The December 2008 issue of Statistics Canada’s Perspectives on Labour and Income features an article on the labour market experiences of established and recent immigrants to Canada. The abstract:
During the 1991 to 2006 period, the proportion of immigrants with a university degree in jobs with low educational requirements increased, not only among recent immigrants but also among established ones. The increases for established immigrants suggest that the difficulties, which have long plagued recent immigrants, are not necessarily temporary. Changes in the profile of established immigrants—particularly language and country of origin—accounted for only a quarter of the deterioration for established immigrants.
