The OHS Act & Regulations course has now been replaced with the Incident Investigation course as part of the compulsory training requirements. As such, all new applicants are now required to complete the new course requirement and write both national and provincial knowledge examinations. During the phasing period, applicants who originally applied under the CSO program will have the opportunity to choose between completing the OHS Act & Regulations course or the new Incident Investigation course as part of the compulsory requirements. However, as with the new applicants, individuals who originally applied under the CSO program will be required to write both national and provincial knowledge examinations.
