The "nerds" Indians do not live in Calgary. They live in Toronto and Vancouver. Better they live in Calif, Washington and parts of Texas.
That being said, once you get settled in, most of the time you do not have to deal with this mess. Given that Calgary has more houses looking for people, you will be able to pick where you want to live.
Now if you are looking at dating scene, I do not now how that will go.
Honestly I liked the city, didn't like the weather as it is variable, yesterday I went to their library, that library is amazing, the only library that I seen better than that is library of congress.
You can't even compare houston library with calgary the architecture it self is beautiful, it is small but the facilities they offer is simply amazing. The only thing I didn't like there is a bradder working in the customer service (Anil) ,that dude was rude ,I am not surprised though. He was talking to me like he is my prof or my dad ,moron.
Found a room and a bathroom for 550$ ,really loved the place, toronto I just don't like it it is too crowded, Vancouver also.
