RE: TFSA'sPOA and beneficiary..You have done the paperwork.....Its still their money and I would make sure you are the sole beneficiaries of the TFSA accounts.If other siblings involved it can get messy regardless of their wishes.Once someone dies and money is involved what you think is easy and simple changes...I have seen the scenario a few times and just giving you another avenue to look at.Still gray area with CRA actually giving money to them
