Beaconsfield is served from the Pointe-Claire plant, run by the Ville de Montréal. The 2025 plant summary prints calcium (18.17 mg/L average) and magnesium (3.32 mg/L) but no hardness row, so the figure is computed from those two: about 59 mg/L as CaCO3. It is a plant-level value shared with nearby networks. Scale builds up slowly at this level.
Health Canada: hardness above 200 mg/L is considered poor but tolerable; above 500 mg/L unacceptable.

- Soap lathers easily; water does not dry skin or hair.
- Dishwasher: salt setting at minimum or off.
- No softener needed; a jug filter only changes taste.
How much salt will you use for softening?
No. Water this soft does not need softening.
Descale a coffee machine or kettle about every 6 months (typical manufacturer guidance for this hardness).
