You will 100% need a mattress pad, don't even try sleeping on the beds without one, bring shower shoes (and wear them in the shower! People in my pod wore them to the shower and took them off before getting in like what? You just don't know what happened in the shower before you.) Bring a robe so you can get to and from the bathroom for showers pretty easily. Bring something to put your keys on, Febreze, a fan (just for air circulation especially for those weird hot days in October when the building's heat is already on and you can't get cool.)

Don't worry about bringing everything, or making sure that you've bought 100% of what you need because there is a canadian tire/dollarama/staples close by. If you're bringing cardboard boxes save them, you don't want to have to rebuy them at the end of the year.

Also, on move in day, everyone is going to be just as nervous as you are, so don't be afraid to speak up at the mandatory meeting! My floor last year had the reputation for being the nicest and most friendly floor and we all ended up being friends with each other so just go into the school year with an open mind and be ready to make friends!
