All right. I'm going to answer you in English because of the complex nature of the act.
You could have a circumstance, for example, where a person is living outside of Canada. I don't want to get too bureaucratic. In 1977 rules were changed to introduce partial pensions. But there are people who could perhaps be living outside of Canada, and they would qualify under these older rules that exist for an old age security benefit. And I can follow up with that later, but if they decide to move back to Canada two months after they've applied and they come to realize that they could have had a higher benefit, they would want to withdraw it.
