How might a conservation biologist apply the theory of island biogeography in a national park
1 . Canadian English is an odd duck, a weird amalgam of American English and our British roots. 2  Canadian spelling keeps the 'u' in words like honour, colour and valour. 3  Canada switched over to the metric system decades ago, while the U.S. is one of the few countries that still use the imperial system.
It is CA. The international abbreviation for Canada is CA. Nothing to do with .ca or the internet. California, or Cal or CA (Cal) is something different. Anything bound for shipment to Canada is marked CA. Provinces are also two letters. Who ever said the country is 3 letters and provinces two, needs some education in the matter.
