Enhanced Compliance

Apprenticeship and Industry Training (AIT) / Occupational Health and Safety (OHS)

The Enhanced Compliance initiative provides OHS Officers with another tool to improve worker safety, while at the same time increasing compliance under the Apprenticeship and Industry Training (AIT) Act.

OHS Officers are ONLY responsible for compliance in the 10 apprenticeship compulsory trades, and do not have the full authority of an AIT Officer. The intent of this initiative is to provide additional reach to job sites and for OHS Officers to compliment OHS inspections with an additional tool:  the AIT Act and specific program regulations.
