The TIFF website went live sometime last week and is chock full of useful, necessary information. If you haven't gone, get thee hence, immediately.
Last year, I found the most important sections to be the news releases and the box-office. The first will keep you abreast of the latest film announcements, while the second lets you know exactly how badly you're gonna get screwed by the festival.
The whole thing is invaluable, so give it a go. I'll wait for ya.
