Yeah, I'm Canadian and I'm not really clear on this...
From what I understand about the U of Calgary, law school is considered an undergraduate program. Technically, this means that you can get into law school without an undergrad degree, though they do specify that you need at least 2 years of post-secondary education before you can apply. In reality, very few (<<<1%) of successful applicants to the law school actually get in without having an undergraduate degree, so in this way, it definitely isn't a regular undergraduate faculty, either.
And I think that most schools in Canada operate the same way, though correct me if I am wrong, because I'm not really certain.
BTW, I'm gonna apply with 2 undergraduate degrees under my belt
