TRCA's maps show this address is outside the areas that could flood from rivers in a major storm (TRCA plans for a storm like Hurricane Hazel in 1954) and outside lake shoreline hazards. Basement flooding from overloaded sewers can still happen anywhere in the city.

Lead in tap-water tests, postal area M5E0% of tests above Ontario's limitYour area · M5ENon Regulated Lead Sample · 6 tests, Sep 8, 2017 to Jun 29, 2026

In postal area M5E, 0 of 6 home tap-water samples (0%) tested above Ontario's limit for lead (10 micrograms per litre). That's too few samples to compare with the rest of the city. Health Canada recommends a stricter limit of 5 micrograms per litre: 0 samples here (0%) 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.

TRCA mapping is for screening, not site-specific decisions. Lead results are voluntary samples from homes in the postal area, not this address.
