I think you will at least get into Ryerson and Windsor. Ryerson is a brand new law school, so I doubt people with high LSAT scores will apply there. If I were you I would rewrite if I feel I could break into the 160s.
The deadline for Jan has passed. But if you did register, you should definitely rewrite. You might get in at Ottawa, Windsor and Ryerson as you stand now, but you'll most likely get wait listed at the rest.
