Like those migrants are going to pay for it. The first thing they do when they get to Canada is go on welfare. They are a net drain not a net gain.
this is a common misconception that we hear in the UK quite often. it generally comes from the low skilled/unemployed, due to the fact that the immigrants they tend to rub shoulders with are of a similar socioeconomic status as themselves. so they think all immigrants are like that.
immigrants to Canada actually tend to be better educated than the host population. same thing in the UK
"Immigrants More Educated than Canadians
On average immigrants are more educated upon arrival in Canada than their Canadian-born counterparts, according to the latest data released from last year’s National Household Survey.
The survey, which replaced the mandatory census used to obtain demographic data in previous years, found that although immigrants make up only about a quarter of the population, they hold approximately one-third of university degrees in the country."
