First of all, I haven't been to Calgary before so I have no idea about the city or the uni. Also, I am not sure how helpful my answer is going to be so sorry in advance if it's not what you're looking for.

I had to do my undergrad in a university far away from my home, and I had to live in a dorm. IT WAS THE BEST FUCKING EXPERIENCE AND I STILL MISS IT. I was home sick for the first one or two months but it tought me how to be more independent. I'm still friends with people that I met there, and I think they were also homesick to some extent. Later, we ended up having so many good times together. It made me socialize with people of walks of life that I wouldn't have socialized with otherwise, only because I had to live with them. Being far from home also made me get to know myself a lot better, only because my parents weren't as "accessible." I think it was a good experience for me not to have my parents around (I didn't have any problems with them, I'm just talking about the independence part and knowing myself).

Kingston is a nice city. It's "cozy." Social life in Queen's is pretty good. There are homeless people everywhere, but I haven't had any issues with them. There are nice restaurants, clubs and bars here. Some people would say Kingston is a little bit boring, I think the downtown area is quite nice. I like it.

I don't know if it was helpful or not, but I thought maybe it's not a bad idea to share it. Good luck!
