OPP Commissioner Julian Fantino says he'd like to see all boaters be required to wear life jackets or personal floatation devices at all times.
Twenty-three people died in 2008 while boating on waterways policed by the OPP and this year 20 people have perished.
Only two of this season's casualties were wearing life jackets.
Fantino says it's been a summer filled with needless tragedy and many of the deaths would have been prevented by life jacket use.
