Training officer at naval fleet schools or Naval Reserve divisions
Executive officer of a minor warship or submarine
Staff officer on a formation or task group headquarters staff.

The rank insignia for a lieutenant is two ½-inch stripes with the executive curl on the top stripe, worn on the cuffs of the service dress jacket, and on slip-ons on other uniforms. As junior officers, they wear one gold band along the edge of the visor of their service caps. Lieutenants of the Naval Operations Branch wear the officer's pattern of the branch cap badge: an anchor on a black oval, surrounded by a wreath of maple leaves at the sides and base of the oval, the whole surmounted by the St Edward's Crown. Specialist officers in such branches as logistics, intelligence, medical, etc., wear their branch cap badges.
Prior to unification of the Canadian Forces in 1968, rank structure and insignia followed the British pattern. As part of the Canadian Naval Centennial the executive curl pattern of naval officer's rank was returned to all uniforms.
