Yes, and the government has introduced, with the agreement of the provinces, what we call the post-retirement benefit. In 2012, the work cessation test was removed from the Canada Pension Plan. Therefore, all Canadians have the choice and the flexibility between retirement income and working earnings. If they ask for their CPP benefit, they are free to do so. If they continue to work, they contribute, and there's a post-retirement benefit that is helping them increase their benefits if they continue to work after they ask for their CPP benefits.
