Here's an interesting study from U.Ottawa in 2010: http://sciencessociales.uottawa.ca/grei-rgei/fra/documents/W...
Of interest: 1986-2010 only 130,000 individuals gained citizenship via the immigrant investor program. Of those about 32,000 were the primary applicant, and 97,000 were family members (on average 3... so wife + 2 kids).
This bit is also pretty telling:
> Contrary to popular belief, a majority of respondents (82%) reside in Canada on average between 10 and 12 months a year (Table 4). In addition, another 11% of respondents indicated that they stay in Canada for 7 to 9 months a year. The only official and comparable figures on this topic come from the province of Quebec, where about half of all immigrant investors who landed in Canada since 2003 still lived in the country in 2007 (Figure 12). Our survey results give a higher estimate on a national basis of the proportion of immigrant investors who reside permanently in Canada compared with statistics from the province of Quebec
Trusting the Conservatives to tell the truth about immigration issues is foolish. The minister's comments are directly refuted by this study. Especially his "or making a positive economic impact"... here's a quote from the start of the study:
> The Program clearly constitutes a positive economic initiative for Canada. Considering that about 2,500 immigrant investor families enter Canada each year, this means that the Program provides an annual economic contribution of $1.9 to $2 billion to the Canadian economy
