An 8-bay antenna does not have to be aimed accurately like a satellite dish at all, but it does have to be aimed.
I have one on a rotor so I can turn it toward Buffalo or toward the CN Tower about ninety degrees to the right (I live in Scarborough). You aim it so it's flat toward the incoming waves similar but not the same as a dish. You do not have to be totally accurate, just within ten degrees or so. I use the signal strength meter on my TV to optimize my aim.
If you are an hour north of Toronto you might be able to get Buffalo stations as well as Toronto stations but I think you will need a long-range antenna for Buffalo.
It is best to mount the antenna vertically but it probably makes little difference if you mount it on an angle. It just looks funny.
There is a lot to get. I get 2,4,5,7,9,17,19,23,25,26,29,36,41,47,49,51,57,67 and 69 with subchannels.
