A Westjet Encore de Havilland Dash 8-400, registration C-GWEQ performing flight WS-3268 from Regina,SK to Winnipeg,MB (Canada) with 41 people on board, was on takeoff from Regina's runway 31 when upon applying takeoff power the crew noticed the left hand engine's (PW150A) oil pressure increased to 72psi into the yellow caution band, decreased to 71psi before increasing again to 72psi. The crew rejected takeoff at high speed (92 KIAS), the oil pressure subsequently decreased to 68psi and stabilized as the engine power decreased. The aircraft stopped on the runway, emergency services responded.

The Canadian TSB reported that after coming to a stop the engine oil pressure stabilized within limits, the crew advised emergency services were no longer needed and taxied the aircraft to the apron. Company maintenance instructed the crew to perform a 2 minute takeoff power up run on the left hand engine and monitor the oil pressure. The run up went without anomaly with the oil pressure remaining between 68 and 70 psi. Maintenance cleared the aircraft for departure.

The occurrence aircraft reached Winnipeg with a delay of 4 minutes (after the aircraft departed the gate in Regina 10 minutes early). The Canadian TSB annotated referring to the flight from Regina to Winnipeg: "The subsequent flight was uneventful."
