Understanding Vaughan's water

Where does Vaughan's water come from?
Vaughan gets its drinking water through York Region, sourced from Lake Ontario and treated at City of Toronto and Region of Peel plants. It meets all safety standards, but many homeowners notice residual chlorine, hardness and occasional sediment or taste issues, especially in older areas and on private wells.
