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.

Rates of work injuries have declined in Ontario, except the most severe
From 2004 to 2017, rates of work-related injuries requiring an emergency department visit declined in Ontario. But that overall downward trend was driven by injuries that were mild or moderate in severity. Rates of very severe injuries did not fall among men and even increased among women.

Regulated working at heights training works and needed: studies
Two recently released Ontario studies demonstrate why mandatory, standardized working at heights training is so critical to worker well-being. One study undertaken by the Institute for Work & Health (IWH) conducted an evaluation of the impact the province’s working at heights training standard had on workers and their work sites. A second and earlier probe prepared by the Ministry of Labour (MOL) for the Chief Prevention Officer undertook root cause analysis of worker deaths from falls from heights.

Opinion: Avoid shoddy work by using unionized tradespeople for public construction projects
Why do many municipalities, school boards, social housing corporations and other public bodies have long-standing arrangements that see their construction projects built by skilled tradespeople who are members of construction unions? Because the employees are well trained, they work safer and, in the long run, are not a significantly greater cost to the taxpayer than their non-unionized counterparts, writes Phil Gillies in an op-ed that cites Institute for Work & Health research.
