North Shore, Lake Ontario
I was located in Oakville slightly east of Trafalgar Road.
This double orb was travelling west to east (I was on the north shore). It was very close to the water's surface and eventually appeared to submerge.
During the clip, I move the camera so as not to lose the orb behind the time and date, or off the screen altogether.
Note that I mention the "beam" some time before the beam actually appears below the lights. This beam could, of course, just be the reflection, but is often seen even in very rough, choppy conditions.
