Construction sector

IWH research that specifically involves construction workplaces, workers, unions, employers and/or associations, as well as research on programs that specifically target the construction sector, is collected together here. Not included is IWH research that cuts across all or many sectors, even though it may be relevant to the construction sector. For this reason, visitors are encouraged to explore beyond this page to find equally important information on the prevention of work injury and disability in construction.

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.
