Renowned musicians Sheku and Isata Kanneh-Mason have been forced to cancel their sold-out concert in Toronto after Air Canada refused to provide a seat for a priceless cello valued at $4.5 million. Despite purchasing an extra ticket specifically for the instrument, the airline denied it boarding, leading to travel complications. This incident has sparked outrage among fans and highlighted ongoing issues related to airline policies regarding musical instruments. The Royal Conservatory of Music is working to secure a new date for their performance.
