The rapidly growing supply of university-educated workers from both immigration and domestic educational institutions, coupled with relatively slack demand for educated labour, has raised concerns about skill use in the Canadian economy. This study uses census data from 2001 to 2016 to compare trends in over-education among recent immigrants and Canadian-born youth. The study showed that only about one-half of the growth in university-educated workers over this 15-year period was matched with growth in jobs requiring a university education. University-educated recent immigrants became more concentrated in jobs requiring less than a university education. In comparison, Canadian-born youth with a university degree became less likely to work in jobs requiring high school or less education.
