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.

Study shows worker injuries due to falls from heights declined after Ontario made training standardized and mandatory
Among recent organized efforts to make jobsites safer, working-at-heights training has been effective, reports an Institute for Work & Health (IWH) study. As Adam Freill reports, in the three-year period after Ontario made working-at-heights training in the construction sector standardized and mandatory, study authors explain that the rate of fall-from-height injuries leading to time off work fell by 19 per cent.

Preventing falls from heights in construction: a long-term evaluation of Ontario's working-at-heights training standard
In 2015, the province of Ontario implemented a working-at-heights (WAH) training standard requiring most construction workers to take a specific day-long training in fall prevention. A 2019 study conducted by the Institute for Work & Health found the training had positive impact on construction workers' safety knowledge, work practices and injury rates. In this presentation, Dr. Lynda Robson shares new findings on the longer-term impact of the training, drawing on two additional years of follow-up data.

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.
