Noticed it as soon as I wnt outside.Im a Sky watcher who knows magnitudes of other stars and the planets at the moment. It was brighter than anything, over toronto. I have witnessed a UFO like this before a while ago so it immediately caught my attention. Behaved the same way as my reoccuring UFO in 2012, hovers and moves at different suttle speeds, floats down on and angle then zooms up straight. I had 2 wittnesses this time. We were parked in a car near houses so I used the roof of a house to determine where the UFO was and how it was moving.. about 40 minutes after the UFO went down past the roof so we couldnt see it from where we were anymore.
