 The 2003 study explains that the low-income rate among non-immigrants declined in the 1990s, but this was more than offset by the income profile of new immigrants, resulting in a net rise in Canada's total low-income rate.An updated January 2007 study by Statistics Canada, explains that the deterioration continued into the next decade, with the low-income rate of recent immigrants reaching rates of 3.5 times that of Canadian born in 2002 and 2003, before edging back to 3.2 times in 2004.The 2007 study explains that this deterioration has occurred even though Canada implemented changes in 1993 to encourage more highly educated immigrants, with 45% of new immigrants having university degrees as of 2004.
