We can only assume the railways fought against it and that's why we have these exclusion zones. This attempt essentially maintains the C-30 provisions. Essentially there is a piece of Canada in the Prairies that could benefit from this, much as they did through Bill C-30. I think this has just found a different and more creative way of accomplishing the same thing. I assume if it were more opened up in central Canada or in eastern Canada it would simply force the railways to be more competitive with one another, and they don't want that.
