Yes - unfortunately many have failed in past years and yes, it tends to be difficult to get a place. The spots are snapped up extremely quickly (last year there were three rounds and each took less than 1/2 hour to cap). The most you can do is keep checking the web site regularly and make sure you are at your computer when the program is opened so that you can apply immediately. CIC has changed the rules somewhat this year so this may mean that spots don't go quite as quickly. Having said that, you should be ready to apply immediately when the program opens.
