The country's government plans to welcome 500,000 immigrants each year. This means that Canada's population is expected to grow by 1.5 million people over the next three years.

Canada has high hopes for immigration to fill a gap in the economy created by the departure of a huge number of aging workers from the labour market, but not everyone agrees on attracting that many immigrants.

Earlier this month, the federal government announced an ambitious plan to welcome 500,000 immigrants by 2025, with nearly 1.5 million new immigrants coming into the country over the next three years.

Why Canada needs migrants 

Last year, the country welcomed 405,000 permanent residents - the most in its history.

The reasons lie, to some extent, in simple maths. Like many Western countries, Canada has an aging population with a low birth rate. This means that if the country wants to grow, it needs immigrants. Immigration already accounts for almost all of the country's labour force growth, and by 2032, it is expected to account for all of the country's population growth, according to a government press release. 

Canadian authorities are welcoming 1.5 million immigrants into the country. With an unprecedented wave of newcomers, the Canadian government hopes to fill a labour gap in the Canadian economy worsened by an aging population and a mass retirement of the baby boomer generation. That means that the average age of residents is rising steadily, threatening to turn Canada into a nation of pensioners that the working-age population will find it increasingly difficult to support.

Incentives for migrants to Canada 

That number of migrants per capita is about eight times more than the UK plans to accept, and four times more than the US administration expects to settle in.

Canada has been deliberately encouraging immigration for decades to keep its population and economy growing. Immigrants are granted permanent residency in Canada but not citizenship.

The state of Canada's migrants compared to other countries 

If a country wants to grow and develop its economy, it cannot do without immigrants. The growth of labour force in Canada is already almost entirely due to immigration, and by 2032, the government predicts, the same will be true for the population as a whole.

Today, almost one in four residents of Canada is from another country. In all other G7 countries (i.e. the developed countries of the G7), the figure is lower. Take the United States, which is considered the world's centre of cultural intermingling: only 14 per cent of the population is immigrant. The figure is roughly the same in Britain.

Challenges of migration to Canada 

In Canada, support for immigration has historically been high. But that does not mean there are no worries about the influx of immigrants. Illegal crossings of the Canadian border from the US have increased in recent years, and the emergence in 2018 of the People's Party of Canada, a populist party with extreme right-wing views, has kept talk on the subject alive ahead of the 2019 parliamentary elections.

When the country's government announced plans to accept up to 500,000 migrants a year, the autonomous province of Quebec, which can set its own quotas on immigrant inflows, said it would agree to accept no more than 50,000 people. That means Quebec, where almost a quarter of Canada's population lives, is willing to accept only 10 percent of the intended arrivals.

Canada has tried to attract immigrants by promising permanent residency, which gives immigrants, who have the right to remain in the country indefinitely but are not citizens, to support population and economic growth.

This plan to attract immigrants to the country would allow Canada to take in about eight times as many permanent residents a year. That's four times more than in the United States.

But among the need for more people at work are growing problems. Large cities like Toronto and Vancouver, where about 10 percent of the population currently lives, have affordable housing crises.
