This article examines occupational health and safety (OHS), with aparticular focus on youth apprentices. It uses quantitative and qualitativedata to examine the incidence of injuries among youth apprentices, and theirexperiences related to health and safety at work inCanada. Analysis of large-scale national surveys suggests a high incidence ofwork-related injuriesamong youth and low participation rates of youngerworkers in formal OHStraining. A survey of 173 former Ontario Youth Apprenticeship Program(OYAP) and Registered Apprenticeship Program in Alberta (RAP)participants finds that one-fifth suffered seriousoccupational injuries, whichrequired time off work. The results from this studyhave importantimplications for youth apprenticeship programs, particularly the OHS- andtrade-specific knowledge required for youth to worksafely during andfollowing their apprenticeship training.
