Elephant seals spend the majority of their life (90%) underwater in search of food, and can cover 100 kilometres (60 miles) a day when they head out to sea. [11] When elephant seals are born, they can weigh up to 36 kilograms (79 pounds) and reach lengths up to 122 cm (4 ft 0 in). [11]
The table below lists the 100 largest census subdivisions (municipalities or municipal equivalents) in Canada by population, using data from the 2021 Canadian census for census subdivisions. [1] This list includes only the population within a census subdivision's boundaries as defined at the time of the census.
The northern elephant seal population was estimated to be 171,000 in 2005. [1] Beginning in the 18th century, northern elephant seals were hunted extensively, almost to extinction by the end of the 19th century, being prized for oil made from their blubber, and the population may have fallen as low as only 20-40 individuals.

Southern elephant seal harem on a beach on the Kerguelen Islands. Southern elephant seal world population was estimated at 650,000 in the mid-1990s, [1] and was estimated in 2005 at between 664,000 and 740,000. [18] Studies have shown the existence of three geographic subpopulations, one in each of the three oceans.
The large size of Canada's north, which is currently not arable, and thus cannot support large human populations, significantly lowers the country's carrying capacity. In 2021, the population density of Canada was 4.2 people per square kilometre.
The main driver of population growth is immigration, [8] [9] with 6.2% of the country's population being made up of temporary residents as of 2023, [10] or about 2.5 million people. [11] Between 2011 and May 2016, Canada's population grew by 1.7 million people, with immigrants accounting for two-thirds of the increase. [12]
Canada population density map (2014). A population centre, in the context of a Canadian census, is a populated place, or a cluster of interrelated populated places, which meets the demographic characteristics of an urban area, having a population of at least 1,000 people and a population density of no fewer than 400 people per square km 2.
The territories (the Northwest Territories, Nunavut, and Yukon) account for over a third of Canada's area but are home to only 0.32 percent of its population, which skews the national population density value. Canada's population grew by 5.24 percent between the 2016 and 2021 censuses. [1]
