COVID-19

COVID-19 was declared a global pandemic by the World Health Organization on March 11, 2020. In short order, the world of work changed dramatically in Canada. Non-essential businesses were locked down. Some workers lost their jobs; others were sent home to work. Despite protections, workers in sectors ranging from health care to transportation to food production and retail faced risk of infection, illness and even death. IWH research examines the impact of the pandemic on workers and workplaces, as well as the lessons for work and health policy-makers to prepare for the next pandemic.
