The Canadian Medical Association Journal is a peer-reviewed general medical journal published by the Canadian Medical Association (CMA). It publishes original clinical research, analyses and reviews, news, practice updates, and editorials.

The journal published Banting and Best's 1922 report, "Pancreatic extracts in the treatment of diabetes mellitus".

On February 20, 2006, the editor-in-chief John Hoey, was fired over an editorial independence dispute with the then owners of the journal, CMA Media. The journal sent 13 women to buy the emergency contraceptive levonorgestrel (Plan B) over-the-counter in pharmacies across Canada, and report their experiences. The pharmacists asked them for personal data, including the women's names, addresses, dates of last menstrual period, when they had unprotected sex, customary method of birth control, and reason for dispensing the medication. This was at the recommendation of the Canadian Pharmacists Association, which also advised members to store the information permanently in their computers. The Canadian Women's Health Network said that collecting this information was unnecessary and a violation of privacy. The Canadian Pharmacists Association complained to the Canadian Medical Association, demanding that the names of the pharmacists be removed from the article. The Canadian Medical Association ordered the journal to comply. The Canadian Medical Association then fired Hoey, without giving a reason.

His first two studio albums, Room for Squares and Heavier Things, did well commercially, achieving multi-platinum status. In 2003, he won a Grammy Award for Best Male Pop Vocal Performance for "Your Body Is a Wonderland."
