Céline Dion announced that she was canceling the rest of her North American tour dates of the Courage World Tour due to muscle spasms in on January 15, 2022. In a statement on her website, she said, «I was really hoping that I’d be good to go by now, but I suppose I just have to be more patient and follow the regimen that my doctors are prescribing. There’s a lot of organizing and preparation that goes into our shows, and so we have to make decisions today which will affect the plans two months down the road.» Dion noted that she would proceed with her European dates for 2022.
However, Dion later postponed these dates to 2023. Not long after this, Dion disclosed that she had been diagnosed with stiff-person syndrome in an emotional Instagram video posted in December 2022. This led her to postpone her tour dates until 2024. She also gave fans insight into her health battle and said, «I’ve been dealing with problems with my health for a long time, and it’s been really difficult for me to face these challenges and to talk about everything that I’ve been going through.»
Dion went on to explain, «While we’re still learning about this rare condition, we now know this is what’s been causing all of the spasms that I’ve been having.» She added, «Unfortunately these spasms affect every aspect of my daily life, sometimes causing difficulties when I walk, and not allowing me to use my vocal cords to sing the way I’m used to.»
