According to Barbara Smith's book, Ontario Ghost Stories, in August of 1910, eleven men not only saw but heard a ghost ship on Lake Ontario.
The men were out on the lake at night when they heard a repeated whistle. The men came on deck to see a clipper ship complete with oil lamps burning in the windows. They peered through the darkness towards the ship puzzled as the as the whistles meant that the ship was in distress.
A rescue team was formed and sent out in a boat to see what assistance they could render but when they arrived on the scene where the ship should have been, there was nothing to see. The ship simply vanished on a clear night bathed in moonlight.
