Canada adopted the same pattern and used a lion on the shield's right holding a gold pointed silver lance from which flies the Royal Union flag, and a unicorn with gold horn, mane and hoofs, on the shield's left.
Canada's motto "A Mari usque ad Mare" is based on biblical scripture: "He shall have dominion from sea to sea and from the river unto the ends of the earth (Psalm 72:8).
