Canada uses a point system to select immigrants likely to contribute economically to Canada, ensuring that most newcomers are young, speak English or French, and are well-educated- 45 percent of adults arriving in 2000 had university degrees. However a quarter of the recent immigrants with a university degree are working at jobs that require only a high school diploma or less, and only half are working in Canadian jobs that use their credentials three years after arrival.
