  • I’ve spent over 30 years as a health and safety professional. I started my career with The Metropolitan Toronto Police Force in March, 1978 as a Police Officer and have divided my experience with The Ontario Ministry of Labour where I was appointed as an Occupational Health and Safety Inspector and Provincial Offences Officer where I was responsible for administering and enforcing the Occupational Health and Safety Act and its Regulations.  I am also a licensed paralegal by the Law Society of Upper Canada.

    I was also appointed as a federal WHMIS Inspector by Health Canada and was the certified worker representative on the Ministry of Labour’s (York District Office) Joint Health and Safety Committee for 6 years, for which I was elected by my colleagues. During my tenure at the Ministry of Labour, I was also appointed and authorized to conduct examinations, investigations and inquiries under subsection 135(1) of the Workplace Safety and Insurance Act and additionally authorized to perform audits, investigations, inspections and demand information for the Ministry of Finance pertaining to the Retail Sales Tax Act, the Corporations Tax Act and the Employers Health Tax Act.

    My duties as an Inspector for the Ministry of Labour included but not limited to investigations into workplace accidents, complaints, disputes, work stoppages and work refusals to determine compliance with legislation, regulations and standards by; gathering all relevant information and evidence, interviewing employer and worker representatives, witnesses and related parties; conducting physical inspection of workplaces to identify hazards and contraventions; discussing matters such as unresolved health and safety concerns; observing and assessing hazards.

    My responsibilities also required the conduction of unannounced workplace inspections by examining and assessing effectiveness and compliance of occupational health and safety practices including worker education and training programs.

    Also a member of The Canadian Society of Safety Engineering.
