The Consultants Directory has been prepared for persons interested in retaining the services of a consultant in occupational and environmental health and safety. Occupational and environmental health and safety issues continue to be addressed by management, workers and the general public in an effort to reduce the risk, both real and perceived, to health and safety.

Many workplaces from time to time require the assistance of experts or experienced professionals from various disciplines in the occupational or  environmental health and safety fields. This Directory has been developed to assist in finding an expert who may assist you. Persons contacting consultants using this Directory are encouraged to indicate that this was the source.

The Occupational Hygiene Association of Ontario (OHAO) has provided this directory as a source document for those who may wish to retain the services of a consultant but makes no comment on the qualifications or competence of consultants listed herein.
