Rising temperatures are projected to have a large negative impact on productivity, expecially in economic sectors where work takes place outdoors or in poorly cooled spaces. For undustries, occupational heat stress directly threatens workers' ability to live healthy and productive livest. While the economic impact to Ontario remains unclear, with the projected increase in temperatures to be amonst the highest in Canada, labour loss due to occupation heat stress may cause wealth inequalities for Ontario industries.
Rising temperature could result in the loss of 128 million work hours annually by end of the century --the equivalent of 62,000 full-time equivalent workers, at a cost of almost $15 billion.
Productivity losses associated with depression currently cost about $34 billion per year in Canada.
Productivity losses will also occur due to Ontario's hot humid summers causing high humidity, which limits the evaporation of sweat necessary to cool the body.
Heat-related occupational injuries will also rise including those not directly related to heat such as falls, slips, and trips - leading to a rise in worker compensation claims.
