Economic Structure of Canada Historically,...... half of document ...... for the quality of Canadian drinking water within their jurisdiction, provincial water authorities are responsible. In order to provide municipalities with a clean, safe and reliable supply of drinking water, the guidelines establish the basic parameters that each water system (public, semi-public and private) should aim to achieve. In addition to federal guidelines, provincial and territorial water authorities impose water quality and drinking water standards. To ensure provincial water quality regulations, municipal water utilities are accountable and goals are met. To safeguard drinking water supplies, more stringent water quality regulations have been enacted, and the costs of maintaining water quality standards have increased considerably. For example, capital costs have been estimated at more than $800 million to meet Ontario's water quality regulatory requirements.
