Water hardness in Lakeshore
Lakeshore, Ontario tap water is moderately hard, drawn from lake st. clair (belle river water treatment plant). Here is what it means at home, and the source.
What this means at home
Some kettle and showerhead scale over time, but most homes get by without a softener.
The Belle River plant treats surface water from Lake St. Clair. Hardness is reported as total hardness in mg/L as CaCO3.
You likely do not need a softener. A quick test kit confirms it for your own tap.

The number, in real terms
At 89.90 to 214.80 mg/L as CaCO3 (average 122.62) mg/L (5.3 to 12.6 grains per gallon), a four-person Lakeshore household puts only about 2,158 grains of hardness a day through its plumbing (industry sizing convention: about 300 US gallons a day). That is a light enough load that most homes skip the softener and just descale the kettle now and then.
Scale ceiling: every 1,000 litres heated can leave at most 123 grams of scale, because that is the total mineral carried at 89.90 to 214.80 mg/L as CaCO3 (average 122.62) mg/L. Real kettles and water heaters precipitate a fraction of that, but the ceiling scales with the number: Lakeshore's moderately hard water leaves little behind.
How this is calculated: grains per gallon = mg/L divided by 17.1; daily grain load = gpg x 300 US gallons (the softener trade sizes in US gallons, four-person household); regeneration interval = 32,000 grains divided by the daily load; scale ceiling = mg/L carried per 1,000 L. The input figure is Municipality of Lakeshore - 2025 Belle River Drinking Water System Annual Report's own published number, checked 2026-07-03. Full method on the methodology page.
