The same airline had a pretty serious accident in 2010 resulting in the death of all pax:
Aviation Investigation Report A10P0147 - Transportation Safety Board of Canada
However, this was likely due to intoxicated passengers interfering with flights controls
"What was happening in the cabin moments before the pilot lost control cannot be accurately determined. However, it can be concluded that this probably involved activity by the unsecured passengers that interfered with the pilot and his control of the aircraft."
"The passengers were intoxicated, however, they were able to walk and were sufficiently coherent to argue about the price of the charter."
