The Ontario government has announced that employers are now required to post a new workplace poster, "Health & Safety at Work – Prevention Starts Here," pursuant to their obligations under the Occupational Health and Safety Act. This requirement will be enforced by Ministry of Labour inspectors beginning on October 1, 2012.

The poster was developed further to the recommendations of the Expert Advisory Panel which was appointed by the Minister of Labour in early 2010 to review Ontario's occupational health and safety system, and which tabled its recommendations in December 2010. The poster is available in multiple languages.
