Illness/injury prevention

IWH has a long history of conducting research to provide practical guidance to employers, workers, OHS professionals and regulators about what works and what doesn’t in injury or illness prevention. This research targets the injury and illness prevention practices of workplaces, as well as the programs developed by governments, health and safety associations and others to support and motivate workplaces to adopt effective practices.

Safe work integration of newcomers: Employer perspectives

Employers play an important role in the safe and sustained work integration of immigrants and refugees in Canada.

In this presentation, Dr. Basak Yanar shares insights gained through a recently completed project on the work integration of newcomers. She discusses the perspectives of employers, as well as the experiences of immigrant-serving organizations that work with employers in promoting safe and sustainable work integration.

Evaluating the effectiveness of mandatory working-at-heights training standards

The introduction of a mandatory training standard for construction workers using fall protection equipment is associated with a 19.6 per cent reduction in the incidence rate of lost-time claims due to falls targeted by the intervention. This decline is larger than an overall decline in injuries in the sector during the same time frame. Reductions in incidence rates are also largest among the smallest employers.

Supporting settlement agencies to raise OHS awareness among newcomers

Newcomers to Canada face a higher risk of workplace injury and illness, due in part to a lack of knowledge about their OHS rights and responsibilities. Settlement agencies can help raise this awareness, but they also need support from the prevention system to do so, according to a recent project.
