Funny story. But apparently nobody taught you nuttin about canoeing 
First, tie everything to the canoe except yourself, passengers, and the paddles. *duh* 
Second, the way to empty a filled canoe when you can't stand up is to get it upright, and then go to the very end. Front or back doesn't matter unless you have a canoe with a flat chopped stern, in which case use the stern. Try to climb up onto the end, pushing it as low as possible. This will let the far end climb up out of the water. Yea all the water ends up running out of your canoe right into your face, but you can get at least half to two thirds of the water out with this method.
That's also how you climb back in... Over the end instead of over the side. If you can't do this, you're too fat and should exercise more 
Keep one extra lightweight paddle securely tied or clipped somewhere inside the canoe.
If you require glasses to see, use a strap to keep them on your head when you go overboard, otherwise you are more likely to find yourself out in the water and not able to see well enough to save yourself.
I've used these techniques many times on boy scout canoe trips and it all works like a champ.
Also, life jackets... pretty much mandatory for everyone, all the time. One slip and a bump on the head against the boat/canoe/rocks and even an expert swimmer is headed for the bottom. Spend a little bit of money on ones that fit well and you won't mind them so much.
Thanks everyone for the comments
LOL Obviously you have never tried that technique on my canoe.
Remember this is a 17' coleman plastic canoe. not aluminum or fiberglass.
Empty this thing weighs quite a bit
Actually I did try that. the arse end went downa little but the bow didnt raise enough to get any water out. This sombish was FILLED.
And then I was too tired from trying to swim upstream to try to climb up onto anything.
I had often thought about teathering the things to the canoe.
but my primary concern was that in the event such an instance happened as it did. Someone might inadvertantly get tangled up in the teather.
Which in a set of rapids wouldnt not be a good thing.
In hindsight. Looking back at this particular set of rapids. And the way the canoe rolled out from underneith us. I am still convinced I was better off without having any kinds of lines for anyone to get caught up in.
The mistake I made as far as my gear is concerned was not placing my new pole under the crossmembers as I normally do.
Instead it was still standing partially upright leaning against the side.
Mistake #2 was in wearing cutoff jeans and a that were cut a bit longer for style (literally a hair above the knee) then for movement when wet. and a T-shirt.
Both I found provided added resistance to and partially restricted my movements trying to swim.
Mistake #3 was in trying to swim after my tacklebox while still in a fast current. Particulalrly in light of mistake #2.
I got tired.. real tired. and in a hurry too
