Here's some tidbits about Canada from this site.
http://atlas.nrcan.gc.ca/site/englis...ergeneral.html
The total area of Canada is 9 984 670 square kilometres
The Great Lakes - Superior, Michigan, Huron, Erie and Ontario - are the largest group of freshwater lakes in the world. They have a total surface area of 245 000 square kilometres.
That puts the Great Lakes just a little bigger than the UK.
