I can't tell you what will happen or would happen. We've never used this authority. Whether we ever will, I have no idea. That will be determined by the government of the day.
This provides the authority to make that discrimination, provided we meet the test of ensuring consistent and common environmental and health outcomes. We can't use it willy-nilly. We would have to use it only if justified for the purpose of achieving a common outcome.
Again, the air quality, the Toronto-Windsor corridor--we're trying to achieve the same quality of air everywhere. If the air quality is worse in one place, it may make sense to have different emissions standards for the people in that area, with the objective of ensuring that the people in that area have the same air quality as the people in the Yukon and northern Saskatchewan. The outcome has to be the same.
