In postal area M5N, 2 of 152 home tap-water samples (1.3%) tested above Ontario's limit for lead (10 micrograms per litre). Across Toronto, 2.0% of samples did, so M5N is lower than the city overall. Health Canada recommends a stricter limit of 5 micrograms per litre: 5 samples here (3.3%) were above it. These are voluntary tests, mostly from older homes, so they don't tell you about this house. Lead comes from old pipes and plumbing, not the City's treatment plants. If your home was built before the mid-1950s, you can get a free test kit by calling 311.
