Because I grew up and lived in Toronto my entire life, did my undergrad at UofT, and wanted to get out of Toronto for once.
And I don't regret my choice at all, but I did find the teaching at UofT to be better compared to what I experienced in Ottawa. Now I have no idea how the UofT law professors compared to the Ottawa law professors because all I have is my undergrad experience.
FYI, read the LSO recruitment procedures for 2L. They identify your obligations as a student wishing to participate in OCIs....I believe one of those obligations is to inform all potential firms still considering you when you have accepted an offer.
