The challenge for the CPP—and I'm sure the banks and insurance people told you this—is that they don't really have mechanisms right now; they don't have the infrastructure to have an individual contribution type of thing. But barring that, I think that within reasonable limits, the more options the better.
So, no, we're pretty agnostic in terms of whether it's private, whether it's CPP, whether.... You don't want to be reinventing the wheel all the time, but no, in principle I think that's fine.
