We do keep those statistics, as a matter of fact. In fact, we have recently published a study on the interprovincial mobility of immigrants in Canada. We looked at immigrants who landed from 2000 to 2006, based on the 2006 tax year. What we found was that immigrants move from some provinces more than others. Ontario retains a large number of immigrants. About 91% of the immigrants who come to Ontario stay in Ontario. The Atlantic provinces have a much lower retention rate. There are differences based on whether immigrants are family class or business investors. In addition, we found an east-west shift. So the net beneficiaries of that migration are actually Alberta and British Columbia. Those were the provinces that had a net increase overall.
