Just found this video posted a year ago which maps out the mystery of the floating feet (in a pretty odd reporting style).

Link to BBC News article

"Police have said it is possible the feet come from the passengers aboard a small plane which crashed into the water in the region several years ago - their bodies were never recovered.

The Coroners Service of British Columbia has investigated this idea but to date, it has failed to match DNA samples collected from members of the crash victims' families with DNA obtained from some of the mystery feet."
