An Air Canada flight from Victoria to Toronto experienced a bumpy ride which necessitated an emergency landing in Calgary, Alberta Canada.  Air Canada Flight 190, an A319 with 88 people on board, was en route from Victoria to Toronto when the crew advised ATC of an aircraft upset that resulted in the aircraft doing a roll.

The flight was in the vicinity of the ONSET intersection (Washington state) about 65 NM southwest of Cranbrook, British Columbia when the crew informed Seattle Center that they were having difficulty controlling the aircraft. It is not known at this point if there was a flight management system problem or whether this event was related to turbulence. Vancouver Air Traffic Control accepted control of the aircraft at 1450z. The crew declared an emergency, requested diversion to Calgary International Airport and requested medical assistance upon arrival.

Air Canada 190 landed about 30 minutes later at 1529Z and stopped on Runway 34 for visual inspection of the aircraft by airport emergency response personnel. The crew then taxied off the runway at 1533Z.  It was reported that there were some passengers with serious injuries. Medical assistance was on standby upon arrival.
