This report from the CBC seems more relialble than the CanWest one posted above.
"Emergency crews are assessing 10 passengers from a flight that encountered turbulence and was forced to make an unscheduled stop in Calgary Thursday morning.
Calgary Emergency Medical Services said they were called for reports of multiple injuries onboard Flight 190 which was en route from Victoria to Toronto.
"It landed safely at 8:30 a.m. MT," said Bryce Paton of the Calgary Airport Authority. "We understand there are no life-threatening injuries."
Air Canada said the preliminary passenger list indicates the plane was carrying
83 passengers and five crew members.
The Airbus A319 is sitting on the tarmac, surrounded by emergency vehicles. There are no visible signs of external damage to the plane, said CBC reporter Erin Collins."
