I think I'm fine with it.
From a public policy level, it probably means a couple hundred dollars a month extra per retiree when the time comes. Not life-changing, but if you're lower income that buys you better groceries, at least. I feel as though this increase is being talked about as being revolutionary, and it's not. If you didn't save for retirement (pension, RRSP, general assets/wealth) this change to CPP isn't going to single-handedly give you $50k a year in retirement. Not a boatload of extra money is getting paid into the plan, so not a boatload of extra money is getting paid out to retirees in the future.
As a few personal finance columnists have pointed out, this is, for most sub-45 yr old workers, the only defined-benefit, indexed, iron-clad pension they'll have access to. Increasing it a little is a good thing and acts as an enhanced safety net for retirees (I'm not optimistic that we can expect everyone to adequately save and invest for their retirements.)
From a personal standpoint, I'm pursuing ER and don't expect to be paying into CPP for decades more. Already, I'm looking at downshift options to give me better quality of life, so while I'll pay more in premiums I don't think the increase is terribly meaningful. I think DH is feeling a bit burnt by the raising of the maximum income level, but this is being phased in slowly so we may not have too many high-earning years left in the workforce by the time it's in place.
And in the end, policy makers don't care a fig what I think, so they'll make decisions and I'll just live with them. :)
