(Glossary of Heraldic Terms)
To design a badge for a ship named after the great St. Lawrence River many references are called upon. First the background of blue and gold, the colours of the French King are derived to represent the flowing river. The White or Arctic Whale is said to be the protective spirit of the river. The red grid is associated with St. Lawrence himself. The day that Cartier first entered the waters of the river coincided with the anniversary of the Saint's martyrdom, supposedly by roasting on a grid.
St. Laurent (I) was originally HMS Cygnet. She was commissioned into the RCN in February 1937. A member of the River class of destroyers, she wore pennant H83 until she was paid off in October 1945. St. Laurent (II) was the lead ship of the St. Laurent class of destroyer escorts. She was commissioned in October 1955. Later, she underwent conversion to the Improved St. Laurent class of DOH. She wore pennant 205 until she was finally paid off in June 1974.
