It's all supply and demand and changes from year to year, I know a small number of people who dropped out of eng, but I believe they either switched into B-tech or math and stats. The only programs that anyone I know didn't get accepted to were management and biomedical unless they ended up dropping a course to do it over the summer.
Just figure out if its what you love to do from the get go, if you have zero motivation to do anything in first year, I don't think it'll get much better and you're just wasting your time. You'll get higher grades if you end up doing what you love. That being said, I wasn't a fan of first year but getting into my desired second year program is getting me really excited to go back in september.
With all that being said, if you don't make it into your first choice program at the end of the year try not to freak out. Just stay positive and work hard, theres always a chance that you could switch into the program of your choose (with high enough grades) or it may turn out that you love the program you got put into regardless.
Good luck in September!
