samn99,
I would disagree (somewhat) with Jenste regarding the safety differences between York and Ryerson. Ryerson is downtown and a pretty awesome campus if you love city life, but I would not say it is exceptionally safe. People are regularly assaulted in the area and occasionally on campus as well since anyone can walk into a building (and do). There are also lots of thefts of personal belongings so you really have to be vigilant. York has different issues. The campus is so sparse (personally, I hate it) and you may not necessarily feel safe walking around at night, especially alone. This has nothing to do with being 'near' jane and finch, it is just the campus itself.
But having said that, at the end of the day, you will have an MSW no matter where you go. If you are really into anti-oppression and grassroots activism, I would say choose Ryerson because no school is better at this than they are. If you are more interested in social justice, choose York.
edit: I see you went with Ryerson, good choice
