Ontario Site Registration
Ontario Form 1000 — Registration of Constructors and Employers
Before anyone starts work on a construction project in Ontario,
every constructor and every employer on that job has to complete an
approved registration and keep a signed copy at the project. That
registration is Form 1000.
It is required by Ontario Regulation 213/91, section 5,
made under the Occupational Health and Safety Act. The Ministry
publishes the official version as form 016-1000E.
Unlike a Notice of Project, there is no dollar threshold — if you are
a constructor or an employer engaged in construction on the project,
it applies to you.
What the registration asks for
Gather these before you fill anything in — it is the same set the
Ministry form asks for.
- Legal business name, and operating name if different
- Whether you are the constructor or an employer on the project
- Business address and contact
- WSIB account number
- Trade or type of work
- Project address and the date work begins there
- Emergency contact and number
- Signature, name and title
Who has to complete one
The regulation is broad on purpose. It is not only the constructor
running the site.
- The constructor for the project
- Every employer engaged in construction on that project
- Each one registers separately, before starting work
Where the copy has to live
A copy of the completed form is kept at the project while that
employer is working there. Not at head office, not in the truck
somewhere — at the project.
That is the part most sites get caught on, because the form gets
filled in once and then goes missing by the time anyone asks for it.
Form 1000 vs Notice of Project
They get confused constantly. Both can apply to the same job.
- Form 1000 — a registration each constructor and employer completes, no dollar threshold, kept on site
- Notice of Project — filed with the Ministry once labour and materials exceed $50,000, or for certain high-hazard work
Frequently asked questions
What is a Form 1000?
Form 1000 is the Registration of Constructors and Employers Engaged in Construction — the Ministry of Labour registration required under Ontario Regulation 213/91, section 5. Every constructor and every employer engaged in construction has to complete it before beginning work at a project, and keep a signed copy at the project while working there. The Ministry publishes it as form 016-1000E.
Is Form 1000 the same as a Notice of Project?
No, and they are easy to confuse. A Notice of Project is filed with the Ministry when a project crosses the cost threshold or involves certain high-hazard work. Form 1000 is a registration that each constructor and each employer completes for themselves, regardless of project value, and keeps on site. A single project can require both.
Does Form 1000 have to be posted at the project?
The regulation requires that a copy of the completed form is kept at the project while that employer is working there. In practice most sites keep it with the rest of the site documentation so it can be produced when an inspector asks.
Where do I get a blank or fillable Form 1000?
The official blank form is published by the Ontario government as 016-1000E and should be obtained from the Ministry. The worksheet on this page is for gathering the same details in advance and keeping your completed copy on file — it is preparation and record-keeping, not a substitute for the Ministry form.
Why does Form 1000 ask for a WSIB number if it is a Ministry of Labour form?
The registration asks for your WSIB account number among the business details, which is why it is often described as a WSIB requirement. The obligation itself comes from the construction regulation under the Occupational Health and Safety Act, not from WSIB.
Next Step
Fill it in once, and still have it when the inspector asks
The worksheet collects everything the registration asks for. Blue Crane
keeps the completed copy against the job it belongs to, so the copy the
regulation says has to be at the project actually is.
