Oh HHM, I truly empathize with you. Two years ago I was out of work due to a disability. Before I was approved for social security benefits, things got so bad that a dear friend gave me three boxes of groceries for a Christmas present. Not great for the pride, but circumstances sometimes kick you in the ass and make pride a luxury one can’t afford. Actually, my friend’s generosity – knowing someone cared – gave me hope for the future and lifted my spirits. Much as the Dopers here have done for you. 
If I weren’t still struggling now, I’d happily chip in without a second’s thought. I know you’ve been the recipient of some wonderful generosity and I hope your PayPal account comes through for you in a hurry. But if it doesn’t, I wanted to second a recommendation offered earlier.
It’s a last resort, but sometimes desperate times call for desperate measurers. I’m talking about applying for a payday advance / cash advance loan. There are several available in Canada. You can do a search on Yahoo.ca or Google and you’ll find skillions of 'em.
The positives: a) They pay you overnight, and b) they don’t do credit checks. (Trust me, I had utterly craptastic credit when I received a loan!) As long as you haven’t defaulted on another payday loan or have a kabillion overdrafts on your bank account, you’ll probably be accepted. Also, the income requirements I’ve seen were pretty low, usually anywhere from $900 to $1200 per month (U.S. dollars).
You usually need to have been employed (or receiving benefits) for at least three months, be over 19, have a driver’s license or some other form of ID, and a current bank statement. While most firms require that you have direct deposit for your paychecks, you can find some that don’t.
The (very significant) downsides: The interest is close to usury; a $100 loan here in the U.S. will usually cost $120 - $135. And woe be unto you if you don’t have the money in the bank when the loan is due, 'cause payday loan firms make it waaaaaaaay too easy to refinance. That’s where they get their profits: we’re talking 700% interest plus a refinancing fee.
I know people who got in even worse financial trouble than when they started by rolling over loans a couple of times, borrowing from one payday place to pay back another … ugh. The interest really snowballs if you refinance, and you can find yourself paying $250 interest on a $300 loan after only a few weeks.
So to sum up, if you are absolutely certain you’ll have the money in the bank when the loan comes due, and you are strict about not refinancing (i.e. postponing) the loan … it may be worth $135 later to have $100 you desperately need now.
Again, if you can get a loan from anyone you know or get by some other way, avoid this solution. But as a last resort, one-time fix to an emergency situation, it’s good to know there’s at least some option available.
(BTW as far as fault goes? It doesn’t matter. When someone is hungry it’s not for us to judge how s/he got into that position; the most important thing is to get the person fed.)
Best of luck to you, HHM, and bravo to all the Dopers who proved yet again that the interweb ain’t such a bad place.
