OHS incident investigations

OHS incident investigations

OHS investigates serious work site incidents, including fatalities, which fall under provincial legislation.


What’s important to know

By law, OHS can only investigate incidents at work sites that fall under provincial OHS legislation. Serious incidents are defined in Section 18 of the OHS Act.


After a serious incident or fatality takes place at a work site:

Step 1

OHS officers investigate the work site to determine the causes and circumstances of the serious incident or fatality.

Step 2

OHS prepares an investigation report summarizing the incident.

Step 3

OHS conducts an enforcement action review of the investigation, to determine if the incident file should be submitted to Alberta Justice for consideration for prosecution.

Step 4

After incident files are reviewed by Alberta Justice, charges are laid if there’s a reasonable likelihood of a conviction, and a prosecution is in the public interest.

Step 5

If charges are laid, the defendant can be acquitted, be found guilty, or have their charges withdrawn or stayed.

Step 6

OHS publishes fatality investigation reports online after investigations and all court proceedings, if any, are completed.

OHS also issues industry notices about fatalities at Alberta work sites.

In case of any inconsistency between this information and the OHS Act, Regulation, Code, the legislation will always prevail.
