Port Moody buys treated water from Metro Vancouver. The 2025 report gives 20.5 mg/L as CaCO3 for the Capilano source and 20.2 mg/L for the Seymour source. The city's own report prints no hardness and does not state the split between sources, so these are regional figures. The water is very soft and scale is rare.
Health Canada: hardness above 200 mg/L is considered poor but tolerable; above 500 mg/L unacceptable.
