The Occupational Safety and Health Administration (OSHA) announced in late May that it will continue its partnership with Health Canada to align United States and Canadian regulatory approaches to labeling and classification requirements for workplace chemicals.

OSHA aligned its Hazard Communication Standard with the GHS in March 2012 to provide a common, understandable approach to classifying chemicals and communicating hazard information on labels and safety data sheets. Canada published a similar regulation in February 2015.

The goal of the partnership is to implement a system allowing the use of one label and one safety data sheet (SDS) that would be acceptable in both countries. In 2013, OSHA and Health Canada signed a Memorandum of Understanding to promote ongoing collaboration on implementing the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) in their respective jurisdictions.
