According to an occurrence summary posted on the Civil Aviation Daily Occurrence Reporting System (CADORS) Wednesday, the pilot advised Transport Canada that the laser appeared to have come from the downtown Corner Brook area.
The interference form the green laser light lasted less than five seconds, according to the report.
The Boeing 737 was on an inbound flight at around 4:20 a.m. when the incident occurred. There were no injuries or damage reported.
No one from WestJet would do an interview about the incident. In an emailed response, a company media spokesperson said WestJet would not confirm this incident, as its operations team does not have a record of it, although it may have been reported to Transport Canada.
The airline cautioned that Transport Canada advises that, for the most part, CADORS reports contain preliminary, unconfirmed data that can be subject to change.
