Around one fourth of the population in Canada lives in the province of Quebec.
Explanation:
Canada is the second largest country in the world, but its population doesn't reflect the size of the country. The reason for the relatively small population of Canada is that the majority of the country has extreme climate conditions and the land is not arable, thus large populations can not be sustained. Much of the country falls in the sub-polar and polar climate zones. Only the southern portion of Canada provides suitable living conditions, so the majority of the population is concentrated in relatively small part of the country.
Canada has a population of around 35 million people (2011 census), but as mentioned it is very unevenly distributed.
Ontario is the province that has the largest population in Canada, comprising for around a third of the total population.
Quebec is the second most populated province in Canada, making up for slightly less than one fourth of the total population.
Quebec is one of the most densely populated provinces of Canada because it has milder climate by being located in the southeastern part of the country. It also comes out on the Atlantic Ocean, which makes the climate milder, but also enables the region to use the ocean for its development in multiple sectors.
