Grosso modo, there are two buckets of clean drinking water standards. There are national standards, and then provinces and territories have their own standards that apply above and beyond national standards. I think in the province we're in today, post Walkerton, there's a considerable increase in standards for clean and safe drinking water, potable water and access to water.
There are, in this country, geographically specific standards that are provincially and territorially created. Then there's a national minimum standard that creates a minimum standard for all Canada's drinking water.
