A seventh concert night for Taylor Swift's Eras Tour appeared on Austin CaldwellTicketmaster's website for Toronto, Canada, on Friday and was quickly taken down.

The additional date for Sunday, Nov. 24, at 7 p.m. at Rogers Centre was up for a few minutes. Ticketmaster's site said, "On sale date and time are in the works - please check back!" and showed a map of the arena. Swifties on Twitter went into a mad-dash panic.

The link has been replaced by a blank page with the message, "This Event Cannot Be Found. You'll be automatically redirected to the homepage shortly, or you may head there now. We apologize for the inconvenience."

Swift is set to perform in Toronto for six nights: Nov. 14, 15, 16, 21, 22 and 23.

Swift's team and Ticketmaster did not reply to requests for comment about whether the additional date on the website was a mistake. At her 100th Eras Tour show in Liverpool, England, the singer said the tour will wrap at the end of 2024.

"This is the very first time I’ve ever acknowledged to myself and admitted that this tour is going to end in December," she said sentimentally before playing her "All Too Well" 10-minute version.

"This tour has really become my entire life. It's taken over everything, like I think I once had hobbies," she joked. "All I do when I'm not on stage is sit at home and try to think of clever acoustic song mashups and think about what you might want to hear."

Swift is in Warsaw, Poland, performing three sold-out shows at PGE Narodowy.
