What Makes L'Amoreaux's Water Unique?
Local geology and source profile
L'Amoreaux (a residential community in north Scarborough, Toronto, centred on the L'Amoreaux Park area near McCowan Road and Finch Avenue) receives its drinking water from the City of Toronto, drawing from Lake Ontario via the R.C. Harris Water Treatment Plant on the Kingston Road lakeshore. Water is treated using ozonation, biofiltration, UV disinfection, and chloramination, meeting all Guidelines for Canadian Drinking Water Quality (GCDWQ) standards. Hardness in L'Amoreaux's distribution zone is 233 mg/L (13.6 gpg) — classified as very hard by Health Canada, consistent with the broadly very hard supply characteristic of Toronto's north-Scarborough distribution zones.
L'Amoreaux's high hardness reflects the supply characteristics of Toronto's northeast distribution corridor, where Lake Ontario water from the R.C. Harris plant travels through an extensive transmission and secondary distribution network to reach these elevated north-Scarborough communities. The Lake Ontario source — carrying dissolved Silurian and Devonian carbonate minerals from the broader Great Lakes watershed — measures 233 mg/L in L'Amoreaux's specific sub-zone, one of the consistently hard north-Scarborough areas alongside Malvern, Woburn, and Willowdale East.
At 233 mg/L, L'Amoreaux homeowners face persistent scale build-up on kettle elements, showerheads, and inside hot water tanks — kettle descaling every one to two weeks is common. Hot water tanks benefit from annual inspection and flushing to maintain heating efficiency and prevent premature failure. A whole-home water softener is a worthwhile investment at this very hard level. The City of Toronto provides zone-specific water quality information at toronto.ca/water, and residents are encouraged to review hardness data for their specific distribution sub-zone.
Geology & Source: Supplied by City of Toronto from Lake Ontario via the R.C. Harris Water Treatment Plant — the L'Amoreaux (north Scarborough) distribution zone carries very hard water at 233 mg/L (13.6 gpg), reflecting elevated carbonate mineral content in Toronto's northeast supply corridor.
