Federal rules cap lead in most consumer paints at 90 mg/kg, and homes built before 1960 carry the highest risk of older, leaded coatings on walls, trim and sills. If you’re planning renovation work in an older Ottawa property, don’t sand, torch or heat-strip painted surfaces until you’ve tested them or called a certified abatement contractor for an assessment.
TL;DR:
- Canada’s 90 mg/kg limit has applied to new consumer coatings since 2010, but it does not cover older paint already on Ottawa homes.
- Home test kits offer only a quick screen; lab chip analysis measures concentration, while certified XRF inspectors can detect lead through multiple paint layers.
- When removal is necessary, use chemical strippers in contained spaces or replace the painted component rather than use heat guns or open flames.
- Hire licensed abatement contractors for peeling paint, large renovation areas, or homes with children under six or pregnant occupants, and request clearance documentation afterward.
- Liquid paint and solvents go to Ottawa’s Trail Road or Navan Road facilities or participating Take It Back! stores; dry, empty cans may be recycled.

What federal rules say about lead in paint
The Surface Coating Materials Regulations (SOR/2016-193) set the legal ceiling for lead in most consumer paints sold in Canada at 90 mg/kg of total lead, measured on a dried paint sample. This limit has applied to new consumer surface coatings since 2010, which means paint manufactured and sold since then is formulated to stay under that threshold. Older paint already on the walls of an Ottawa home isn’t covered retroactively, so the regulation protects what you buy today, not what’s already on your trim.
The regulations also set out:
- Testing methods manufacturers must use to confirm a product meets the 90 mg/kg limit
- Labelling and warning requirements for any surface coating that falls outside the standard exemptions
- Scope limits that exclude certain specialty and industrial coatings from the consumer threshold
For a deeper look at how this rule plays out for homeowners across the country, our 90 mg/kg rule breakdown walks through the practical side of compliance.
Does your Ottawa home likely have lead paint?
Age is the single best predictor. Homes built before 1960 are highly likely to have lead-based paint somewhere in the structure, often under several newer coats. Homes from 1960 to 1990 may still carry lower lead concentrations, particularly on exterior trim, window frames and older baseboards. Anything built after 1990 is far less likely to be a concern, though base coats under later renovations are still worth checking in homes constructed before 1991, according to Health Canada’s chemical DIY guidance.
Once you suspect lead, you have three practical testing routes:
- Home test kits give a quick yes or no but are less reliable on multiple paint layers
- Lab paint-chip analysis offers a precise lead concentration from a physical sample
- XRF testing by a certified inspector reads lead levels through multiple layers without cutting into the wall
For anything beyond a quick screen, an accredited lab or a certified inspector recognized under Standards Council of Canada protocols gives you a result you can act on with confidence.
Safe renovation practices: what to avoid and what to use instead
Health Canada warns against dry sanding, heat guns and open-flame stripping on any surface that might contain lead paint, because all three methods release fine lead dust or fumes into the air you breathe. Intact lead paint in good condition, away from chewable surfaces like windowsills, is often the safest left alone rather than disturbed.
When work is necessary, safer methods include:
- Chemical strippers applied according to label directions, in a ventilated, contained area
- Encapsulation, which seals the surface rather than removing it, a faster and often more cost-effective option for sound paint
- Full component replacement, such as swapping an old window sash instead of stripping it in place
Pro Tip: Seal HVAC vents and return ducts before any work begins; lead dust travels through a home’s ductwork far faster than it travels through the air in a single room.
Basic containment, plastic sheeting, sealed doorways and a clear work zone, keeps dust from spreading, but it has limits. Simple sheeting alone rarely stops dust from reaching HVAC returns, which is one reason larger jobs call for negative air pressure and continuous HEPA filtration rather than homeowner-grade containment.
