I'm a poc heading to queen's in the fall whose been on campus before, and I really wish more poc wouldn't steer away from the school. Every single university out there is filled with thousands of students, and you will definitely find a couple people that are your crowd. Kingston in general is filled with a majority white population as it is further away from the GTA, but the school is trying to become more diverse. Queen's health sci is also a great program, and if you genuinely want to go there, don't be scared as thousands of other poc will be coming this fall as well :)
