Canon is located in town, over by the Calgary Sun building (2828 16 Street NE). If it is no longer under warranty, I suggest Alta Camera Service.
Iggypop - it sounds like you have lens error. Unfortunately, that's something you'll have to get repaired. Does it say anything on the screen when you power up? (eg. E error?)
Camera repair costs are through the roof. It's generally not the parts, but the labour. Most bills come out to around $100. With cameras dropping in price, it's not worth repairing. You can take that $100 and invest it into something new that has the latest technology. Some of Canon's new line has been announced. For something similar to yours, I'd look at the SD1100 (

Claeren - I remember that a lot of the S1 cameras were prone to that problem back in the day. I believe it was circut issue. Have you tried using the viewfinder to take any photos? Turn the screen off and try just using the viewfinder.
