It's a great question. To even know how much you're going to receive from CPP, you have to go on Service Canada and create a log-in to get your CPP statement. It's not something that's automatically sent to Canadians every year. We automatically see our deductions from our paycheques every two weeks, so we're aware of what's going in, but as you say, we're not aware of what will go out.
Typically, in a workplace pension plan, the plan administrator would have to provide an annual pension statement to every member saying this is how much you've put in, this is the amount in benefits you've earned to date, and this is your expected pension on retirement. I think it would be entirely appropriate for the CPP to do something similar so that we don't only see what's going out every two weeks, so we can prepare for what we will receive under the plan when we retire.
