What Makes New Toronto's Water Unique?
Local geology and source profile
New Toronto (a historic southwest Etobicoke neighbourhood along the Lake Shore Boulevard West corridor near the Islington Avenue intersection — the former independent Town of New Toronto (incorporated 1913, amalgamated into Toronto 1967), one of the Lake Shore's historic factory towns with its landmark former Goodyear Tire and industrial plant sites along Lake Shore, a working-class Etobicoke lakeshore community of post-war bungalows and war-time housing now rapidly transitioning to condominium redevelopment, adjacent to Marie Curtis Park and the Etobicoke Creek mouth at Lake Ontario, home to the historic Lakeshore Lions Club and the Long Branch–New Toronto lakeshore heritage) 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 is 232.5 mg/L (13.6 gpg) — classified as very hard by Health Canada, consistent with the standard southwest Etobicoke supply corridor.
New Toronto receives F.J. Horgan plant Lake Ontario supply through the southwest Etobicoke lakeshore distribution — the same characteristically very hard Lake Ontario source (dissolved Silurian and Devonian carbonate from the Great Lakes basin) as all Toronto boroughs. At 232.5 mg/L, New Toronto is notably harder than the anomalously softer Etobicoke sub-zones inland (Etobicoke West Mall 190 mg/L, Humber Summit 173 mg/L), reflecting the lakeshore distribution proximity to the F.J. Horgan plant at this Etobicoke waterfront corridor.
At 232.5 mg/L, New Toronto residents face persistent scale challenges — monthly to bimonthly kettle and showerhead descaling is typical. The City of Toronto provides multilingual water quality information at toronto.ca/water. Health Canada lead service line precautionary guidance applies to New Toronto's wartime and post-war bungalow housing stock for pre-1955 properties in the established Lake Shore–Islington area.
Geology & Source: Supplied by City of Toronto from Lake Ontario via the F.J. Horgan Water Treatment Plant — the New Toronto southwest Etobicoke distribution zone carries very hard water at 232.5 mg/L (13.6 gpg), consistent with the standard southwest Etobicoke supply corridor.
