I had 4 labs 1st year and they were the exact same ones you have and in the end it really wasn't that bad.
I hated physics in highschool, but I ended up taking Physics 1B03 and seriously it was one of my favourite courses, i even ended up taking 1BB3 this year!. If it's just the labs you're worried about, dont. Only because the labs aren't really labs, you go into the room sit down in a group and answer a bunch of questions in the lab notebook, maybe roll a cart here and there. That's really about it, plus the TA's (at least the ones I had) are REALLY helpful!
All I can say is that I wouldn't do 1L03, only because every last person I know who did take 1L03 (not exagerrating) took 1B03 either over the summer or in second year, so really it just seems like a waste of time especially if you took grade 12 physics.
If you plan on doing any honours program(4 years) you have to have a physics course by the end of your second year(I think), so yes you could go without physics in your first year.
I'm not a physics whiz, but I really do think people need to give physics another chance, it's really not as bad as you think
I would say an easy course to take would be latin, people may say it's a dead language but its one awesome course
Also, I know a number of people who enjoyed astronomy(but that may have just been because of the prof...(reid))
Here's the page where you can look at all of the requirements for specific second year programs:
