In Canada, "college" is quite often used to refer to a school past high school that usually offers vocational education. "University" is the term used for those attending higher education schools in other fields.
ie: You go to "college" to learn a trade
you go to "university" to study psychology, premedicine, or pharmacy
LOL. I actually did not know that about Canada. But, my family has some friends from Great Britain (I think?), and they say they go to "university"...in the context that you mentioned (eg. with pharmacy). Kinda like they call their apartments "flats" and so forth. I guess maybe I was being egocentric (maybe?) and only considering the terms used in the states.
With undergrad colleges and universities:
Universities have a Grad school program
We had a problem at home with this with a subsididary of the University of VA. There was a branch that they refused to call University of VA-Wise b/c it had no grad school.
It is The UVA- College at wise.
Perhaps most of the COPs didn't have PhD programs when they began so they were "Colleges" and the others who offered the advanced degrees were termed univeristies
