How to use these sources
The references above are national and provincial starting points. None of them can tell you what is present in one specific house. They describe how construction is regulated, what published guidance exists, and which body holds records. Turning that into a fact about an address takes a record request or an inspection by someone qualified to make the finding, followed by a written record of the result.
A workable order is: note what you can observe, avoid disturbing anything suspected to contain a hazardous material, ask the authority or professional who can actually establish the fact, and keep the answer in writing. An era association is a reason to ask a question, not an answer to it, and a gap in the records is a research result rather than evidence of a defect.
What each kind of source can establish
- Federal guidance — published health and construction guidance, model codes, and testing methods. It does not describe any one property.
- Provincial authorities — the code in force in that jurisdiction, contractor licensing, and electrical, gas or boiler permit histories.
- Municipal building departments — the property file: permits, drawings, inspection outcomes and any open orders.
- Qualified professionals and laboratories — the condition of the building today, and confirmation of a material by sampling and analysis.
Documents worth gathering for any older home
- Municipal property file or permit search result for the address
- Provincial electrical, gas and boiler permit history
- Appliance make, model, serial number and service invoices
- Contractor invoices, warranties and any engineering reports
- Laboratory reports for any material that was sampled and tested
- A written list of records that were requested but not produced
Requirements and record-request procedures differ by province, territory and municipality. Confirm both with the authority that covers the property's address before relying on anything here.
