Lead is a naturally occurring, bluish-grey material.
Sources of lead
Lead is found in:
- Paint in homes built before 1978. Chipping, peeling or sanding paint can release lead into the air, household dust and soil.
- Dust inside homes. Dust can contain lead, especially in older homes that have lead-based paint. When you open and close windows or doors with lead paint, lead dust is created. Babies and young children often put their hands into their mouths after touching surfaces with dust such as floors.
- Some soils. Use of lead in products such as gasoline, paint and pesticides in the past contributes to the amount of lead found in soil. Lead does not break down over time, and is often found in areas close to where it was used in the past. Soil can be a source of lead exposure for children when they play outside.
- Drinking water in most North American cities because lead pipes were used in homes built before the 1960s and lead-containing soldering joints were used until the late 1980s. Lead can get into drinking water from valve parts or gaskets, older water service lines and indoor plumbing.
- Food or drinks stored in ceramic dishes, pottery or crystal glassware made outside Canada.
- Some toys and children's jewelry made outside Canada.
- Older PVC mini blinds.
- Clothes and shoes of people who work in lead-related industries, such as painters, automobile repairers, battery makers, stained glass makers and construction workers.

Protecting your family from lead
Here are some things you can do to reduce your family’s exposure to lead:
- If you live in a home built before 1978, clean up any peeling or chipping paint and make sure that your children do not play with or eat any paint chips.
- If you think your window or door frames have lead based paint, wipe them down with a wet cloth often, especially if they are opened and closed regularly.
- Check your home’s plumbing and the pipe that connects your house to the city water main for lead.
- If you are not sure if you have lead water service pipes, call 905- 546-4426 and request to have a Check Size and Type Inspection.
- Learn about how to reduce lead in tap water and how to replace your lead service pipes
