Consultation on Proposed Amendments to Pre-Start Health and Review Requirements for Factories

The Ministry of Labour, Training and Skills Development (MLTSD) is proposing to amend section 7 of the Industrial Establishments regulation (Regulation 851) under the Occupational Health and Safety Act (OHSA), which requires that a pre-start health and safety review (PSR) be carried out on certain machinery, protective elements, structures and processes in factories before they are put into service for the first time or if modifications are needed.

Between February 3 and April 30, 2020, the ministry held a consultation to get stakeholder feedback about the current pre-start health and safety review requirements and the current PSRs guideline. The feedback received indicated that while there is general support for PSRs and their role in proactively protecting worker health and safety, there was strong support for changes that would clarify and streamline the regulatory requirements.

Based on the feedback received during that consultation, the ministry is now proposing amendments to section 7 and the table to that section.

Amendments to Ontario Regulation 297/13 (Occupational Health and Safety Awareness and Training)

In Ontario, workers who must use certain fall protection equipment on construction projects are required to complete Working at Heights (WAH) training approved by the Chief Prevention Officer. As of January 1, 2021, Ontario Regulation 297/13 (Occupational Health and Safety Awareness and Training), made under the Occupational Health and Safety Act, will recognize fall protection training approved by WorkplaceNL in addition to Ontario’s Working at Heights training program.

There is an existing exemption from Working at Heights training requirements for automobile manufacturers and assemblers that directly employ workers at construction projects located at an automobile manufacturing or assembly plant operated by that employer. As of January 1, 2021, the exemption will be expanded to include a few additional workplaces that are directly owned and operated by an automobile manufacturer or assembler.

For more information, read the amending regulation Ontario Regulation 751/20 or the amended Occupational Health and Safety Awareness and Training regulation (Ontario Regulation 297/13).

Proposal to Modernize Regulatory Requirements for Part VII – Notices under the Occupational Health and Safety Act

All workplaces covered by the Occupational Health and Safety Act are required to provide notice and reports to the Ministry of Labour, Training and Skills Development and/or other specified workplace parties (such as the Joint Health and Safety Committee) of any fatalities, critical injuries, occupational illnesses and other prescribed incidents or occurrences at the workplace (Part VII – Notices: Sections 51 to 53.1, Occupational Health and Safety Act).

To assist employers in meeting their obligations under Part VII – Notices of the Occupational Health and Safety Act, the Ministry of Labour, Training and Skills Development is proposing to streamline the prescribed written reporting requirements into a single regulation that would apply to all workplaces covered under the Occupational Health and Safety Act.

Input Needed: Temporary Help Agencies

The ministry is seeking input on the potential creation of a temporary help agency registry to improve compliance with the Employment Standards Act, 2000 by temporary help agencies and their clients.

Proposal to Recognize Alternative Fall Protection Training

In Ontario, workers who are required to use certain fall protection equipment on construction projects must complete Working at Heights (WAH) training approved by the Chief Prevention Officer. These requirements are set out in the Occupational Health and Safety Awareness and Training Regulation (O. Reg. 297/13), made under the Occupational Health and Safety Act.

The Ministry of Labour, Training and Skills Development is proposing to amend O. Reg. 297/13 to allow for the recognition of Fall Protection training approved by WorkplaceNL as an acceptable alternative.

In addition, the Ministry is proposing to expand an existing exemption so that it applies to more workplaces owned and operated by an automobile manufacturer or assembler, thereby eliminating the need for these auto sector workplaces to have two separate training programs for some workers who are directly employed by them.

The proposed amendments would maintain a high level of worker health and safety, support labour mobility and eliminate duplicative training costs.

For more information on the proposal please visit the Government of Ontario’s Regulatory Registry.

Pre-Start Health and Safety Review Consultation

Section 7 of the Industrial Establishments regulation (Regulation 851) under the Occupational Health and Safety Act (OHSA) requires that a pre-start health and safety review be carried out on certain machinery, protective elements, structures and processes before they are put into service for the first time or if modifications are needed (see subsection 7(2)).  The section applies only to factories (as defined in the OHSA) and not other types of workplaces that are also defined as industrial establishments (offices, arenas, etc.).

The Ministry of Labour, Training and Skills Development is reviewing the current pre-start health and safety review requirements, also known as pre-start review (PSR) requirements, to ensure that they continue to reflect the realities of today’s workplaces. While maintaining existing worker health and safety protections, the review will consider whether:

  1. there are opportunities to streamline the existing requirements or reduce burden on business,
  2. the equipment and processes that trigger a PSR are appropriate, and
  3. there are ways to make the requirements clearer and easier to understand.

Amendments to the Industrial Establishments Regulation (Reg. 851)

The Industrial Establishments Regulation (Reg. 851) under the Occupational Health and Safety Act, sets out requirements in section 13 for where guardrails must be installed. Section 13 also states that the guardrail requirements do not apply to certain areas in the workplace, namely, loading docks, roofs that are accessed only for maintenance purposes, or pits used for work on an assembly line or for vehicle maintenance.

Section 13 of Reg. 851 was recently amended to add a new exemption for a conveyor or similar system that transports a vehicle or vehicle part and any raised platform used with the conveyor or similar system. The exemption is limited to situations in which a guardrail would obstruct the passage of the vehicle or vehicle part, prevent workers from performing work, or pose a hazard to a worker.

In situations where any of the exemptions to the guardrail requirements apply and there is no guardrail, an additional amendment now requires employers to develop and implement other measures and procedures to protect workers from the hazard of falling.

The amendments came into force on October 26, 2018. For more information on the amendments please visit:

  • the consolidated version of the Industrial Establishments Regulation, section 13.
  • the Source Law section of the e-Laws website for the amending regulation, O. Reg. 456/18
