I can answer that. What was put in place in fact is something that provides more flexibility to people. Before of course OAS was available when you reached 65 years old.
The deferral will allow you, if you choose to do so, to defer it as long as you wish, up to age 70. A calculation is done based on actuarial costs, which means you will increase in fact by 7.2% each year you defer the amount of your benefit for the rest of your life.
It adds flexibility so that if someone decides to keep working, for example, to remain in the labour market past 65, they can decide to postpone the receipt of OAS without losing any money. In a way, because of the actuarial calculation, over the period of time they will receive the same amount without losing anything.
So that adds a lot of flexibility, and of course it's related to the fact that the labour market is evolving with the demographic challenges society is facing. People are aging, and we know that if people are extending their participation in the labour market, that will also help the entire country to deal with some of the pressure we might be facing. So it's to have that flexibility, and it's an additional choice for people.
