To calculate the lost-time injury rate, we look at the number of allowed lost-time claims and the total number of people employed to determine the number of lost-time claims per 100 employees.

Since 2011, the number of people covered by the WSIB from Schedule 1 businesses has increased by approximately 10 per cent, while the lost-time injury rate increased by two per cent and the no lost-time injury rate decreased by 30 per cent. In 2020, employment numbers for those covered by the WSIB for Schedule 1 and Schedule 2 businesses decreased by 8 per cent compared to 2019. Similarly, Statistics Canada’s Labour Force Survey (LFS) on employment in Ontario showed a six per cent decrease in employment over the same period. 

The lost-time injury rate increased by two per cent and the no lost-time injury rate decreased by 30 per cent for 2020.

Saskatchewan, Manitoba, Nova Scotia, Newfoundland and Yukon have seen the biggest decreases, and Prince Edward Island and New Brunswick have increased.  Ontario currently has the lowest injury rate in Canada, while the WSIB and the other compensation boards across Canada continue improving overall health and safety in the workplaces across the province.

Data source for lost-time injury rate by jurisdiction:
Detailed Key Statistical Measures Report on the Association of Workers’ Compensation Boards of Canada (AWCBC) website pulled June 2021.

Data notations:
Data presented in the lost-time injury rate by jurisdiction graph reflect the latest complete year due to the lag in reporting for all Canadian jurisdictions.
The WSIB uses the term lost-time injury rate which is equivalent to the injury frequency statistic that is reported by the WSIB to AWCBC annually.

Differences in population, industry mixes, coverage, and legislation/policy may affect comparability between jurisdictions. These measures use standard definitions as compiled by AWCBC that may differ from individual workplace compensation board reports.
