Dion is preparing for a five-week residency at La Défense Arena, with 16 shows scheduled between September and October 2026. These performances mark her first major run since disclosing a stiff-person syndrome diagnosis in December 2022. In a birthday video message she said she is managing her health, singing again and even moving a little onstage, calling the chance to perform the greatest gift and expressing excitement and gratitude.
She returned to perform post-diagnosis at the 2024 Paris Olympics opening ceremony and later at the Elie Saab show in Riyadh. In April she released "Dansons," a French piano ballad written by Jean-Jacques Goldman.
