The Expedition Helicopters Bell 206B (C-GJID) was flying with a pilot and three passengers. The passengers were checking land claims and were dropped off before the helicopter proceeded to an area where it landed and waited for the passengers. The ground was soft and the pilot landed with caution to ensure the skid gear would not sink into the soft ground. When the pilot received the call to pick up the passengers, the helicopter was started and as the pilot applied collective to lift off, he turned back to look at his skid gear to verify they weren’t stuck. The pilot felt the helicopter rolling to the right and applied opposite cyclic control. The recovered attempt was unsuccessful and the aircraft came to rest on its right side. The pilot secured the aircraft by selecting; the fuel valve to the off position, battery off, and pulled the boost pump circuit breakers. The pilot evacuated the aircraft and after waiting a few minutes to make sure there was no fire, returned to the aircraft and removed the first aid kit and satellite phone. The pilot contacted the company which dispatched a helicopter to the accident site to pick up the pilot.
