Is this the University of Toronto? It is a very strong university, very good for math, and admissions is largely stats based (and your stats are excellent). When looking up the cost of attendance, make sure to keep the exchange rate in mind. I think that it is a very good choice and I would leave it on the list (unless you are thinking of some other U of T, in which case I would add Toronto to the list).
I am not a huge fan of ED. I would only apply ED if you have figured out what your #1 choice is, and you are confident that you will be able to afford to go there if you get in.
