Camping near Grand Bend. Seen a brilliant white star-like object descend quickly with what looked like a controlled descent then completely disappear over the campsites. Witnessed by one other person. Approx 15 mins later my companion noticed two white-silver spheres floating across the sky at the same slow speed as if by invisible tether.... from one side of tree line to the other. Kept a steady slow and straight course. No sounds. Very strange. Both objects appeared directly overhead.
