You'll probably want to specify some problems/areas in your SOP, but it's better to admit you're not 100% sure yet than to pinpoint an exact problem when you're not sure.
I don't know much about Ryerson but I'd suggest applying to at least 3-4 schools to have a wider net.
York isn't a bad idea,Waring, Dimmock, and Cragg seem to be in your area. Queens has Schüklenk,Sypnowich, and Pratt. Guelph was recommended to me but I won't be applying there, but Dr. Harvey fits well with your project too. McMaster is also a thought, for ones close to Toronto.
