To calculate the lost time injury (LTI) rate, we look at the number of allowed lost time claims and the total number of workers employed to show the number of lost time claims per 100 workers.

Since 2007, the number of workers covered by the WSIB for Schedule 1 firms has increased by approximately 11 per cent while the lost time and no lost time injury rates have declined by about 39 per cent and 37 per cent, respectively.

In 2016, covered employment for Schedule 1 and Schedule 2 firms increased by two per cent compared to 2015. Similarly, Statistics Canada’s Labour Force Survey (LFS) on employment in Ontario showed a one per cent increase in employment over the same period.

Jurisdictional Comparison

Over the past 10 years, injury rates among all the provinces and territories have declined, with Ontario, Saskatchewan, Manitoba and Quebec seeing the largest decreases.  The WSIB and workplace compensation boards across Canada continue working to improve overall health and safety in the workplace.


Injury Frequency by Canadian Jurisdiction

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 May 2017.

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 LTI 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.
