Background

The Ministry of Labour, Immigration, Training and Skills Development keeps a record of:

  • visits to workplaces by occupational health and safety inspectors
  • events that are reported to the ministry, including fatalities, critical injuries, complaints and work refusals.

We use this data and data from sources such as the Workplace Safety and Insurance Board to help plan health and safety compliance campaigns and initiatives.

Statistical notes

  • Only critical injury events reported to the ministry are included for each sector.
  • This represents data that was reported to the ministry and may not represent what actually occurred at the workplace.
  • Some events may not have been classified under a specific subsector at the time data was downloaded for this report.
  • The critical injury numbers represent critical injuries reported to the ministry and not necessarily critical injuries as defined by the Occupational Health and Safety Act (OHSA).
  • Non-workers who are critically injured may also be included in the ministry's data.
  • The Ministry of Labour, Immigration, Training and Skills Development tracks and reports fatalities at workplaces covered by the OHSA. This excludes deaths from natural causes, deaths of non-workers at a workplace, suicides, deaths as a result of a criminal act or traffic accident (unless the OHSA is also implicated) and deaths from occupational exposures that occurred many years ago.
  • Data subject to change because of inspectors' updates to the database.
