These arms have been downloaded from Canadian Heraldry. The cross of St. George in the chief represents the British heritage of many Manitobans (as well as the Hudson's Bay Copmpany, which did much to open Manitoba to the rest of Canada), as does the unicorn (which is also a supporter of the arms of Scotland and Britian). The bison was once quite common on the plains of Manitoba. The horse was once a fundamental mode of transport on the plains, and the beaver is a very Canadian sort of crest. The prairie crocus (the purple flower held by the beaver and in the middle of the compartment) is the provincial emblem of Manitoba, and is unique in having a fur coat (probably necessary, since it is usually the first flower to bloom on the prairies after winter is over). The rest of the compartment represents the agriculture (wheat) and forestry industries of Manitoba and its waterways. The motto is Latin for "Glorious and Free", taken from the national anthem of Canada. The other emblems can be found here.
