The tax-free savings accounts you are referring to are not taken into account for purposes of the pension division rules. They would, under provincial property law, be taken into account for purposes of determining the family assets subject to division.
What's interesting about the tax-free savings accounts is that they can be helpful for lower-income people saving. It's not a really good idea for very low-income people or people who don't have a taxable income to be contributing to an RRSP, because RRSPs become effective only if your income is, say, above $40,000 or $50,000. The TFSA can provide a helpful retirement savings vehicle for people who have lower income if they have money to save--which is, of course, a big “if”.
