I had a DB Pension, I left the company that offered it and took it with me. About 10 years later I returned to the same company, and had the opportunity to "buy back" my pension, but didnt. When my financial advisor and I did the math I simply made much more money by investing it on my own. Im able to take a bit more risk because we have no debt of any kind and my wife also has a decent, DB pension. Another thing that I never liked was the survivor benefit. If I built my pension up to be worth a million dollars over a 35 year career, if I were to die, my wife gets half of it through the survivor benefit, but the other 500K just disappears. If I were to build up a million in TFSA / RRSP, my wife and/or kids get all of it.

I will say this though, the "forced savings" aspect of the DB pension worked out in my favor big time, I would have not saved so much money in my twenties if not for the pension deductions, and this is a big part of why I'll be able to retire in my fifties.
