In Army Cadets, air rifles are used at the corps level for teaching marksmanship concepts. Aunshutz .22 are also used by corps with biathalon teams. The CF still contracts for "standard velocity) .22 for the biathalon teams.
Air rifles are also used at summer camps, but cadets often also have the option to fire the C7 for familiarization. (20 rds, semiauto only). Drill and Ceremonial course cadets fire the .303s on final parade for a "fue de joi".
At Connaught, cadets who have proven themselves in marksmanship at the corps, region, or camp level, will shoot "fullbore" C11 (5.56 CF target rifle) and C12 (7.62 CF target rifle) to get onto the Bisley team.
Colt Canada pitched the "C10" cadet rifle a number of years ago but was unfortunately turned down. The C10 was to be a dedicated .22lr bolt action C7/AR15), with "friendly" all wood furniture. Since many parts would be common to the C7 it would cut down on training and parts costs related to maintenance, and the wood furniture was designed to take away the "assualt rifle" image, plus the .22lr bolt idea was an excellent "PC" idea for a light, versatile local training cadet marksmanship rifle at any cadet corps with access to the local range. Also, cadets could scrap the Enfield DPs in favour of the C10 and follow the CF drill manual for rifle drill. However, some pantywaist kiboshed the idea, and it never happened.
