Lead Paint & Drinking Water Testing
Lead persists in Canadian buildings two ways: paint applied before 1990 (heavily before 1960) and drinking water passing through lead service lines and old solder. Renovation of pre-1990 housing triggers worker-safety duties around lead paint, and Health Canada’s tightened water guideline of 5 µg/L has put thousands of buildings — including schools and daycares under mandatory testing programs — over the line.
Paint: the renovation trigger
Sanding, demolition and window replacement in older housing disturbs lead paint, and occupational health law requires identification and controls before workers create that dust — the same legal structure as asbestos. XRF surveys or lab-analyzed chips map where lead paint exists so the contractor works to the right precautions and the family is not dusted with it.
Water: lines and fixtures
Homes built before roughly 1960 may retain full or partial lead service lines; buildings into the late 1980s used lead solder. Testing follows a stagnation-and-flush protocol at the tap; results distinguish service-line lead from fixture lead, which determines the fix — municipal/private line replacement versus point-of-use filtration certified for lead. Many cities run replacement programs and cost-share the private side; we navigate those programs for owners.
Landlords, daycares and schools
Several provinces mandate lead testing in schools and licensed child care, and landlords of older buildings face growing expectations to know their service-line status — disclosure questions are already appearing in transactions.
How the process works
- Tell us the building age and whether the concern is paint, water or both.
- Sampling is completed — XRF/chips for paint, protocol tap samples for water.
- Accredited lab results identify the sources.
- Fixes are arranged: safe-work practices, line replacement, certified filtration.
- Follow-up sampling documents the resolved condition.

Frequently asked questions
Is lead paint dangerous if I leave it alone?
Intact lead paint under sound layers is a managed risk; friction surfaces (windows, doors) and any disturbance are the exposure routes. Know where it is before renovating — that is the whole game.
How do I know if I have a lead service line?
Scratch-test the pipe at the meter (lead is dull grey, soft, non-magnetic), check municipal records — many cities publish lookup tools — or have us verify. Partial private-side lines survive even where cities replaced their side.
What water result requires action?
Health Canada’s guideline is 5 µg/L, among the world’s strictest. Above it, fix the source; certified filters bridge the gap immediately while line replacement is arranged.
Does boiling water remove lead?
No — boiling concentrates it. Use cold water for consumption, flush after stagnation, and rely on certified filtration or line replacement for a real fix.
