Canada has the highest number of lakes in the world, estimated to contain over two million lakes. This abundance is due to its vast size and glacial activity from the last Ice Age, which created numerous depressions filled by melting ice. The lakes vary greatly in size, from tiny ponds to large bodies of water like Lake Superior. These lakes not only enhance the natural beauty of Canada but also play a vital role in its ecosystem, providing habitats for many species and contributing to the country's freshwater resources.
