What are some good schools for martial arts in the North York region or even all of Toronto?

So basically, I'm looking for a really good Martial arts teacher in the North York region or even all of Toronto that you would be able to recommend. The style of which he/she teaches isn't really important because I really don't have a wide knowledge of the different styles. I would just like to hear from the public view as to some of the best teachers out there, and in a reasonable distance. I currently live at Dufferin and Finch and don't mind travelling an hour on the bus for quality. Thanks in advance.
