New funding announced for worker safety in mining and forestry
In what was described as a strategic, provincewide collaboration, the WSIB has partnered with Workplace Safety North (WSN) and the Institute for Work and Health (IWH) to lead a proactive campaign aimed at enhancing hygiene monitoring practices and reducing exposure to harmful workplace hazards. The initiative, spearheaded by WSN, is to focus on high-risk sectors such as mining and forestry, where workers continue to face some of the highest rates of occupational illness fatalities in Ontario. WSN has developed a suite of specialized training materials and will work directly with employers and workers through hands-on coaching and real-time use of hygiene monitoring equipment. The IWH will support the initiative by applying its expertise in health and safety research to assess the effectiveness of the training programs and their impact on improving worker safety.

Study confirms: Excellence program helps small businesses make positive OHS change
According to a study by the Institute for Work and Health (IWH), small businesses participating in health and safety incentive programs, such as the Workplace Safety and Insurance Board (WSIB) Health & Safety Excellence Program (HSEp), are better able to make positive health and safety changes in their workplace, despite facing challenges like limited time and resources. Participants in these programs achieve significant benefits, such as increasing health and safety awareness and effective implementation of occupational health and safety (OHS) policies. However, small businesses often require additional support due to resource constraints and limited OHS knowledge.

Cannabis use by workers before and after legalization in Canada
On October 17, 2018, the non-medical use of cannabis was legalized in Canada. To examine the implications of this change for workplaces, the Institute for Work & Health (IWH) embarked on two research projects. The studies explored changes in cannabis consumption habits among workers; changes in their perceptions about such consumption; associations between cannabis consumption and occupational injury risks; as well as the use of cannabis to treat symptoms in the aftermath of a work-related injury/illness. This Issue Briefing provides an overview of findings from these two studies and the potential implications of this research for employers and policy-makers.
