Understanding Burlington's water
Burlington gets Lake Ontario water from Halton Region's Burlington, Burloak and Oakville treatment plants. Halton's 2025 distribution average was 124 mg/L hardness (about 7.3 grains per gallon), with fluoride added at around 0.67 mg/L and sodium of 15 mg/L. Bridgeview in the far west end is supplied by Hamilton, and North Aldershot runs at about 125 mg/L.
| Supply | Hardness (mg/L) | Grains / gallon |
|---|---|---|
| Burlington (lake) | 124 | 7.3 |
| North Aldershot | 125 | 7.3 |
| Bridgeview (Hamilton supply) | 125 | 7.3 |

Why Burlington homes treat their water
Burlington's lake water is hard enough to scale kettles, shower glass and water heaters, and it's chlorinated, so most homes want both a softener and chlorine filtration.
