It's going to suck moving away and paying for rent as well in TRU but I don't want to take the risk of having a gap year and still not getting a good enough LSAT score for UBC so I'd rather just attend TRU in that case (if I get in) fingers crossed!
I don't think re-writing in January would hurt your application this cycle, but I'm not sure how much you'd be able to raise your score in the 1.5 months left to study.
Besides, you have a reasonable shot at getting into Ryerson with your stats. Both your GPA and LSAT are well within the range of those who were accepted last year. Having said that, applications are way up this year, so its likely to be a very competitive cycle. I'd save that LSAT re-write and if you don't get in this cycle, then study really hard for the LSAT over the spring/summer and get your mark up for next September.
