A Wasaya Airways de Havilland Dash 8-100, registration C-GJSV performing flight WSG-712 from Thunder Bay,ON to Sioux Lookout,ON (Canada) with 17 people on board, had just reached cruise altitude 16,000 feet when a whistling noise started in the cockpit, which persisted between 6 and 8 minutes. After the noise subsided the crew received a "2 Hyd Iso Valve" caution light and indication of the #2 hydraulic system losing fluid. While the crew performed the associated checklists, the crew also received indication of the #1 hydraulic system fluid being hot. The crew consulted with maintenance and subsequently decided to return to Thunder Bay. The crew declared PAN, carried out the cabin preparation checklist with the flight attendants and made an announcement to the passengers. The final steps of the #2 hydraulic failure checklist were carried out including manually extending the landing gear. The aircraft landed safely back in Thunder Bay about 65 minutes after departure.

The Canadian TSB reported maintenance replaced the pressure line to the landing gear selector. Other affected components and filters were replaced and serviced. The hydraulic systems tested serviceable.
