Many small trades, contractors, and owner-operators believe that a Notice of Project (NOP) is only required for massive multi-million dollar commercial builds or public infrastructure developments. This is a dangerous, incredibly expensive misunderstanding of Ontario site safety regulations.
Under the Ontario Occupational Health and Safety Act (OHSA) and O. Reg. 213/91 (Construction Projects), the Ministry of Labour, Immigration, Training and Skills Development (MLITSD) enforces strict, hard financial triggers that dictate exactly when an NOP must be filed.
The Strict $50,000 Threshold Mandate
By law, a constructor must submit an official Notice of Project to the Ministry before any work begins if the total expected cost of labor and materials for the construction project exceeds **$50,000**.
Think about modern material and labor costs. A simple commercial fit-out, a small structural roofing job, or an industrial mechanical equipment swap hits that $50,000 baseline almost instantly. If your total project cost crosses that number, there is zero legal wiggle room—filing is completely mandatory.
Important Threshold Exception: If the construction project takes place within an active automotive or manufacturing facility, the mandatory NOP filing threshold shifts to a project value exceeding $250,000.
The Physical Posting Trap: Visible and On-Site
Filing the form online from your home office or truck cab handles only half the legal battle. The law dictates that a printed, completed copy of the signed Notice of Project must be **physibly and clearly posted on the construction site** for the entire duration of the work.
When a Ministry inspector walks onto your job site for a surprise spot check, they don't want to wait for you to log into a portal on your laptop. They expect to see two specific documents prominently displayed on the site wall immediately:
- The Official Notice of Project (NOP): Complete with the active project timeline, emergency contact numbers, and specific engineering parameters.
- Form 1000 (Site Registration Profile): The mandatory registration profile identifying the legal constructor and every active employer engaged on the project.
If the inspector conducts an audit and these forms are missing, outdated, or sitting unprinted in an email inbox, they don't give out soft warnings. Under current enforcement rules, missing on-site postings give inspectors the authority to levy **Administrative Monetary Penalties (AMPs)** and issue immediate on-the-spot field fines to the project supervisor.
