Hi again Matt - I take it you don't have a GP (general practitioner/family doctor) in Canada yet? There are a number of websites that can help you find a doctor. I found one that looked fairly trustworthy:

http://www.ratemds.com/I'm sorry I don't really know much about available surgeons in St Catherines or Toronto. Your GP should be able to help you out with that. You can also go to the website for the Ontario College of Physicians and Surgeons to look for the specialist you need.
http://www.cpso.on.ca/docsearch/They have a doctor search and you can find records and contact information. Your GP will likely refer you to a surgeon s/he knows and who is in your 'catchment area'. If you are not happy with your GP's choice, you can also find you own surgeon outsided your catchment area, by using the Ontario College of Physicians and Surgeons website. You can then call the offices you find to ask about wait times, and then ask your GP to refer you to the surgeon you found for yourself. (I had to do that a few years ago for another medical issue - the surgeon my GP referred me to wouldn't be able to see me for almost two years so I found another surgeon who was able to see me in one month - it just took some research.) Just to give you a heads-up: getting to see a specialist for this kind of problem can take a LONG time, so definitely make sure your GP understands how the AF is affecting the rest of your health and your quality of life. Docs tend to underestimate how life-altering AFs are.
I had a colonoscopy done when I had my fissure and I was very surprised that it didn't hurt at all. The prep didn't cause problems with the fissure. That's mostly because it's mostly liquid that comes out, and it doesn't even sting much (maybe the drink alters the ph of the stool?). The procedure itself wasn't painful because I was put under sedation. It also didn't make the fissure worse. So don't worry about the colonoscopy - many folks here have had a colonoscopy with a fissure and it was not nearly as bad as they expected it to be. The worst part really is drinking down that awful solution that makes you poo. The trick there is to keep it on ice and make it as cold as possible, then it doesn't taste so bad.
Good luck with everything - I hope you get to a specialist very soon! :D
