I think the whole premise of the proposed transaction is misleading or flawed.  The dilemma is predicated on the fact that tax deferred or exempt accounts preclude you from benefiting from tax loss selling.  However, there is nothing about the strategy that allows you to recoup that benefit.  All it does is provide the investor with the necessary funds to repurchase the stock in a cash account.  The fact that any future gains will benefit from preferential capital gains taxation doesn't change anything.   You still can't apply the loss against capital gains.

The only thing you have really done is chosen to pay tax today on the full value of your RRSP withdrawal on the premise that you will ultimately save taxes on a future capital gain.  Which in my opinion serves to add tax risk onto an investment that already seems to be elevating your total risk profile.  And that doesn't even begin to consider speculation on changes to the tax code in future years could factor in.
