Imported Machinery PSR Requirements in Ontario (Regulation 851 Compliance Guide)

Imported Machinery PSR Requirements in Ontario (Regulation 851 Compliance Guide)
Imported machinery is one of the most misunderstood triggers for a Pre-Start Health & Safety Review (PSR) under Ontario Regulation 851 – Industrial Establishments.
Many manufacturers assume that CE marking, UL certification, or foreign engineering approval is sufficient. In Ontario, this is not the case. Equipment must comply with Ontario-specific regulations and may require a PSR before being placed into operation.

Regulation 851 PSR Trigger Determination
How Imported Machinery Triggers a PSR
A PSR may be required when imported equipment introduces any of the regulated hazard categories under Section 7.
This commonly includes:
- Machine safeguarding systems
- Combustible dust risks
- Flammable liquid processes
- Robotics and automated systems
- Lifting or material handling systems
Each of these must be evaluated under Regulation 851 Section 7 Table 1.
Why Foreign Certifications Are Not Enough
Many imported machines are designed to:
- CE (European standards)
- UL / ANSI (United States standards)
- ISO standards
While these may demonstrate general safety intent, they do not guarantee compliance with:
- Ontario Regulation 851
- OHSA requirements
- CSA standards (such as CSA Z432)
This is why imported equipment often requires additional engineering review before installation.
Common Compliance Issues with Imported Equipment
- Guarding systems not compliant with CSA Z432
- Unsafe access to hazardous motion
- Electrical systems not aligned with Canadian requirements
- Inadequate safety control systems
- Missing or incomplete engineering documentation
These deficiencies frequently result in delays, redesign, costly retrofits, or enforcement issues.
Engineering Review for Imported Machinery PSR
A PSR for imported machinery typically includes:
- Review of existing drawings and documentation
- Hazard identification and risk analysis
- Verification of safeguarding systems
- Assessment of compliance with Ontario standards
- Identification of deficiencies and corrective actions
- Final engineering approval (P.Eng. sign-off)
Ontario Sign & Seal Requirements
In many cases, imported machinery must be reviewed and approved by a Professional Engineer licensed in Ontario.

FAQ: Imported Machinery PSR Ontario
Does imported machinery require a PSR in Ontario?
It may. If the equipment introduces a regulated hazard under Section 7, a PSR is required before operation.
Is CE certification accepted in Ontario?
No. CE marking does not replace Ontario regulatory compliance requirements.
Do I need a P.Eng. for imported equipment approval?
Yes. A Professional Engineer licensed in Ontario must review and approve applicable systems.
Can HITE Engineering help before equipment arrives in Canada?
Yes. Early review helps prevent costly redesign and compliance delays.
