This is an Irish forum, so I doubt you'll the best possible advice. I'll try throwing my two cents in anyway. Your situation looks so serious, I think you need all the help you can get!
As I understand an RRSP, cashing out a part of that should be an absolute last resort as you will be liable for tax clawback.
As for income, have you not being paying into Employment Insurance? If so, then you should be able to get some assistance relative to the proportion of time you've been paying it.
Personally, I think your fianances look so bleak that you really need to look at selling your property, extracting the equity and using that to pay off your huge amount of personal debt.
When you get out of this situation, I think an important lesson to learn is that you really need to have a contingency fund of at least three months pay to allow for a crisis.
