Kennedy Park Water Hardness & Quality Report (2026)

Kennedy Park (a mid-Scarborough neighbourhood centred near Kennedy Road and Eglinton Avenue East — a diverse post-war community of bungalows and apartment towers in the Kennedy Road–Eglinton corridor, with a significant Caribbean, South Asian, and East African immigrant population, adjacent to Eglinton Square shopping centre and the future Eglinton Crosstown LRT 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 155 mg/L (9.1 gpg) — classified as hard by Health Canada, consistent with the lower-hardness sub-zone anomaly documented across several Toronto–Scarborough distribution zones.

Kennedy Park's 155 mg/L matches the consistent cluster of lower-hardness Toronto sub-zones (Bayview Village 154.5 mg/L, Agincourt North 154.5 mg/L, Dorset Park 154.5 mg/L, Weston 155 mg/L) — significantly softer than the standard central Toronto supply of 230–240 mg/L. The Kennedy Park distribution sub-zone in mid-Scarborough appears to share this anomalously softer supply character, possibly reflecting a specific distribution routing through the Kennedy Road corridor that receives a blended supply with different hardness characteristics.

At 155 mg/L, Kennedy Park residents experience regular but moderate scale deposits — monthly kettle descaling is typical, but at a significantly lower rate than core Toronto neighbourhoods. The City of Toronto provides multilingual water quality information at toronto.ca/water. Health Canada lead service line precautionary guidance applies to the neighbourhood's post-war housing stock, and residents in pre-1955 bungalows and older apartment buildings should check the City's lead service line replacement programme.
