In the Royal Canadian Navy, leading seaman is senior to the rank of able seaman, and junior to master seaman. Its Army and Air Force equivalent is corporal and it is part of the cadre of junior non-commissioned officers. Leading seamen are generally initially addressed as "Leading Seaman Smith", and thereafter as "Leading Seaman". The same rank title is used for female members. The slang term for the rank is "killick", as in the Royal Navy. The term is still used even though the old-style insignia of a fouled anchor is no longer used for this rank in the RCN. Leading seamen generally mess and billet with other seamen and their army and air force equivalents: privates, corporals, and master corporals. Their mess on naval bases or installations is generally named the "junior ranks mess".
