The GCS is a gold-coloured four-pointed star, 44 mm across, representing the cardinal points of a compass bearing on the obverse, built-up in order from the back: a wreath of maple leaves terminating at the top with the Royal Crown, two crossed swords, the blades and hilts forming four additional points to the star, an anchor and a flying eagle. The wreath represents honour, the maple leaves represent Canada, the anchor, crossed swords and eagle represent the three services of the Canadian Forces and the Crown represents the Queen of Canada and her role as the fount of all honours. On the reverse appear within a raised circle, from top to bottom: the Royal Cypher ensigned by the Royal Crown, a plain space for engraving, and three maple leaves on one stem.
The ribbon passes through a ring attached to a small ball at the top point of the star.
The ribbon is 32 mm wide with a central stripe of green (12 mm), on either side of which are stripes of white (2 mm) and red (8 mm). Red and white are the official colours of Canada as appointed by King George V in 1921 and green represents service.
The bars to the Star are gold in colour with a raised edge and bear the name of the operation or the geographical area for which it is awarded.
