution to Canada.  A big city in Ontario contributes to the Canadian economy more than most of the smaller provinces.
