As Michel started to introduce, there's the base CPP and the additional CPP. The base CPP is the plan that has been around since the 1960s. It was always designed to be one of the three legs of the stool for Canadian retirement, along with workplace pensions and savings. With workplace pensions moving away from defined benefits to defined contribution, the CPP is increasingly important. That's part of the rationale for moving to the additional CPP.
Going forward, I personally believe that the CPP's relevance for retirement in the decades to come will only increase with the additional CPP. It's one of the reasons we are really trying to continue to educate on what the CPP provides and its importance in decades to come to the retirement of Canadians.
Maybe, Michel, you would like to add something.
