Uncommanded Roll Incident

[J.O.]

A Canadian North Boeing 737-300, registration C-FGCN performing flight 5T-1517 from Fort MacKay Albian,AB to Edmonton,AB (Canada) with 139 people on board, was climbing through about 800 feet AGL when the aircraft began to uncommandedly roll left. The crew countered by applying full right ailerons, the roll to the left however continued. Airspeed began to decay, the crew applied nose down inputs, however, the aircraft reached a nose up attitude of 28 degrees despite the control column commanding nose down. The airspeed finally recovered and increased permitting the crew to retract the flaps after which the left roll ceased. The crew checked engine parameters and configuration with no anomalies detected and decided to continue the flight to Edmonton for a safe landing with no further anomaly observed.

Eerily similar to the AC 320 loss of control incident departing BOS years ago. Cause was asymmetric deicing.

Asymmetric flaps possibly?

Id also be inclined to land at nearest suitable airport and not risk another control incident. IE return to land.

Has 'uncommanded rudder movement' been ruled out? I believe there is an SOP for roll-due-to-uncommanded-rudder.

Based on what little we know, I immediately wonder if that part I've highlighted was the chicken or the egg.
