"Resigning a commission" is a bit of an anachronism. In Canada, one is enrolled in the military until one is released. An officer, after completing their initial basic training becomes commissioned and keeps that commission throughout his service. When he voluntarily releases, the commission becomes a moot point. No one asks you to "resign it". Mine's still hanging in a frame downstairs.
One point on terminology. You are using the term "from active duty" in a general sense. Canadians don't have "active duty". That's more an American term. Canadian soldiers are enrolled for "continuing, full-time military service" (i.e the regular force) and "other than continuing, full-time military service" (i.e. the reserve force).
During their careers, members may be involved in specific type of service. For example, under s 31 of the National Defence Act, members may be "placed on active service" by an order of the Governor in Council (ie the Federal Cabinet) in certain circumstances. For example, all regular force members are currently on "active service" for the purposes of Canada's commitments to NATO. The same for reservists when they are out of the country. In addition various members or contingents are "placed on active service" for various off-shore operations. This is quite different from the American concept of "active duty" which is more in the nature of our "continuing, full-time military service".
