UCal fills a niche in admissions in that experience really can for once offset lower marks, so if that fits you, I'd apply. No reason not to.
As for rankings of schools, ask yourself what you want to do after law school. There is a definite pecking order, but it really depends what you want to do.
Corporate law = reputation MATTERS, and there is a genuine difference in where you go (and it doesn't stop with UofT; For Toronto it goes something like UofT, Osgoode, Western/Queens, Ottawa/Windsor)
IP Law = reputation extremely important (UofT, Ottawa come to mind)
Litigation = nobody cares
Immigration law = nobody cares
Government = no one cares, minus certain positions in which case you better be in McGill followed by UofT
Criminal law = nobody cares
See what I'm getting at?
