Congrats on your financial accomplishments so far. Unlike US taxpayers who can deduct mortgage interest on a principal residence, it is almost always better for a Canuck to accelerate paying out the mortgage.
I trust you and your DH have been maximizing your contributions to RRSPs. Despite the new ITA provisions permitting splitting of qualified pension income, it is still good to utilize the Spousal RRSP option. What Jimmy has given, Stephane (or his successor) could always take away at a later date.
You may also wish to consider the Canadian based Financial Webring
forum as a source of Canuck oriented info if you have not already found it.
