PSR in Ontario: What a Pre-Start Health & Safety Review Means for Your Facility
If you’ve searched for “PSR Ontario” or “I need a Pre-Start Health & Safety Review”, you’re likely installing or modifying equipment or processes in a factory or industrial facility — and need to ensure compliance before operation.
A PSR is legally required under the Occupational Health and Safety Act (OHSA) when certain safety-critical changes occur in a workplace. A **licensed Professional Engineer in Ontario** must review the installation and provide a sealed PSR report confirming compliance and safety measures.
When Do You Need a PSR?
Under O. Reg. 851 Section 7, a PSR is required when a new process, apparatus, structure or protective element is to be constructed, added or installed (or if an existing apparatus, structure, protective element or process is to be modified), if any of these eight “triggers” are relevant, and the corresponding regulatory provisions apply:
- Flammable liquids are to be stored in quantities greater than 235 litres, or if they are to be dispensed at all
- New or modified protective elements are present (guards, safety devices, interlocks)
- New or relocated storage racking/shelving systems
- New or modified processes that include a risk of ignition or explosion
- New or modified dust collectors that involve a risk of ignition or explosion
- New or modified processes involving molten materials
- New or modified cranes, hoists, or lifting devices
- Hazardous chemical or biological agents are present and a ventilation system is used to protect workers
If any of these apply, you must complete a PSR before workers are exposed to the hazard.

- Description of equipment, process, or structure
