For a number of very important reasons. They're important for the individual to be able to have access to the benefits in Canada that would have been provided by another country, and vice versa. In that respect, because of the nature of the very important immigration in Canada, there is a lot more inflow, if you like, of pension moneys in the country than outflows. That's number one. There's an aspect of reciprocity of treatment in that.
The other thing is that it's also an economic argument. When we enter into such an agreement with a country for Canadian businesses doing business in that country, the Canadian expatriates who are there working temporarily are exempt from the local social security tax. They continue paying their CPP and accruing benefits here, but they're working in some other country.
So we have 52 agreements that are signed—50 are in place and implemented—and we are very busy negotiating at this time with India, Brazil, Argentina, etc.
