Asbestos Testing Services in Ottawa
When Was Asbestos Used in Canada?
This material was used in many construction products until late 1985. Asbestos fibers may become a risk during any type of home renovation or construction activity. The Ontario Ministry of Labour, Ontario Regulation 278-05 governs the asbestos abatement conditions that regulate its testing, removal, and management.
What is Asbestos Found in?
Asbestos-containing materials may be found in:
- Stipple ceilings
- Plaster or mud joint compound
- Cementitious parging – cement or plaster of Paris
- Stucco, caulking, pebble-textured exterior finish
- Pipe wrap, insulation, thermal paper
- Roof bitumen and fireproofing
- Adhesives, glues, mastics
- Floor and ceiling tiles
- Old boilers, water tanks, and radiators
The homeowner or building manager is responsible to determine what designated substances are in their home prior to construction or renovation for risks of exposure to workers and family.
Commercial buildings, rentals, and retail businesses must have testing and an asbestos management plan to comply with the government’s asbestos regulations.
Three common older home designated substances:
- Lead paint and solder, piping, and switches
- Asbestos in construction materials
- Silica in plaster, wallboard, cement, parging, and grout

Designated Substance Surveys
Before purchasing, renovating or demolishing a property, it is important to understand whether hazardous materials may be present. IAQ Ottawa provides Designated Substance Surveys for individual rooms, defined project areas or entire buildings.
Under Ontario’s Occupational Health and Safety Act, project owners must determine whether designated substances are present before work begins and provide that information to constructors and contractors. Ontario Regulation 278/05 also establishes requirements for managing asbestos during construction, renovation, repair and demolition work.
Our surveys can assess for designated substances such as lead, asbestos, silica, mercury and PCBs, helping property owners and project teams understand potential hazards and plan their work appropriately.
IAQ Ottawa inspector Shawn Rankin brings 35 years of construction management experience and was recognized by CMHC awards as a “Healthy Home Builder” and “Healthy Home Renovator” in 1999.
Why Use an Independent Asbestos Testing Company?
An independent asbestos testing company focuses on identifying and assessing suspected asbestos-containing materials without also selling removal services. This separation helps reduce potential conflicts of interest and gives property owners a more objective understanding of what was found, where it is located and what action may be required.
Indoor Air Quality Ottawa provides professional asbestos sampling and clear recommendations based on the inspection and laboratory results. If asbestos is confirmed, the report can help you understand whether the material may remain safely in place, requires ongoing management or should be addressed by a qualified asbestos abatement contractor before renovation or demolition work begins.

Asbestos Testing FAQs
Finding asbestos does not always mean that every affected material must be removed immediately. The next step depends on the material’s condition, location and whether the planned work will disturb it. Materials in good condition may sometimes be managed in place, while materials affected by renovation or demolition may require professional removal or other controls before work proceeds. Do not disturb or attempt to remove confirmed asbestos-containing material yourself.
Turnaround times depend on the number of samples collected, the laboratory’s processing schedule and whether standard or expedited analysis is requested. Your inspector should provide an estimated timeline after confirming the scope of the assessment. Renovation or demolition work should not begin in the affected area until the suspected materials have been assessed and the appropriate precautions are understood.
A qualified inspector first identifies materials that may contain asbestos and groups materials that are similar in appearance and composition. Representative bulk samples are then carefully collected from the areas that may be affected by the planned work and submitted to a laboratory for analysis. Ontario regulations establish minimum sampling requirements based on the material type and the size of the area being assessed.
A Designated Substance Survey identifies regulated hazardous substances that may be present within a building or project area before construction, renovation or demolition begins. In Ontario, designated substances include asbestos, lead, mercury, silica and several other regulated substances. The survey documents where suspected substances are located and helps contractors plan the work using appropriate health and safety controls.
Asbestos may be present in older floor and ceiling tiles, drywall joint compound, plaster, insulation, textured coatings, roofing materials, cement products, pipe and boiler insulation, siding, adhesives and vinyl flooring. You cannot confirm whether a material contains asbestos through appearance alone. Suspected materials should be professionally assessed and tested before they are disturbed.
You should arrange asbestos testing before renovating, demolishing or disturbing materials that may contain asbestos, particularly in homes and buildings constructed before 1990. Testing helps identify potential asbestos-containing materials before they are cut, drilled, sanded or removed. In Ontario, project owners must determine whether designated substances are present and provide that information to contractors before work begins.
