Ontario Leading Indicators Project

We’re looking for managers and supervisors who have supported workers with chronic diseases to take part in this study

If you're a manager or supervisor with experience accommodating employees with chronic physical or mental health conditions, we’d like to talk to you about the challenges you have experienced in supporting these employees while also balancing privacy needs. Your participation would consist of a confidential phone interview of about 30 to 40 minutes.

If interested, please email jbowring@iwh.on.ca or call 1-855-884-1416.

Objectives of the study

The Ontario Leading Indicators Project (OLIP) was a study conducted by the Institute for Work & Health (IWH) from 2011-2014 in partnership with Ontario’s health and safety associations (HSAs) to develop leading indicators of occupational health and safety (OHS) performance. The HSAs included Workplace Safety & Prevention Services (WSPS), Workplace Safety North (WSN), Public Services Health & Safety Association (PSHSA) and Infrastructure Health & Safety Association (IHSA). The aim was to identify organizational and management measures that help predict workplace injuries and illnesses, allowing workplaces and system partners to gauge health and safety performance before injuries and illnesses occur.


Researchers developed the OLIP questionnaire with input from OHS practitioners and workplace parties. The OLIP questionnaire was made up of five existing survey measures: Organizational Policies and Procedures (OPP), IWH Organizational Performance Metric (IWH-OPM), Occupational Health and Safety Management Systems (OHSMS), Safety Climate, and Joint Health and Safety Committee (JHSC) Index.

To test the measures, IWH created a list of organizations in Ontario randomly chosen from among firms registered with the Workplace Safety and Insurance Board (WSIB). From 2011 to 2013, the HSAs recruited approximately 2,000 organizations from among this list to take part. The organizations were from 10 different sectors, of all firm sizes and from across all regions of Ontario. These organizations completed a 20-minute online survey, which asked about workplace health and safety policies and procedures. In return, organizations received an individual benchmarking report. In 2014, the survey was opened up to all organizations, who also subsequently received individual benchmarking reports.

Based on the responses of the 2,000 organizations, IWH was able to produce benchmarks. Because participants in the OLIP study were from a known population (i.e. firms registered with the WSIB), researchers were able to weight the data by organizational size and region to make the benchmarks representative of all organizations in the sector in Ontario. Since not all firms were equally likely to participate in OLIP, researchers used propensity scores to further make the benchmarks representative of all organizations in the sector. The propensity scores equation was developed by IWH and is unique to OLIP benchmarking results. Note that these benchmarks reflect company scores collected from 2011 to 2014.
