Taylor-Massey Water Hardness & Quality Report (2026)

Taylor-Massey (a neighbourhood in East York along the Taylor-Massey Creek corridor — centred near the Danforth/Warden area, adjacent to the East York civic centre and the Michael Garron Hospital, a residential community of post-war bungalows and apartment buildings in the lower Don Valley–East York plateau zone with a diverse mix of South Asian, Caribbean, and established East York families in the Taylor Creek–East General corridor) receives its drinking water from the City of Toronto, drawing from Lake Ontario via the R.C. Harris 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 237 mg/L (13.8 gpg) — classified as very hard by Health Canada, consistent with the East York supply corridor.

Taylor-Massey receives R.C. Harris plant Lake Ontario supply through the East York distribution network — the same characteristically very hard Lake Ontario source (dissolved Silurian and Devonian carbonate from the Great Lakes basin) as all Toronto boroughs. The 237 mg/L is consistent with the adjacent Danforth East York (238 mg/L), Victoria Village (237 mg/L), and Leaside-Bennington (237 mg/L) in the same East York distribution corridor.

At 237 mg/L, Taylor-Massey 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. The City of Toronto provides multilingual water quality information at toronto.ca/water. Health Canada lead service line precautionary guidance is strongly applicable in the neighbourhood's post-war housing stock for pre-1955 properties along the Taylor Creek residential streets.
