You could always take it early or late, the changes just shifted the penalties/bonuses for doing so. And those changes did not affect those already collecting.     

I mean, government could also tax your RRIFs at 90% tomorrow and leave you totally dependent on CPP. But is that a rational fear? No.  All efforts even being discussed towards CPP are for plussing it up, not down.  And even the increases are to be slowly phased in.
