1998-1999

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).

2000-2002

• Dr Seal became the first two-year term President of the CAS, following the implementation of changes to the Bylaws and organizational structure of the CAS.
   
• Dr Eva Ryten presented her ACUDA-sponsored report, A Physician Workforce Planning Model for the Specialty of Anesthesia: Theoretical and Practical Considerations.  This report included a model for predicting province-specific anesthesiologist human resource requirements to the year 2016. 
   
• An anesthesia assistant category was added to CAS membership. 
   
• Canadian Anesthesia Day: This day was undertaken in 2000 as part of a “grassroots” level public awareness and image improvement project for our specialty.
   
• MOCOMP: This RCPSC initiative was implemented in January 2001.  The CAS took the necessary steps to become a MOCOMP accreditor recognized by the RCPSC which would enable the CAS to accredit its Annual National meeting as well as divisional and regional meetings.  In later years, this included accreditation from allied health societies.
