What Makes Long Branch's Water Unique?
Local geology and source profile
Long Branch (a southwest Etobicoke waterfront neighbourhood at the Toronto-Mississauga boundary — the Long Branch community on the Lake Ontario shore at the very southwestern tip of Toronto near Port Credit, a historic lakefront neighbourhood of post-war bungalows and newer infill townhouses along the Long Branch Avenue-Lakeshore Boulevard West corridor, adjacent to the Long Branch Park and the Colonel Samuel Smith Park waterfront, one of Toronto's more affordable and community-oriented waterfront neighbourhoods at the Etobicoke Creek and the Mississauga city limit, served by the 501 and 508 Lakeshore West streetcar lines) receives its drinking water from the City of Toronto, drawing from Lake Ontario near the Lakeview Water Treatment Plant corridor. Water is treated using ozonation, biofiltration, UV disinfection, and chloramination, meeting all Guidelines for Canadian Drinking Water Quality (GCDWQ) standards. Hardness is 257.5 mg/L (15.0 gpg) — classified as very hard by Health Canada, among the hardest in the Toronto distribution system.
Long Branch draws from Lake Ontario at the southwest Toronto shoreline boundary — at this location, the Lake Ontario water is served by the Lakeview supply corridor, drawing from a Lake Ontario intake adjacent to the Credit River and Port Credit area. The 257.5 mg/L and TDS 675.6 mg/L are higher than the standard Toronto range (229–240 mg/L), reflecting the anomalously harder Lake Ontario water at the southwest Toronto distribution extremity, consistent with the broader pattern of harder Toronto sub-zones at the outer distribution pipeline limits. The Lake Ontario water here carries dissolved Silurian and Devonian carbonate from the Great Lakes basin.
At 257.5 mg/L, Long Branch residents face persistent scale challenges — monthly to bimonthly kettle and showerhead descaling is typical. The City of Toronto provides water quality information at toronto.ca/water. Health Canada lead service line precautionary guidance applies to Long Branch's post-war bungalow housing stock for pre-1955 properties in the historic lakefront Long Branch community.
Geology & Source: Supplied by City of Toronto or Region of Peel from Lake Ontario via the Lakeview Water Treatment Plant — the Long Branch southwest Etobicoke waterfront distribution sub-zone carries very hard water at 257.5 mg/L (15.0 gpg), among the hardest Toronto sub-zones, reflecting the southwest Etobicoke Lake Ontario boundary supply.
