Lead paint in Ontario homes is a real issue that requires informed management during renovation. Here is a complete 2026 guide.
Which Homes Are Affected
Canada banned lead in residential paint in 1976. Pre-1976 homes very likely contain lead paint. 1976-1990 homes may have residual lead paint in some locations. Pre-war housing in Toronto, Hamilton, Ottawa, and other established neighbourhoods is most commonly affected.
Health Risks
Lead dust from sanding, scraping, or demolishing lead paint is the primary exposure route. Particularly dangerous for children under 6 and pregnant women. Lead paint in good condition and undisturbed poses low immediate risk.
Testing Options
Swab test kits (hardware stores): $10-$30, accessible but less reliable. XRF analyzer (professional): most accurate, non-destructive, $150-$300/visit. Lab analysis of scraped samples: $50-$150/sample. Test before any sanding, scraping, or demolition in pre-1976 homes.
Safe Renovation Practices
Wet-scraping before disturbing paint minimises dust. HEPA vacuum only — never dry sweep. P100 respirator, disposable coveralls, gloves. Contain and dispose of lead-contaminated materials as hazardous waste at Ontario designated facilities.
No Ontario-Specific Regulation
Unlike US EPA RRP, there is no Ontario regulation mandating lead-safe practices for renovation contractors. However, duty of care under OHSA applies. Homeowners and contractors should follow lead-safe work practices regardless.
