OAS (Old Age Security)
A government retirement benefit based on years of Canadian residency, not employment history.

What it means
Old Age Security is a monthly government benefit available to most Canadians 65 and older, based on how many years you've lived in Canada as an adult — not on whether or how much you worked.
Why it matters
Unlike CPP, you don't need a work history to qualify, which makes it especially relevant for newcomers and anyone with a non-traditional employment history.
Common misunderstandings
- Higher-income retirees can have some or all of their OAS "clawed back" through a recovery tax — it isn't guaranteed at the full amount for everyone.
- It's not automatic in every case; enrollment sometimes requires an application.
Where you'll see it
In retirement income planning, alongside CPP and personal savings.
