Yes, I think a regional approach has some merit from the standpoint, as Dr. Hrudey mentioned, of Canada not being a homogenous place. Water challenges across Canada are certainly different and unique: there are arid places in Canada, and the Atlantic region is certainly not an arid place. So to have regulations that would deal with different regional contexts has some logic, especially if they follow the same spirit of a drinking water safety plan and having checks and barriers in place. We could then deal with the subtleties of regionalization a little more easily.
