Explanation:

The Canadian population is approximately 37,500,000, mostly concentrated in the big cities of the south: 75% of the Canadian people live less than 330 kilometers from the border with the United States, an unmanned military border and the longest border in the world, spanning over 8,000 km.  This is due to the climatic characteristics of the country, whose position at the north end of the continent means that most of the country has temperatures below zero degrees during most of the year. More than 25% of the Canadian population is concentrated in only 3 cities: Toronto, Montreal and Vancouver. There are also other major cities such as Calgary, Edmonton, Ottawa, Quebec City, Winnipeg and London.
