I also think that you should go to Windsor. Although Dalhousie is stronger in corporate law than Windsor, Windsor also places a number of students in corporate law. Unless you want to practice law in other provinces, go to Windsor because you want to practice in Toronto.
If you are interested in corporate law and want to get a job on bay st at a bigger firm, i would have a look at the distribution of students who secured jobs on bay st from the respective schools. If you know of any firms youre interested in, look into those numbers specifically.
If you have any questions about Windsor specifically feel free to PM me. Im a 1L and interested in the corporate route.

I agree with all of this. There are also some very desirable Ontario law jobs that don't do OCIs that may only be accessible to people towards the top of the class.
I'd also just add that there isn't a 1:1 correspondence in class rank and success in obtaining an OCI position. I know lots of people who had below average 1L marks (ie bottom half of the class) who landed an OCI gig and some above average who did not.
