Police negotiators were summoned to the Fairmont Pacific Rim hotel about 2:30 a.m., local time, Monday after the man walked into the hotel lobby and displayed the gun to staff. Police say they know the man's identity but they have not released it, the Canadian Broadcasting Corp. reported. He is believed to be 28 and from nearby Surrey, British Columbia, with a history of mental illness.
He has no known connection to the hotel, police said.
So far the man, who is on the second floor in a public space at the hotel, has made no demands other than asking for water, CBC reported.
