There is no such medal as what you have described.
May I suggest that what you mean is a Distinguished Conduct Medal awarded to a member of the Princes Patricia‘s Canadian Light Infantry.
If so this is a round silver medal with an ornate scroll clasp on top, the front of the medal has a image of King George the Fifth, it‘s reverse has the embossed legend "For Distinguished Conduct in the Field"
The ribbon is three equal stripes of crimson-blue-crimson.
This might also mean the 1914-18 Medal, the 1939-45 Star, or CVSM...there are images of medal ribbons at my site at http://www.canadiansoldiers.com - look under INSIGNIA...can you post a photo of the medal itself for us?
