Asbestos Removal & Testing in Toronto

When Asbestos Testing Is Needed

Asbestos testing is required before any renovation or demolition work in buildings constructed before 1990. Under Ontario Regulation 278/05, property owners must identify and properly handle asbestos-containing materials before disturbing them. This regulation protects workers, occupants, and the public from asbestos exposure during construction activities.

Testing is also recommended during real estate transactions involving older properties, when materials show visible damage or deterioration, or before purchasing a home built before 1990. Professional asbestos testing involves collecting samples of suspect materials and sending them to an accredited laboratory for analysis. Results typically return within a few business days and identify whether asbestos is present and in what concentration.

Where Asbestos Is Found

In Toronto and GTA homes built before 1990, asbestos is commonly found in:

• Vermiculite/Zonolite Insulation: Gray, pebble-like attic insulation that may contain asbestos fibres. Zonolite brand vermiculite often contained asbestos from contaminated mines.
• Vinyl Floor Tiles & Adhesives: 9x9-inch and 12x12-inch vinyl floor tiles and the black mastic adhesive underneath often contain asbestos.
• Ceiling Tiles: Drop ceiling tiles and sprayed-on acoustic ceiling texture (popcorn ceilings) applied before 1980.
• Pipe Wrapping: White or gray insulation wrapped around pipes and ductwork in basements and mechanical rooms.
• Drywall Compound: Joint compound and plaster used in buildings constructed or renovated before 1980.
• Roofing Materials: Asbestos cement shingles and roofing felt on older homes.
• Cement Board Siding: Exterior siding panels on homes built between 1940 and 1980.

Our Asbestos Testing Process

Our certified technicians collect samples of suspected asbestos-containing materials using proper safety protocols. Samples are packaged and sent to an accredited laboratory for polarized light microscopy (PLM) analysis, which identifies asbestos fibres and determines the percentage of asbestos present. Most results are available within 3 to 5 business days.

If asbestos is confirmed in materials that will be disturbed by your renovation or demolition work, we develop a safe abatement plan that complies with Ontario Regulation 278/05. The plan includes containment specifications, removal procedures, waste disposal methods, and clearance testing requirements.

Safe Asbestos Removal Process

Our licensed asbestos abatement process follows strict protocols:

1. Containment Setup: We seal off the work area with polyethylene sheeting and create a decontamination unit with multiple chambers for worker entry and exit.
2. Negative Air Pressure: HEPA-filtered negative air machines maintain lower air pressure inside the containment area, preventing asbestos fibres from escaping to other areas.
3. Careful Removal: Workers wearing full respirators and protective suits carefully remove asbestos materials using wet methods to minimize fibre release.
4. Air Monitoring: We conduct air monitoring throughout the abatement process to verify containment effectiveness and worker safety.
5. Licensed Disposal: All asbestos waste is double-bagged, labeled, and transported to provincially licensed disposal facilities that accept asbestos-containing materials.
6. Clearance Testing: After removal, an independent third party conducts air sampling to verify the area is safe for reoccupancy before containment is removed.

Ontario Asbestos Regulations

Ontario Regulation 278/05 under the Occupational Health and Safety Act governs asbestos work in the province. The regulation classifies asbestos work into three types based on the quantity and condition of materials being disturbed. Type 1 work involves small amounts of non-friable asbestos and has minimal requirements. Type 2 work involves larger quantities or friable materials and requires written procedures and worker training.

Type 3 work includes major asbestos abatement projects and requires licensed contractors, written abatement plans, worker certification, and air monitoring. Most residential asbestos removal projects in Toronto fall under Type 2 or Type 3 requirements. Our team is fully trained and licensed to perform all types of asbestos work in compliance with Ontario regulations.

Cost Factors

Asbestos removal costs in Toronto typically range from $2,000 to $10,000 or more depending on several factors. The type of asbestos material affects cost because friable materials require more stringent containment. The quantity of material to be removed determines project size and duration. Accessibility matters because difficult-to-reach areas require more time and effort. Location within the building affects containment requirements and disposal logistics.

While asbestos abatement costs may seem high, cutting corners on asbestos work is dangerous and illegal. Improper asbestos removal creates serious health risks, may violate Ontario regulations and result in fines, can contaminate your entire property requiring far more expensive cleanup, and will likely be discovered during home inspections if you sell your property. Professional, licensed asbestos removal protects your health, complies with regulations, and provides documentation for future property transactions.
