Singer Lady Gaga has canceled the final concert of her tour due to medical advice. She announced on Instagram that she will not perform at the third and final show at the Bell Centre because of a respiratory infection. Gaga expressed sadness over having to cancel the concert and apologized to fans who were looking forward to attending. She said the previous concerts in Montreal were magical and special, and her heart aches for those who were anticipating today's show. Her tour, the Mayhem Ball Tour, began in February in Glendale and has traveled through various cities in North America, including Boston, Washington, and Montreal. The tour was extended into September 2026 with new dates and cities. Gaga has previously canceled several concerts for health reasons, including a show in Miami due to vocal cord issues. She added that choosing arenas allows for greater control over concert details, which is not possible in stadiums.
