New Heat Stress Regulation Under the Occupational Health and Safety Act

Regulation Number(s):
Instrument Type:
Bill or Act:
Occupational Health and Safety Act
Summary of Proposal:
Heat stress is a significant cause of occupational illnesses that may lead to death. Heat-related illnesses affect all workers. Due to changes in our climate, extreme heat events are a growing health risk to workers in Ontario. MLITSD is now proposing to introduce a stand-alone heat stress regulation under the Occupational Health and Safety Act (OHSA) with specific requirements that would apply to all workplaces to which the OHSA applies.
Analysis of Regulatory Impact:
MLITSD is conducting a Regulatory Impact Analysis (RIA) of these proposed amendments. A RIA is a process of identifying and assessing the potential benefits and costs of proposed regulations. As part of this consultation, MLITSD is seeking your comments and feedback pertaining to the anticipated costs and benefits of implementing these proposed amendments.
