A Summit Air Avro RJ-100, registration C-FRJY performing flight SUT-8225 from Thunder Bay,ON to Waterloo,ON (Canada) with 31 passengers and 4 crew, was climbing through FL300 out of Thunder Bay when the cabin climbed through 8000 feet of altitude. The crew worked the related checklist, the cabin altitude continued to rise however. The crew requested a descent to 10,000 feet, donned their oxygen masks and initiated an emergency descent to 10,000 feet, the passenger oxygen masks were released. The crew determined that the #2 outflow valve was stuck open in about 1/3 open position. After levelling off at 10,000 feet the crew was able to regain control over the #2 outflow valve and the cabin altitude. The aircraft continued the return to Thunder Bay and landed safely back about 75 minutes after departure.
