Colleges are generally vocational/applied (diploma or certificate granting) or university prep, for people who need to improve their grades/take some required courses before embarking on a degree program at a university. As far as I know, colleges cannot grant degrees (except for a few that are able to grant "applied degrees").

Universities, on the other hand, are academic focused and degree granting (either just bachelor or bachelor, masters, doctoral).

There are also University Colleges, but for a footnote you probably don't need to know about them. :)
