A vice-admiral is a flag officer, the naval equivalent of a general officer. A vice-admiral is senior to a rear-admiral and major general, and junior to an admiral and general.

The rank insignia of a Canadian vice-admiral is as follows:

 * On tropical white mess dress and tropical white service dress tunic: three gold maple leaves, beneath crossed sword and baton, all surmounted by a St. Edward's Crown located on gold shoulder boards.

Two rows of gold oak leaves are located on the black visor of the white service cap. From 1968 to June 2010, the winter service dress tunic featured only a wide gold braid around the cuff with three gold maple leaves, beneath crossed sword and baton, all surmounted by a St. Edward's Crown located on cloth shoulder straps.

Vice-admirals are addressed by rank and name; thereafter by subordinates as "Sir" or "Ma'am". Vice-admirals are normally entitled to a staff car; the car will normally bear a flag, dark blue with three gold maple leaves arranged one over two.

A vice-admiral generally holds only the most senior command or administrative appointments, barring only Chief of Defence Staff, which is held by a full admiral or general. Appointments held by vice-admirals may include:
 * Vice-Chief of Defence Staff (VCDS);
 * Deputy Chief of Defence Staff (DCDS);
 * Commander of an operational command (such as Canadian Joint Operations Command);
 * Chief of the Maritime Staff (CMS);
 * Assistant Deputy Minister (ADM) of Defence in various capacities;
