Because the alternative would be to make some annoying demands of the auto industry, of various police services, and of CP Rail and the ports. That's a lot of political capital to spend (or burn) on a lot of different groups, and would likely anger a lot of bases of power and financial support, for some citizen benefits that won't really pay off in the short term.
