So there ends up being only one price regardless of where the oil is produced or consumed.
Export capacity is limited. People in, for example, Minnesota or Illinois, which are mostly on Canadian feed, may very well see no difference as their refineries are configured basically to mostly take Canadian feed, and the supply chains cannot easily redirect that production elsewhere.
