Ontario Regulation 278/05 puts the responsibility on whoever is doing the renovation, demolition, repair, or maintenance work to know what is in the building first. A Designated Substance Survey is how that requirement gets satisfied, and it protects you, your contractor, and anyone who works in the space afterward.
We write every survey report the same way, whether it ends up with your contractor, your insurer, or the permit office, so it holds up wherever it needs to go.
We walk the entire scope of the project, not just the one room you're worried about.
Our surveys satisfy Ontario Regulation 278/05's requirement before renovation, demolition, repair, or maintenance work.
Reports are written to be usable by your contractor, permit office, or insurer, not just for your own reference.
We confirm what work is planned and which areas and materials the survey needs to cover.
We inspect and sample every suspect material across the defined scope.
Samples are analyzed at an accredited lab.
You receive a written Designated Substance Survey report to share with your contractor or permit office.
We size the survey to the work you are planning, not the whole building by default.
Every survey satisfies Ontario Regulation 278/05's documentation requirement.
Reports are written so your contractor can plan the work safely.
If something is found, you get a clear recommendation, not just a list of problems.
Every quote depends on the property size and how much of it the planned work will affect.

Satisfies Ontario Regulation 278/05 before work begins
Both. Ontario Regulation 278/05 requires a designated substance assessment before renovation, demolition, repair, or maintenance work on a building that may contain asbestos, particularly buildings built before 1990.
A quick inspection targets one or two suspect materials you've already identified. A full Designated Substance Survey covers the whole scope of a planned renovation or demolition and is what satisfies the regulatory requirement before that work begins.
Both. Your contractor needs it to plan the work safely and legally, and you may need it for permits or insurance, so we write every report to be usable by all three.
