The article talks specifically about immigrant tech workers and the impact of different immigration rules between both countries on the tech job market. Salaries in some parts of the US is much larger than in Canada, nobody is arguing about that, but it's easier for a tech company to hire an immigrant in Canada. In a nutshell, the author pushes the idea that the US current immigration policy gives a disadvantage to the US tech industry, especially for startups. It seems like an oversimplification, because immigrating in Canada is not so simple, especially when accounting for the differences between provinces (I've heard that Quebec is a bit paradoxical about immigrants).
