Special Service Medal (Canada)
The Special Service Medal () is a service medal awarded to members of the Canadian Forces. The medal was established by letters patent by Queen Elizabeth II on 16 June 1984. Recipients of this medal must have performed, "service under exceptional circumstances". The medal is always issued with a bar which specifies the special service which the medal recognizes. Each bar has its own criteria. Appearance
The medal is made of copper and zinc alloy and is circular,  in diameter. The obverse depicts a maple leaf surrounded by a laurel wreath. The reverse contains the inscription "SPECIAL SERVICE SPÉCIAL", curving along the bottom edge of the medal. In the centre is the St Edward's Crown and Royal Cypher. A single-toed claw attaches at the top of the medal suspending it from a straight slotted bar, which hangs from the medal's ribbon. The ribbon is  wide. It has a dark green centre stripe flanked by white stripes, with red stripes at the edge. The white and red stripes are the same width. The bars are sewn to the medal's ribbon. These bars are made of silver coloured metal, with a raised border and the name of the qualifying special service on a pebble textured background. To indicate additional awards of the medal, upon the ribbon bar, a silver maple leaf is worn to indicate two awards of the medal, gold for three and a red maple leaf for four. Bars
