Makes one wonder whether waiting beyond 60 to start CPP is a good idea if in fact benefits can be dialed back due to poor investment returns. It also means that if CPP investments are tanking so might your personal portfolio or pension plan.  Can you say eggs in one basket?

I'm not thinking CPP is likely to tank as bad as the personal porfolio in a downturn but I could sure see a means test for those who have taken care of themselves financially.  The spendthrifts may yet win the at the retirement game.  OAS and GIS have means tests, next stop CPP?
