Health Canada Hotlist – Upcoming Changes 

The Cosmetic Ingredient Hotlist is an administrative tool used by Health Canada to communicate to manufacturers and other stakeholders that certain substances, when present in a cosmetic, may contravene the general prohibition found in section 16 of the Food and Drugs Act or a provision of the Cosmetic Regulations. This list is not exhaustive, and those selling cosmetics must not wait for a regulatory or Hotlist update to comply with the general prohibition. The sale of a cosmetic should stop as soon as it is known that the cosmetics may cause injury.  

The Hotlist is updated periodically based on scientific evidence, international standards, and stakeholder input. While it is not a formal consultation process, Health Canada invites stakeholders to provide safety information or other considerations about the proposed substances before finalizing updates.
