The major governing body of the Legion is the Dominion Convention which convenes every two years. The Dominion Executive Council (DEC), made up of representatives from each of the Provincial Commands, meets twice a year when Dominion Convention is not in session. In the period between meetings of the DEC, the Legion is run by the Sub-Executive Committee made up of the Legion officers elected at the Dominion Convention. Sub-Executive members chair the Legion's Dominion committees which include Veterans, Service and Seniors, Constitution and Laws, Youth, Poppy & Remembrance, Membership, Defence, Sports and Unity.
The 44th Dominion Convention will be held in Halifax, Nova Scotia during the period 09 – 13 June 2012.
