The consultation on occupational exposure limits – Grain and flour dust, took place between June 10, 2017 and July 10, 2017. We would like to thank everyone who gave us their comments during this consultation. The online survey that was available during this period is no longer active.


The Labour Program is holding an online consultation on the proposed amendments to the Occupational Exposure Limits (OELs) for grain dust and flour dust in federally regulated workplaces.

The proposed regulatory amendments to the Canada Occupational Health and Safety Regulations (COHSR) and the Maritime Occupational Health and Safety Regulations (MOHSR) would:

  • decrease the current OEL for grain dust from of 10 mg/m3 to 4 mg/m3; and
  • increase the current OEL for flour dust from 0.5 mg/m3 to 3 mg/m3.

Regulatory Impact Analysis Statement


The Government of Canada is proposing amendments to the Occupational Exposure Limits (OELs) for grain dust and flour dust in federally regulated workplaces. These proposed changes would improve worker health and safety while also accounting for economic and technical feasibility as well as consistency with other Canadian and international jurisdictions.


Stakeholders and Canadians have the opportunity to submit comments during the pre-publication of the proposed amendments in Part I of the Canada Gazette, from June 10 to July 10, 2017.
