The original logo was designed by Wesley Bourne in 1920, the then CAS Secretary. The inspiration for the motto came from Dean Moyse, of McGill University, and the artist was A Sherritt Scott RCA, who being a Scotsman decided to throw in a few thistles as well as poppies.

The logo and the motto were changed in 1999 following a vote at the Annual Business Meeting in 1998. The following changes were also made in order to improve public awareness concerning the role of anesthetists in Canada:

  • "Anesthetist” was a very confusing term for the lay public in Canada, so the reference to CAS members was changed to “anesthesiologist.”

  • Hypnos with his motto in Greek letters, was perceived as being completely meaningless to the average Canadian, so a new emblem and motto were needed.

  • A new slogan was developed for interaction with media and the public: “Canadian Anesthesiologists: Specialist Physicians in Perioperative Medicine, Critical Care and Pain Management”

  • Finally after much consultation, the simple red maple leaf emblem with an Aesculapian staff in purple was chosen.

  • The motto became Science. Vigilance. Compassion. (the same in French and English).

  • The Canadian Society of Anaesthetists became The Canadian Anesthesiologists’ Society (diphthong removed).
