It's hard to predict what will happen. Obviously, if leave is granted, the Supreme Court of Canada will be considering only the three provisions, but what the court does in making its decision may have an effect on the other ones. The purposes of PCEPA have been upheld as constitutional by the Ontario Court of Appeal, so even though section 286, the “purchasing” provision, wasn't available, it still has an influence over that. The Supreme Court of Canada's decision in N.S. will have an overflow effect on the other decisions that are coming forward.
