On 30 July 1980, Queen Elizabeth II augmented the armorial bearings by Royal Warrant with a crest, supporters, and a motto. The helmet under the crest was changed from a steel helmet to a gold royal helmet on 15 January 2008.
The crest sits above the shield and consists of a royal helmet crowned with a red and silver wreath, on top of which sits a beaver, resting on top of which is St Edward's Crown. White and red are the official national colours of Canada, and the beaver is the official animal of Canada.
The shield represents the natural resources and beauty of the varied Alberta landscape: the Rocky Mountains and their foothills, the grass prairies, and the cultivated wheat fields. The St George's Cross is an allusion to the arms of the Hudson's Bay Company, which once controlled what is now Alberta.
The supporters sit on either side of the shield and consist of a golden lion on the left (representing power) and a pronghorn on the right (representing Alberta's natural resources). Neither of these is the official animal of Alberta (which is the bighorn sheep).
