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.

Ontario ministry could recommend changes to working-at-heights training
A testimony from William Roy, a senior Ministry of Labour, Training and Skills Development (MOL) policy manager, revealed potential changes to working at heights (WAH) training which could be implemented as soon as April.
The revelation came on day three on Ontario’s swing stage inquest into the 2009 scaffolding collapse at an Etobicoke high rise, in which four people died. Roy's testimony included suggestions for training reforms, contained in a Feb. 2019 report conducted by the Institute for Work & Health (IWH) and commissioned by the Ministry.

Work-related skin cancer among construction workers set to double by 2060
Cases of work-related non-melanoma skin cancer among construction workers in Ontario are on track to double by 2060. However, according to new research done by the Institute for Work & Health (IWH), if protective equipment and clothing such as long-sleeve shirts, pants and neck coverings are worn by construction workers, up to 6,034 cases of such cancers could be averted over the next three decades. That would result in $38 million in costs (in 2017 Canadian dollars) being saved over a 30-year period, Grant Cameron reports.

Updating a study on the union effect on safety in the ICI construction sector
IWH updated a previous study on the union safety effect in Ontario's industrial, commercial and institutional construction sector. Like the first study, the update found unionization was associated with a lower risk of injuries requiring time away from work, including both musculoskeletal and critical (more severe) injuries.
