Yes, when the labour and materials are expected to cost more than $50,000. Before construction begins, the constructor, the party in charge of health and safety on the project, files a Notice of Project with Ontario's Ministry of Labour and keeps a signed copy posted at the site. Every constructor and employer also completes a Form 1000 registration. JDT Construction plans commercial jobs in Hamilton with these filings first.

## When is it required?

Before construction begins on any project that meets section 6 of the Regulation for Construction Projects (O. Reg. 213/91). Ontario's example: “a notice of project is required if the total cost of labour and materials for the project is expected to exceed” $50,000, or $250,000 for a project confined to a car factory [(Government of Ontario, File a work notice, read November 5, 2026)](https://www.ontario.ca/page/file-work-notice). Section 6 has other conditions too, so the full list is worth reading for any project.

## Who is the constructor?

The Occupational Health and Safety Act: a constructor “means a person who undertakes a project for an owner and includes an owner who undertakes all or part of a project by himself or by more than one employer” [(Occupational Health and Safety Act, s. 1 (1), read November 5, 2026)](https://www.ontario.ca/laws/statute/90o01). So a general contractor running the whole job is usually the constructor; an owner who hires several trades directly can become one.

## Which notices and forms come with a project?

**Ontario work notices and forms for a construction project**

| Notice or form | When |
| --- | --- |
| Notice of Project | Before construction begins on a project over $50,000 in labour and materials, or meeting other s. 6 conditions |
| Form 1000 registration | Every constructor and employer, before beginning work; kept at the project, not sent in |
| Notice of trench work | A trench more than 1.2 m deep that a worker may enter |
| Notice of asbestos removal | Before a Type 3, and certain Type 2, asbestos removal operations |
| Suspended work platform | At least 48 hours before first use |

Each row is from Ontario's page [(Government of Ontario, File a work notice, read November 5, 2026)](https://www.ontario.ca/page/file-work-notice), which also says a signed copy of the Notice of Project “must be posted in a conspicuous place at the project or be available at the project for review by an inspector.” Filing is online with an Ontario.ca login, or on paper to the regional office.

## What else comes before the work starts?

On a renovation, the owner's list of designated substances such as asbestos ([asbestos and designated substances](https://www.jdtconstruction.ca/guides/designated-substances/)). On a major commercial build, site plan approval and stamped drawings before the permit ([site plan approval](https://www.jdtconstruction.ca/guides/site-plan/)). The full order is on the [commercial page](https://www.jdtconstruction.ca/builds/commercial/), and JDT Construction Inc. plans a job in that order.
