Elton was scheduled to perform at the Peterborough Memorial Centre Saturday night but it never happened.
At about 8:15 p.m., it was announced he had taken ill and wouldnt be able to take the stage.
A disappointed crowd of an estimated more than 5,000 people left the arena. Many had come from out-of-town to see the entertainer and some were seeing him in person for the first time.
Sue Warrington, Memorial Centre arena division manager, advised fans to hold onto their tickets as they would try to reschedule him for another performance at a later date, and as soon as possible.
