Your SSN won't be valid, but the bank doesn't know that and neither does the IRS, it only really matters for employment purposes.
The main thing you need to do is tell the bank you no longer live in the US and ask them for a W-8BEN form so they don't report any interest paid on your account to the IRS.
Bear in mind if you keep the property you will become subject to US capital gains tax on it. I'm assuming you've been filing 1040s and not 1040NR tax returns so when you move your tax home back to Canada (there is a lot of paperwork to do that) you will cease to benefit from the CGT exemption US residents get.
I think the current limit for CGT for non-residents is $32,000 (or rather it's 0% up to that limit), but check if it's a major issue for you. I'm not quite sure how the US works if it you've become non-resident, whether you benefit from the exemption up until the point that you moved or whether you can only claim the non-resident limit at the point you sell it.
