Lady Gaga canceled a Montreal concert hours before she was due onstage Monday, saying she was too ill to perform and did not want to give fans anything less than the show they expected.
In an Instagram Story posted on 6 April, Gaga said she was unable to perform that night and had to cancel the show. She said she had been fighting a respiratory infection for the past few days, that it had gotten worse, and that her doctor had strongly advised her not to perform. She apologized to everyone who had made plans to be there and support her.
The canceled date was part of her Mayhem Ball Tour, which the singer has been on since July 2025. The 86-show run is due to wrap at Madison Square Garden in New York City on 13 April, leaving only a short stretch left on the schedule. Gaga also attended the 2026 Grammys in February, where she won the Best Pop Vocal Album trophy for Mayhem, and she has also been busy planning her upcoming wedding to fiancé Michael Polansky.

The timing leaves little room in the tour to absorb a setback, and Gaga’s own explanation made clear this was not a scheduling choice but a medical call. She said she did not think she could deliver the quality of performance her audience deserved, a direct admission that the illness had crossed the line from manageable to impossible for a live show.

For fans who had been waiting for the Montreal stop, the answer is plain: the concert was canceled because Gaga was too sick to perform safely or well enough, and her next scheduled milestone remains the tour’s finish in New York on 13 April.
