Rates of work injuries have declined in Ontario, except the most severe

Past research in occupational health and safety, including studies conducted at IWH, has shown a general decline in rates of work-related injuries in Ontario over the past two decades. But a new IWH study, based on emergency department records from 2004 to 2017, shows that when it comes to very severe injuries, no such decline was seen among men. It also finds an increase of 18 per cent among women.

How do employment support programs impact the health of young adults with episodic disabilities?

The unpredictable and often invisible nature of episodic disabilities can make it challenging for workers to find and sustain employment while managing their fluctuating symptoms and work demands. For young adults navigating early career phases, these challenges may also have life-long impacts on their career progression and health. Researchers on an IWH study set out to investigate whether employment support programs for young adults with episodic disabilities may also impact their health.

IWH Speaker Series recording: Is precarious employment an occupational hazard?

Precarious employment has become more common in the Canadian labour market, as well as in the labour markets of other high-income countries. In this presentation, Dr. Faraz Vahid Shahidi examines the consequences of precarious employment for health and safety at work. Drawing on compensation claims data, Dr. Shahidi asks whether workers exposed to precarious employment – such as temporary, part-time, and low-wage jobs – are more likely to experience an occupational injury or illness.

What can work-related COVID-19 cases tell us about how to prepare for the next pandemic?

To what extent did workplace exposures account for the transmission of the COVID-19 virus during the first two years of the pandemic? A new study by IWH combined data sources to estimate work-related infection rates, using a method that took into account major shifts in where people worked. It found the role of work exposure changed from wave to wave, in a dynamic pattern not in keeping with the number of cases in the general population.

IWH Speaker Series recording: Estimating the risk of workplace COVID-19 in different phases of the pandemic

The role of work exposure was at the heart of much public debate about policy decisions during the COVID-19 pandemic. But getting estimates of rates of work-related COVID infections was made all the more challenging by the overnight shift from in-person work to remote work, across many sectors of the economy. Watch a recent IWH Speaker Series presentation by Dr. Peter Smith, as he shared findings from a study that examined how occupational exposures were associated with work-related COVID-19 risk, taking into account these major changes in where and how people worked.