When to call a licensed abatement contractor
Some situations call for a professional rather than a weekend project. Watch for:
- Paint that’s chipping, flaking or peeling, especially on sills, door frames or stair rails
- Chew marks or visible wear on painted surfaces where young children spend time
- Any renovation that will disturb large areas of painted wall, trim or plaster
- A household with children under six or a pregnant occupant, where exposure risk carries more weight
A licensed contractor coordinates testing, sets up proper containment, performs HEPA-filtered cleanup, handles waste according to hazardous material rules and finishes with clearance testing to confirm the space is safe to re-occupy. When you request a quote, ask for an itemized breakdown covering testing, containment, labour, disposal and clearance reporting, and ask what the clearance report will document once the job wraps. For a side-by-side look at when abatement makes more sense than a standard renovation, see our guide to lead abatement versus renovation.
How to dispose of old paint and hazardous waste in Ottawa
Leftover paint counts as household hazardous waste in Ottawa, and it never belongs in your curbside trash or recycling bin. The City runs two permanent facilities, Trail Road and Navan Road, where residents can drop off leftover paint year round, and the Take It Back! retail program lets you return many paint products directly to participating stores.
- Dry, empty paint cans with the lid removed can often go out with regular metal recycling
- Liquid paint, solvents and stripping chemicals must go to an HHW facility or a Take It Back! retailer, never in the trash
- Use the City of Ottawa’s Waste Explorer tool to confirm current drop-off hours and accepted materials before you go
A step-by-step checklist for Ottawa renovation projects
- Check your home’s build year and flag any surface built before 1991 for a closer look
- Stop work immediately if you spot chipping, flaking or chalking paint on an older surface
- Order a lab test or book a certified inspector for an XRF reading before you touch the area
- Decide between encapsulation and full removal based on the paint’s condition and the test result
- Request itemized quotes from licensed abatement contractors, including containment and disposal costs
- Confirm the contractor’s containment plan, including HVAC sealing, before work starts
- Ask for a written clearance report once the work is complete, confirming the space is safe
- Arrange proper disposal of waste and leftover materials through Ottawa’s HHW program rather than regular trash
Environmental planning matters on the construction side too. Our partners at Prozone’s environmental considerations guide cover containment and site planning principles that apply well beyond lead work, useful background if you’re managing a larger renovation alongside abatement.
What we see go wrong on Ottawa renovation sites
The mistake we see most often is a homeowner sanding a painted sill or door frame without testing first, usually to save time or money. Poor containment is the second most common issue, plastic sheeting taped up loosely while a window unit runs nearby, pulling dust straight through the house. Skipping clearance testing after the fact leaves no record that the space is actually safe. We coordinate directly with local labs for sample analysis and with the City’s HHW facilities for proper disposal, which keeps a project compliant from first test to final cleanup.

FAQ
How to safely remove lead paint from wood?
The safest approach avoids dry sanding, heat guns and open-flame stripping, since all three release lead dust or fumes into the air. Chemical strippers used in a well-ventilated, contained space, or full replacement of the painted component, are safer options, and a certified contractor can confirm which method fits your situation.
How to get rid of old paint cans in Ottawa?
Empty, dry paint cans with the lid off can typically go out with regular metal recycling, while liquid paint and solvents must go to a City of Ottawa household hazardous waste facility at Trail Road or Navan Road, or to a Take It Back! retail partner. Never place liquid paint in curbside trash or recycling bins.
What year was lead paint banned in Canada?
Canada’s current limit of 90 mg/kg total lead in most consumer surface coatings has applied since 2010 under the Surface Coating Materials Regulations. Homes built before that point, especially before 1960, are more likely to have older, higher-lead paint still on their surfaces.
Is lead paint still toxic if painted over?
Intact lead paint that’s sealed under newer coats and in good condition is often considered lower risk and best left undisturbed, according to Health Canada. The hazard rises sharply once that paint starts chipping, flaking or gets disturbed by sanding, drilling or demolition, which is when testing or professional abatement becomes worth considering.
