Mr. Rankin says Mr. Lui had a history of heart problems but he isn't sure what caused his death on Wednesday.
Lui was a prominent member of the performing arts scene in B.C. for more than 40 years, founding Ballet BC and Dance Spectacular, later replaced by the Dance Alive series.
He also was founding artistic director of the cultural program at the Canadian International Dragon Boat Festival and the developer behind the Scotiabank Dance Centre, which is celebrating its 10th anniversary this year. A rooftop garden at the centre is named after him.
