Thanks for the advice. My pension will probably be 60% maximum because I started with the public service only a couple of years ago and don't plan to work into my 60s.
I've considered my options with regard to TFSA vs. RRSP. I should be able to max out both of them in future years, so I'm considering holding mostly XIC in my TFSA and all of my US/international equity in my RRSP.
By the way, I understand from CC's post here that Canadian ETFs that simply hold US ETFs have an additional drag due to withholding tax on dividends, but what about foreign exchange every time (likely once a year) I purchase additional units of Vanguard ETFs? Couldn't that add up to more than the withholding tax drag?
