You cannot reliably identify asbestos by sight, and a home’s age only tells you the risk. Homes built or renovated before 1990 may contain asbestos. If a repair or renovation could disturb a suspect material, stop work, don’t touch, sweep or vacuum it, and arrange professional sampling and lab analysis first. Intact, undisturbed material often poses little immediate risk.
TL;DR:
- Older Ottawa homes may contain asbestos in vermiculite, ceilings, joint compound, tiles, pipe insulation, cement, plaster, siding, or roofing; appearance and age cannot confirm it.
- Before renovation, stop work and avoid cleaning or moving suspect material; a qualified professional should collect samples for laboratory testing and record each location.
- Keep vermiculite insulation undisturbed, restrict attic access, and keep children out; call a qualified professional before storage or renovation work.
- If testing finds asbestos in material your project will disturb, hire a qualified contractor; work classification determines required controls and the contractor’s price.
- Ottawa treats asbestos as special waste, not regular garbage; household depots accept household quantities only, so ask contractors for disposal receipts.

Where asbestos hides in older Ottawa homes
Before 1990, asbestos was mainly used to insulate and fireproof buildings, and its manufacture, import, sale and use are now prohibited in Canada. Older Ottawa houses can still hold it in several places:
- Vermiculite attic insulation
- Popcorn or stipple ceilings and joint compound
- Floor and ceiling tiles
- Cement and plaster
- Insulation around pipes, hot water tanks and furnaces
- Siding and roofing products
Age is a risk indicator, not a diagnosis. Health Canada says appearance and date of construction cannot confirm or rule out asbestos, so only lab testing settles the question.
Vermiculite attic insulation is a special case. Don’t rake it, vacuum it, bag it or use the attic for storage. Keep children out, and call a qualified professional before any attic work. Health Canada’s vermiculite guidance says that if the material is intact and nothing will disturb it, the usual response is to leave it alone and restrict access.
A safe testing workflow: stop, sample, send to the lab, act
Health Canada’s guidance for indoor air quality professionals says materials likely to be disturbed should be tested in a laboratory. Don’t sample friable, crumbly material yourself. Here is the order we follow with homeowners:
- Stop any intrusive work and keep people away from the area.
- Leave the material alone: no cleaning, moving, sanding or vacuuming.
- Have a qualified professional collect representative samples.
- Submit the samples to a laboratory.
- Get written results that state what was found and where.
- Use those results to choose containment, repair, isolation or removal before work resumes.
The results shape the decision. Asbestos in a wall you will open needs a different plan than asbestos in a sealed, untouched area, where managing or isolating it may be enough. Testing before removing keeps you from paying to tear out material that could have stayed put. If you are planning a renovation, our guide to how asbestos affects renovation plans shows how to build survey results into your schedule.
Pro Tip: Photograph the material from several angles, note its location and condition, and write down the date. Contractors can estimate faster with this record, and it helps with any insurance or permit questions.
When to hire a licensed abatement contractor
If lab results show asbestos in a material your project will disturb, hire a qualified asbestos contractor. Don’t attempt DIY removal. Ontario guidance says an owner should determine whether designated substances such as asbestos are present before tendering work. Work is classified as Type 1, 2 or 3, and that classification drives the controls and the price, so a contractor needs your full scope before quoting. Confirm how these rules apply to your project and contractor.
Asbestos repair or removal should be handled by qualified professionals using appropriate procedures. Ask the contractor to explain the work plan and what documentation they will provide before anyone returns to the area. Our guide to safe asbestos renovation in Canada walks through the test, contain and clear sequence in more detail.
Ask every contractor for details.
- A written scope of work
- A containment plan
- A disposal plan with receipts
- A post-abatement air test report
- Any required permits
A renovation contractor checklist can also help you prepare questions. Our Ottawa asbestos removal cost guide gives you budget context before you call.
What to do in the first hour if material is disturbed
If you’ve already broken into something suspect, act calmly and quickly:
- Stop work, clear the area, close the doors and restrict access.
- Don’t sweep, vacuum or try to clean up the dust.
- Keep everyone out, especially children, and photograph the scene.
- Talk to a physician if you think you were exposed.
- Call a qualified testing or abatement professional to sample and secure the area.
Health Canada notes that a single exposure does not mean disease will follow, but repeated or substantial airborne exposure is preventable and should be taken seriously. Our first-hour checklist for disturbed asbestos covers each step in more detail.
How Ottawa handles asbestos disposal
The City of Ottawa treats asbestos as a special waste. Ottawa’s solid waste by-law lists asbestos among the special wastes the Trail Road Landfill accepts only with special handling, under a per-tonne tipping fee with a minimum charge. That is why you can’t toss it in the regular garbage.
- Household hazardous waste depots take household quantities only, and staff make the final call on what they accept.
- Renovation and demolition waste is not collected with regular garbage. For large or questionable items, call 3-1-1.
- Contractors normally manage disposal, so ask for disposal receipts in your quote.
Fees and rules change, so confirm current details with the City or your contractor before scheduling removal. Our Ottawa asbestos disposal guide explains owner responsibilities under Ontario regulations.
Why test first beats tear out first
Most of the worry we hear comes from the same few places: an old attic, a bungalow with a popcorn ceiling, mid-century floor tiles. The instinct is to rip it all out. A measured approach usually costs less and protects your family better. Testing tells you what you actually have, so you remove what a renovation will disturb and leave stable material alone. It also lines up the practical pieces early: lab turnaround, City disposal requirements and the paperwork a licensed professional handles for you.

FAQ
What year did they stop using asbestos in drywall?
There is no single cut-off year you can rely on. Health Canada says homes built or renovated before 1990 may contain asbestos, and joint compound and plaster are among the materials it names. Only a lab test confirms what your walls contain.
How do I test for asbestos in Ottawa?
Stop disturbing the material and have a qualified professional collect representative samples. They send the samples to an accredited laboratory and give you written results with locations. Don’t sample crumbly material yourself.
What was asbestos used for?
Before 1990 it was mainly used to insulate against cold and noise and for fireproofing. Products that may still contain it include cement, plaster, building insulation, siding, floor and ceiling tiles, roofing products and pipe insulation, according to Health Canada.
Is asbestos banned in Canada?
Yes. The manufacture, import, sale and use of products containing asbestos are prohibited in Canada. Asbestos installed in older homes before the ban can remain, which is why testing still matters.
