Collision and fall overboard
On 29 August 2016, a rigid-hull inflatable passenger vessel, commonly known as Aventure 6, with 9 people on board, collided with a marine mammal while conducting a whale watching excursion off Grandes-Bergeronnes, Quebec. A passenger and the operator went overboard and suffered hypothermia; the operator also sustained head injuries. Another passenger was treated for impact-induced injuries. The vessel sustained damage to both outboard engines.

Transportation Safety Board investigation process
There are 3 phases to a TSB investigation:
- Field phase: a team of investigators examines the occurrence site and wreckage, interviews witnesses and collects pertinent information.
- Examination and analysis phase: the TSB reviews pertinent records, tests components of the wreckage in the lab, determines the sequence of events and identifies safety deficiencies. When safety deficiencies are suspected or confirmed, the TSB advises the appropriate authority without waiting until publication of the final report.
- Report phase: a confidential draft report is approved by the Board and sent to persons and corporations who are directly concerned by the report. They then have the opportunity to dispute or correct information they believe to be incorrect. The Board considers all representations before approving the final report, which is subsequently released to the public.
