While employer expenditures on occupational health and safety (OHS) in high income countries can be substantial, the financial benefits of these expenditures are not well described. The objective of this study is to apply a transparent methodology to estimate the financial return to employers from OHS expenditures in the Canadian province of Ontario. There were three phases in the study workplan: establishing an accurate estimate of the average direct cost of disabling work injury or illness; identifying employers in the construction, transportation and manufacturing sectors with a low incidence of work-related injury and illness; and the application of a set of plausible assumptions to estimate the financial benefits of OHS expenditures in this sample of employers with strong OHS performance. Financial benefits combined estimates of the tangible financial benefits arising from averted disabling work-related injury and illness and intangible financial benefits associated with improved employee retention and morale, improved production quality and strengthened corporate reputation. Applying these plausible assumptions, the average return on OHS expenditures was 1.24 for 289 manufacturing employers, 2.14 for 56 transportation employers and 1.34 for 88 construction employers. There was variation around these average return on investment values; 138 employers (32% of the sample) had an estimated return on investment less than 1.0, and 295 employers (68% of the sample) had a return on investment estimate greater than 1.0. The estimates of average financial return among large Ontario employers in three important economic sectors, while moderate, are positive, in the range of 1.24 to 2.14. These estimates are consistent with the range of estimates available from research in this field over the past decade.
