From Health Canada:
To help cosmetic manufacturers satisfy the requirements for sale of a cosmetic, Health Canada developed the Hotlist – a list of substances that are restricted and prohibited in cosmetics.
This September 2009 Cosmetic Ingredient Hotlist replaces the March 2007 version. Please refer to the document entitled “September 2009 changes to the Cosmetic Ingredient Hotlist” to view the changes made.
