Celine's announcement:

"It is with tremendous disappointment that we have to announce today the cancellation of the Courage World Tour.

“I’m so sorry to disappoint all of you once again. I’m working really hard to build back my strength, but touring can be very difficult even when you’re 100 percent. It’s not fair to you to keep postponing the shows, and even though it breaks my heart, it’s best that we cancelled everything now until I’m really ready to be back on stage again. I want you all to know, I’m not giving up… and I can’t wait to see you again!” – Celine xx…

"Tickets purchased for the 42 canceled dates will be refunded via the original point of sale. For further ticket inquiries or options, ticket holders should reach out to their original point of purchase.
