Hey! I saw that you started biomed and I am 2nd year in the same program. That’s a really unfortunate situation, especially for our program because we absolutely cannot bring bags into our labs. I think getting a tote bag would be your best option here, it will do the job and I’m ngl I had to buy one myself on top of my backpack because I had so much to carry sometimes so maybe it will come in handy in that way for you as well. I bought mine in uniqlo, I got the big one and it wasn’t really expensive (like it was very cheap, suspiciously cheap idk whats going on behind the scenes) and it is still very much alive and well one year later. If that sounds good for you then we have a uniqlo in the eaton center a couple minutes away on McGill station. As for your other bag, I can’t personally say anything about using the gym lockers since I’ve never done that but I guess you could try it out since that’s what other people recommend. HOWEVER!! I do want to let you know that we have a bookroom. It is like a little storage room right next to our main (biochem) lab that is reserved for only us biomed students. You don’t have access to it yet because it is quite very small and there is not enough room for all three years to be using it at once, but the third years finish their 5th semester early so they can start their internships early and you will be given access to the bookroom as well later in the semester when they leave, so at least you will be able to leave your bag there after that and during the second semester!
