Canadian authorities have announced their plans to launch an investigation into the recent loss of the Titan submersible and the tragic deaths of its five occupants during a dive to the Titanic wreckage.

The Canadian-flagged cargo vessel, Polar Prince, had taken the Titan out to sea, but contact was lost approximately one hour and 45 minutes after the submersible was launched into the deep ocean.

The Canadian Transportation Safety Board, as the investigation authority for the support vessel’s flag state, has taken responsibility for conducting a safety investigation into the circumstances surrounding the operation.

The US Coast Guard confirmed that all five individuals on board the submersible had perished due to a catastrophic implosion.

A debris field was discovered on the seafloor, located 1,600 feet (500 meters) from the Titanic’s bow.

The multinational search-and-rescue operation came to a somber conclusion after capturing worldwide attention for four days following the disappearance of the small tourist craft in the North Atlantic.

The Transportation Safety Board, which focuses on enhancing transportation safety without assigning blame or determining liability, has dispatched investigators to gather information, conduct interviews, and assess the incident in St. John’s, Newfoundland.

The agency will also coordinate its efforts with other relevant organizations. The majority ownership of the Polar Prince belongs to the Miawpukek First Nation.
