In some ways though closer to the US, we're still kind of in between the American-style culture of breadth and the British-style culture of specialization for universities -- for example, many American students can come in with an "undecided" status in their first year or even later, taking some time to decide their major, while I think this is possible in Canadian, or at least some Ontario universities too, I think it's far less common. Having many Gen Eds as requirements for students aside from the courses needed for their majors do exist here, but are less of a deal than stateside. And of course, it's well-known that the US has many more non-grade or non-academic criteria to get into university to begin with -- eg. not just grades and the SAT, but essays, extra-curricular things, volunteer work done in high school etc. I notice Canadians don't really have to stress as much and plan really far ahead about applying for college/university than Americans generally -- the "helicopter" parent also seems to be more a US thing too.
Also, some aspects of US college culture -- for example, fraternities and sororities, "college towns", college sports, etc. seem less prominent north of the border, though probably still more present, than in the UK where it barely exists if at all. Then again McMaster University was one of the schools that was partially an inspiration for the movie Animal House, which is one of the archetypal depictions of American college culture in film.
