Here's the passage...
"A lake may be defined as any inland body of standing water, usually freshwater, larger than a pool or a pond. Canada is famous for its number of lakes. There are at least as many as two million lakes of all sizes covering, in total, 8.9 per cent of the country. Also, Canada has 563 lakes with a surface area greater than 100 square kilometres. A complete list is given in the Facts about Canada section of The Atlas of Canada. The largest set of lakes, the Great Lakes, straddle the Canada–United States boundary, accounting for 18% of the world's freshwater in lakes."
