Yes, Mr. Chair, we've been looking into this, prompted by the Auditor General, and there are two studies that have come to our attention.
The first was done roughly a year ago by the OECD, and it estimated that the number of Canadians living outside Canada--Canadians born in Canada who are living outside Canada in an OECD country--was roughly 1.5 million people, but that is only in OECD countries. There were concerns about the methodology, which the authors were only too happy to express, but it was an estimate.
A more recent piece of work by the Asia Pacific Foundation tells us that their estimate, based on Statistics Canada information, is something like 2.8 million people living outside Canada. So it tells us that an awful lot of Canadians are currently not in the country. They may come back, they may not.
We need to think about the risks that poses for our social programs and the risks it poses for the integrity of the SIR and take action in the way the Auditor General has described. We need to be consistent in how we deal with the dormant flag. It needs to work in all programs like it does in EI, and if it doesn't, then we have to have some control that mitigates that same risk.
