UBC assessed the effect of COR certification on firm-level injury rates in BC by comparing certified firms to similar, but non-certified, firms from 2002
An earlier version of this work provided to WorkSafeBC in 2015 found that COR certification was associated with lower injury rates. This update and extension adds several years of follow-up, uses a revised 2014 serious
injury definition, and employs an improved analytical technique to better match certified firms to similar non-certified firms—in order to provide causal estimates of the effect of certification on injury rates.
In summary, the study found that:
- 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’ injury rates and health and safety experience.
- Both the BC and Alberta evaluations found that certification is associated with lower injury rates. Detailed results are available in the research briefs at right.
