Bat ID in Southern Ontario?

So I recentlu discovered there's at least one bat that hunts over the hockey arena flood lights every night near my house. It's remarkable in that it has white spots on the underside of each wing, and a white patch at the throat. I live in downtown in a large city in southern ontario. the bat (there maybe 2 or 3 of them) hunts in a fairly large park in a residential and well treed area.

None of the bats listed as living in southern ontario online seem to have anything mentioning white spots. The other interesting thing is that I can occasionally hear them/it call, but it's much less high pitched than any of the calls we hear on this website, though tonight i heard a more normal bat-like sound.

It flies in a figure 8 ish pattern over the same area.

Can someone tell me what I'm watching? I don't think it's a bird. Birds don't sound like that. But there's really nothing I could find online about this.

Hi lemurs366, could it be the hoary bat (Lasiurus cinereus)? Their habitats include densely vegetated urban areas and were no doubt attracted to insects congregating around the floodlit hockey arena. Their calls are also often audible to human ears. Was the throat colour definitely white? Could it have been yellow? Did it have a white frosting on it's body?

Were the white spots definitely on the underside of the wing? If you look at the photo in this link (http://www.scbat.org/bats-species-of-the-south-coast/hoary-bat-lasiurus-cinereus/ "") there are 3 yellowish spots on the upper wing. Did the underside look anything like the photo in this link: (http://www.factzoo.com/mammals/hoary-bat-largest-north-america.html "") (scroll down to the 2nd and 3rd photos).

These two links also have some more information on habitat, physical description, etc:

Let us know if it wasn't the Hoary Bat you saw. You've got me intrigued now!
