Summary: First, what is the Canadian Pension Plan (CPP)? It's roughly 5% of your salary, up to a maximum of roughly 57-58 grand – however, these numbers may change annually. Old age security (OAS) is a dollar figure that you get when you hit 65. It's based on how many years you've been a resident of Canada regardless of whether you paid into it or not, unless you made too much money in which case the OAS will be clawed back.
