CALGARY – A **** ****** believed to be a hoax prompted WestJet to divert a Vancouver-to-Toronto flight to Calgary on Wednesday night.

WestJet said flight WS722 landed safely and the 30 passengers and five crew members on board exited the aircraft via stairs.

The ******* said it had diverted the **********-700 “out of an abundance of caution” and later said the flight had been “cleared as safe by Calgary ******” and no ********* device was found.

WestJet said the passengers were to continue to Toronto on other flights later in the evening.

This was the fourth time in five days that a WestJet flight had been the subject of a ****** and it was the fifth such ******** involving a Canadian airliner in a week.

On Tuesday, a WestJet flight with 113 passengers and five crew members landed on a flight from Toronto to Saskatoon landed at Saskatoon following a ****** but ****** say a search of the aircraft found no ****.

A WestJet flight en route from Edmonton to Toronto was forced to divert to Winnipeg on Monday night because of an unspecified ******. Six passengers suffered minor ******** during the **********.

Last Saturday morning, a WestJet flight from Edmonton to Halifax landed in Saskatoon after ****** said a call had been made claiming an ********* device was on board.

And, last Thursday, St. John’s International Airport was temporarily closed because a note was found in the washroom of an ********** flight that authorities considered a potential **** ******.

In all of the cases, searches of the aircraft unearthed nothing suspicious.

****** say the ************* is continuing and there have been no arrests.
