A new study done by the Fraser Institute shows the fiscal burden imposed on Canadians from its high immigration rate is now up to $30 billion per year. That is because immigrants have lower wages and thus pay less tax than other Canadians, while making use of more government resources. They also have a higher unemployment rate and, on average, more children, so receive more in benefits.
Estimating the fiscal burden immigrants impose on Canadians requires data on the average taxes paid and government benefits received by immigrants. Data from the 2016 Census also cited by Gatehouse shows that the average income of recent immigrants aged 25-54 continues to fall short of that of non-immigrants, which means they continue to pay less in taxes on average.
In our most recent study we used basic statistics from the previous census and the National Household Survey to estimate that because of Canada’s progressive income tax system, recent immigrants paid much lower income taxes than non-immigrants. We added to this amount other taxes related to income and wealth, such as the GST and capital gains taxes, and concluded that in 2008-09, recent immigrants on average paid $13,100 in tax compared with $18,000 paid by other Canadians, yielding a shortfall of $4,900 per year.
