These things still fly over Port Hope. I saw them 2 days ago and another on Canada day. It is not a helicopter and way to low to be a satellite. I’d doubt if it's anything from Trenton, because it's way to public, but there is an F-18 scramble base outside Picton and the U.S is pretty close.
A lot of these sightings seem to happen around Nuclear power and Radio active areas, This area is perfect for sightings in that way. I have never seen them do any crazy maneuvers though If it knocks out cell phones maybe it's some sort of surveillance plane.
