05Risks and environment
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.
In postal area M4V, 3 of 114 home tap-water samples (2.6%) tested above Ontario's limit for lead (10 micrograms per litre). Across Toronto, 2.0% of samples did, so M4V is about the same as the city overall. Health Canada recommends a stricter limit of 5 micrograms per litre: 3 samples here (2.6%) 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.
Air Quality Health Index from Environment and Climate Change Canada's Toronto Downtown station, 1.8 km away, measured 12:00 PM EST Sunday 8 November 2026. Forecast high for the next 24 hours: 2 (low risk). The scale runs from 1 to 10+; 1 to 3 is low risk.
TRCA mapping is for screening, not site-specific decisions. Lead results are voluntary samples from homes in the postal area, not this address.
