A Jazz de Havilland Dash 8-400, registration C-GGMI performing flight QK-8936 from Thunder Bay,ON to Toronto,ON (Canada) with 58 passengers and 4 crew, had been holding for about 30 minutes on approach to Toronto, then was cleared for the ILS approach to runway 06L. While the aircraft was intercepting the localizer at 3000 feet MSL about 15nm before the runway threshold at 20:07L (01:07Z Dec 6th) the crew observed sudden and significant airspeed fluctuations, the stick shaker activated. The crew initiated a windshear escape maneouver using maximum power and diverted to their planned alternate Montreal,QC (Canada) where the aircraft landed without further event.

The Canadian TSB reported review of the FDR data revealed a severe turbulence inspection was required and the engines had been overtorqued by the windshear escape maneouver.
