Boric acid, its salts and its precursors
Boron-containing substances were identified as priorities for action for the second phase of the Chemicals Management Plan (CMP). The assessment focuses on boric acid, a common moiety of concern, and therefore considers boric acid, its salts and its precursors, including boron-containing substances that may release boric acid.

Updated draft assessment and revised risk management scope
In March 2025, the updated draft assessment and the revised risk management scope for boric acid, its salts and its precursors were released and the related notice was published in the Canada Gazette, Part I: Vol. 159, No. 10 – March 8, 2025 for a 60-day public comment period. The Government is proposing that boric acid, its salts and its precursors are harmful to human health and the environment at levels of exposure considered in the assessment.
The first draft screening assessment and the first risk management scope were originally released in July 2016 and the related notice was published in the Canada Gazette, Part I: Vol. 150, No. 30 - July 23, 2016 . Since then, new use and exposure information, including additional environmental monitoring and human biomonitoring data from the Canadian Health Measures Survey became available. As a result, the first draft screening assessment and the first risk management scope were updated.
