Kingsview Village-The Westway Water Hardness & Quality Report (2026)

Kingsview Village-The Westway (a residential neighbourhood in west Etobicoke, Toronto, near The Westway and Martin Grove Road — an established post-war community of bungalows and semi-detached homes adjacent to the major Highway 27–Westway commercial corridor, home to a diverse mix of European immigrant and South Asian communities) receives its drinking water from the City of Toronto, drawing from Lake Ontario via the F.J. Horgan Water Treatment Plant. Water is treated using ozonation, biofiltration, UV disinfection, and chloramination, meeting all Guidelines for Canadian Drinking Water Quality (GCDWQ) standards. Hardness in this distribution zone is 240 mg/L (14.0 gpg) — classified as very hard by Health Canada, with TDS of 610 mg/L, consistent with the west Etobicoke distribution corridor.

Kingsview Village-The Westway receives F.J. Horgan plant Lake Ontario supply through the west Etobicoke distribution network — part of the same characteristically very hard Lake Ontario source (dissolved Silurian and Devonian carbonate from the Great Lakes basin) supplying all Toronto boroughs. The 240 mg/L is consistent with the adjacent Willowridge-Martingrove-Richview (239 mg/L) and Stonegate-Queensway (240.5 mg/L), confirming the very hard supply character throughout the west Etobicoke corridor.

At 240 mg/L, Kingsview Village-The Westway residents face persistent scale challenges — kettle and showerhead descaling every one to two weeks is typical. Hot water tanks accumulate scale and benefit from annual inspection and flushing. The City of Toronto provides water quality information at toronto.ca/water; the neighbourhood's established post-war housing stock warrants lead service line review for properties built before 1955 through the City's replacement programme.
