I was going to suggest Pharmacy Tech, actually. That's what I've been considering for the coming summer, as starting pay is generally 10 dollars an hour or better, the work isn't terrible, and really you don't have to deal with customers in any other way besides filing insurance stuff, running a register, and saying, "Let me ask the pharmacist." Of course, I have absolutely no idea how being a Pharmacy Tech in Canada works, what with their universal healthcare. You might get paid jack crap, or you might get paid more. No idea. Nor do I know the certification process. Here in the US anyone can send in for a license. All it takes is a background check and a couple hundred bucks. Then you just pay a few hundred more for the PTCB and, if you pass it, you're employable! Some places will even take you without PTCB certification.
Not a bad idea to look into something in the medical field, Natty-light. My dad once told me that if I got a job involving medicine, I'd be set for life. People are always sick and everyone dies, so there's always a need for more people in pretty much every field.
Cept X-Ray, MRI, and CT. That's one of those fields you get in and stay in because it's oodles of money for very little work.
