What does "information the employer ought to be aware of" mean?
For the purpose of interpreting what information the employer "ought to be aware of", the following are considered to be sources of occupational health and safety information that the employer should know about:
publications and computerized information available from the Canadian Centre for Occupational Health and Safety;
publications available from industry or trade associations of which the employer is a member and from labour organization(s) representing workers at the workplace; and
publications from the Ontario Ministry of Labour. It is not expected that the employer would have to consult all of the above sources, nor is the employer limited to the above. Next
