Small business health and safety
IWH research that specifically looks at injury prevention, return to work and other work-health issues in small businesses is collected together here. However, not included is IWH research that cuts across all sizes of business, including small business. For that reason, visitors are encouraged to explore beyond this page to find equally important information on the prevention of work injury and disability in small businesses.

New business owners on why and how OHS starts to matter
New businesses make a substantial contribution to the economy, with roughly 100,000 created a year in Canada. New businesses and their owners are expected to begin managing occupational health and safety (OHS) by the time they hire their first employee. But against the many demands for their attention, when, why and how does OHS begin to matter to new business owners? In this presentation, a companion piece to a presentation from last year based on survey findings, Dr. Basak Yanar shares insights from interviews with new business owners on how they begin managing OHS and what supports they need.

Strengthening workplace safety for small business workers
Small businesses often experience higher worker injury and fatality rates than large organizations in the same sector due to limited health and safety knowledge and resources. A recent study conducted by the Institute for Work & Health (IWH) addressed gaps in research on new businesses – often classified as small businesses – and occupational health and safety (OHS).

New small businesses often lack basic safety management, IWH study finds.
About 100,000 businesses are created in Canada each year that will employ workers. Many of these new firms are small and staffed by short‑tenure employees, two factors linked to higher injury risk. But as Shane Mercer reports, in an IWH study sample, only a tenth has put in place all available safety measures, while as many as a quarter has implemented none.

How new businesses get their start in workplace health and safety: implications for research and policy
New businesses are too seldom the focus of occupational health and safety (OHS) research even though they may present risks to worker health and safety. To better understand how new businesses start engaging with OHS, a study team conducted a survey of owners of new Ontario businesses from diverse sectors. In this presentation, Dr. Lynda Robson shares results from the study. She discusses what study participants reported about their OHS management activities, OHS information sources, experiences with the Ontario OHS system, barriers to taking OHS actions, and preferences for receiving OHS information. The presentation also highlights factors associated with OHS management initiation, the value of applying a research-based behaviour change framework to the study, and the implications of the study for research and policy.

IWH study reveals gaps in health and safety knowledge about new businesses
Workers in small businesses have higher rates of work-related injuries and fatalities than those in larger businesses, even within the same sector. To best prevent injuries, OHS management in these businesses should start early in their life cycle. But according to a new IWH study, few programs or policies are specifically aimed at helping new businesses start managing OHS.

Study confirms: Excellence program helps small businesses make positive OHS change
According to a study by the Institute for Work and Health (IWH), small businesses participating in health and safety incentive programs, such as the Workplace Safety and Insurance Board (WSIB) Health & Safety Excellence Program (HSEp), are better able to make positive health and safety changes in their workplace, despite facing challenges like limited time and resources. Participants in these programs achieve significant benefits, such as increasing health and safety awareness and effective implementation of occupational health and safety (OHS) policies. However, small businesses often require additional support due to resource constraints and limited OHS knowledge.
