 As a consultant hired by homeopathy giant Boiron, Mulcair launched in November 2019 the company’s public relations campaign to get the Quebec government to create a professional order for homeopaths.As homeopathy is considered a pseudoscience and its preparations are not effective for treating any medical condition, Mulcair’s involvement in the campaign and the new organization Quebec Coalition for Homeopathy has been criticized by several Canadian science communicators, such as Olivier Bernard, Alain Vadeboncoeur, Timothy Caulfield as well as McGill University’s Office for Science and Society.After being voted out as NDP party leader, Mulcair spent much of the 2019 election criticizing Jagmeet Singh.
