Certificate of Recognition (COR) audit program


Effect of certification on injury rates

In brief

  • Occupational health and safety interventions, including regulatory approaches, programs, and management systems, are key strategies for reducing worker injury and illness.
  • Certificate of Recognition (COR) audit programs use voluntary audit-based certification as a way of recognizing or encouraging effective OHS practices. COR programs provide premium rebates to employers who meet certain occupational health and safety management benchmarks or who have implemented a return to work program for injured workers.
  • We conducted independent impact evaluations of the COR programs in BC and Alberta, to assess how participation has affected firms’ claim rates and health and safety experience.
  • Both the BC and Alberta evaluations found that certification is associated with lower injury rates. However, COR programs appear to be identifying good performers, and participation may be associated with other factors that are driving the injury rate reduction.

Next steps

  • We are currently assessing and developing the BC Construction Safety Alliance’s COR audit database, in preparation for a future investigation of the effect of the COR program on firm injury claim rates.
