You'll need about a 3.5 best 3 years for a shot at Osgoode. Their index cut off last year was somewhere around 3.62, and your 171 gets converted to a 4.0.
((3.62 x 4)-4.0)/3 = 3.49333
I forget the Uvic index, but IIRC, you also need about a 3.5+ on their scale (with drops) no matter how good the LSAT. You are a lock for UBC. I got in with a similar LSAT and substantially lower GPA. U of T, I think you have a shot, but it's probably less than 50/50. You should be good for both Queens and Western. Ottawa and McGill are tough to say. Ottawa gives almost zero weight to the LSAT and basically demands a 3.5+, while McGill doesn't even require the LSAT, and admits a large portion of Quebec/french language students, so I imagine they give it far less weight than they do GPA. If you're tempted to do the US thing, you should get into most of the following: Penn, Michigan, Virginia, Duke, Cornell, Georgetown, Northwestern, and possibly even Chicago or NYU.
