You need to think as if you were a VO, then try to answer these questons by yourself.
1) Just say travling. You'd better select a target to travel, and do a little bit of homework about it. At least you should know where it is and why you want to go there. Do tell me you wanna go to mid-west to see the cows and the corns, it doesn't work.
2) It'd be better you have some financial statement. The key to B visa is your tie with Canada and, if you are self-sustained. If you say you are a student but you couldn't provide any proof how can you pay for your tuition and living, it looks bad. It doesn't sound like you are traveling in US, but like you are going to work without authorization.
3) Again, any means can show you have good/strong tie with Canada will be positive to your case.
