And their REPUTATIONS. This is by no means how it all is but this is the general outlook of each college and included is the general Hogwarts house representation as well.
The big four:
Trinity (Trin) aka “Slytherin” - pompous and proud is the reputation of this school. It’s also known to be very secluded and exclusive in the sense that trin kids generally hang out with other trin kids. A relatively small school in terms of the number of people. Trin is known for having the poli-sci, IR (International Relations) and other pre-law related studies and students for the most part. Very competitive. And the hardest to get into. It has to be your first choice and there’s a grade requirement. Which is why many trin students may have an air of superiority to them. They are considered to party hard though it may be hard to find someone to get you in.
It is one of the prettier colleges with a very exquisite quad though it has a bit of a colder and more formal feel to it.
It is said to have mostly girls and gay guys. Gay guys being = lots of hipsters. It’s a hipster mecca. (And many turn out to be gay)
Victoria (Vic) aka “Ravenclaw” - the pride and glory of UofT. All the best (or rather the more known) people come from Vic. Vic is generally a humanities campus and has many humanties students. Many people at vic are english orientated because it has a great english program.
Vic people also end up generally hanging out with other Vic people because students get caught up in the bubble especially if they live on campus.
It is one of the prettiest colleges on campus with old architecture, the beautiful Isabel Bader theatre and lovely open quad that is redone every year to be green after the winter has dried out the nature. You can see many students lounging about, playing or even dogs running around here.
This is another big hipster center. A roughly 75% girl filled college, Vic is known to have the pretty ladies. It is a generally mixed-ish school with mostly white people.
University (UC) aka “Gryffindor” - UC is a large college right in the center of campus. It’s a party hub and generally has a mix of people and programs. It has one of the most amount of students. UC is considered a friendly-ish school because of the larger amount of people so a variety of people from other colleges may socialize here. And is also supposedly has good-looking guys.
The rest are the “Hufflepuffs”
St. Michael’s (St Mike’s) - Known for being a Christian and heavily Italian-filled school, it is also known as a party school. Probably the party school. This is where you find the club nights and the skeezy parties.
And the rest:
Woodsworth - A relatively small college. A big program for this college is Criminology. It is known to have the nicest residences to live in. Little is known about this college.
Innis - Another small school. They generally have their pub nights at a Fox and the Fiddle on Wellesley Ave. It’s a small community type school. One of the smallest schools and student body on campus. Not known for having the good-looking guys. Girl status: unknown.
New - New is named so because it is a relatively new college. This college is mostly filled with the asian variety of students. New students are stereotyped as mostly phys-ed kids. As they have their own gym and are located right next to the Athletic Center (the AC). New is fairly new and not considered the better looking of the colleges, having very modern and box-like structures. This would also be where many of the life science kids are also located.
This is by no means a specific interpretation. Many fields of students are spread out over each of the colleges. Specific colleges may have more specific fields but for the most part, many of the science, engineer, humanites, commerce students are spread out in which college they decide to be part of or associated with.
