What strikes me immediately is that going forward:
1. Because of your wife's lower income, she should open a high interest savings account and put all her income into that account for the house purchase.
2. You should have a separate account from which to pay all the expenses from your (higher) income.
3. If you are going to contribute to an RRSP, it should be spousal so that you get the tax deduction but your wife will be able to withdraw at her (presumably lower) tax rate after at least 3 years.
It is the 102K in the open account that needs to be looked at. If you check the tax slips from the last few years, you should be able to see what your after-tax return really is. Forget about the history of this account, and try to determine if you are better off holding these funds for a few more years, or buy your house sooner rather than later. No point in looking for another investment firm if you are going to liquidate the funds anyway to put towards your house.
