What happened

While operating over the water, the pilot descended to an altitude that was too low for safe maneuvering. This resulted in the airplane impacting the water surface and crashing. Both individuals on board were able to escape the wreckage and sustained no injuries.
Findings

The pilot made a judgment error by approaching the water surface too closely before attempting to level off the aircraft. Additionally, the crew was conducting low-level flying over Stoney Lake without proper authorization for such maneuvers.
Probable cause
The pilot's error in judgment regarding altitude and unauthorized low-level flying over the water surface led to the impact.
