Health care sector trends

Overview of injury data

Health and community care services are provided in a variety of settings. The health care sector is comprised of establishments that provide the following services:

• health care by diagnosis and treatment
• residential care for medical and social reasons
• social assistance, such as counselling and other community care services

The number of workers in the health care sector is generally increasing. Table 1 contains data from Statistics Canada that shows that the labour force in the health care and social assistance sector is increasing.

Lost-time injuries are injuries that occur in the workplace that result in the worker having to miss work.

According to data from the Workplace Safety and Insurance Board (WSIB), the lost-time injury (LTI) rate in the health care sector was 2.43 workers, per 100 workers in 2024.

The number of allowed claims during 2023 and 2024 decreased considerably from a high during 2022 and this reflects the reduction in the number of claims made in the sector related to COVID-19 occupational illnesses.

Table 2 shows the number of LTIs, the LTI frequency rate, and the number of no lost-time injuries (NLTIs) for Ontario’s health care sector from 2020–2024.

From the data shown it is clear that “exposures” has seen the most dramatic decrease in the past two years (2023 and 2024) which reflects the COVID-19 pandemic recovery and the decrease in exposure to COVID-19 and related occupational illness claims.

Occupational health and safety events and injuries

Occupational health and safety events and injuries reported to the Ministry of Labour, Immigration, Training and Skills Development (MLITSD) are summarized in Table 6.

Statistical notes

• Only critical injury events reported to the ministry are included.
• This represents data that were reported to the ministry and may not represent what actually occurred at the workplace.
• 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.
