SiR was set to perform in Toronto tonight July 30th at the Drake-co-founded music venue.

Rapper ScHoolboy Q, who had his show cancelled there earlier this month, implied there is a ban on artists from Kendrick Lamar’s former label after his feud with Drake. Another last-minute concert cancellation at History in Toronto is causing online speculation related to Drake’s feud with Kendrick Lamar. Los Angeles R&B singer SiR was set to perform at the venue on July 30th, but announced on Twitter that the show has been cancelled.

ScHoolboy Q and Lamar are former label mates on Top Dawg Entertainment (TDE), which Lamar left last year, as well as former members of the group Black Hippy. SiR is also on the label and has also collaborated with Kendrick Lamar.
