Markham's Only Source of Drinking Water is Lake Ontario

Clean drinking water is one of our most precious resources and in Markham we are fortunate to have access to an abundant supply. However, Markham does not have direct access to Lake Ontario and must rely on a water supply, water treatment, and wastewater treatment from outside its municipal borders. Fresh water is essential to all aspects of our lives and it is important that we all take part in protecting our fresh water source. To ensure clean, reliable water for tomorrow, we need to start protecting it today.
