Saskatoon police said a threatening call was received, reporting that a bomb was on board the Halifax to Edmonton flight. The flight landed in Saskatoon at about 9 a.m. CST as a precautionary measure.
The plane was diverted to Saskatoon because of the threat. All passengers are off the plane.
One passenger yelled "we're all good" to reporters while disembarking.
Other passengers noted the mood on the plane was relatively calm.
Wade Wick said no one on board knew anything was wrong. He said he wasn't too worried.
Saskatoon Police spokeswoman Kelsie Fraser said about 150 crew members and passengers had to be taken off the plane once it landed.
"It's a criminal investigation at this point," Fraser said.
Police continued to search the plane in the afternoon and nothing suspicious was located.
