Once in Canada, many skilled immigrants, particularly those with Indian, Caribbean, Chinese or Arab backgrounds, wind up in occupations far below their educational levels—despite having been selected for high levels of training and experience in professions such as health care, engineering and education. The problem is known as "brain waste" and some economists estimate its cost to Canada as totalling at least $3 billion a year, not to mention the ruined dreams suffered by the immigrants themselves.
