If you look at the average benefits for someone who retires at age 65 and has contributed their entire life, before the recent reforms, they would have received the equivalent of 25% of their pre-retirement income. With a lot of study, including after the global financial crisis, it became clear that Canadians were not necessarily investing sufficiently in their RRSPs, because they're living longer lives, or that they did not have access to a workplace pension, so the reforms marginally increased the contribution rate. However, when they retire now, the replacement is not 25% but 33%.
It's elegant, because if you save at home, you save at work and you save through the CPP, with the three pillars equal at 33%, you retire with almost 100% of your pre-retirement income—again, on average.
