VANCOUVER John Heilig was one of Canada’s leading voices on ski jumping and Nordic combined, but after a day of working on the Beijing 2022 Olympic venue, he died suddenly. “He’d been working hard on the hill all day,” said Tim Gayda, a former colleague and friend of Heilig’s. “Something happened at dinner, and unfortunately he sort of stopped breathing.” He said the cause of Heilig’s death isn’t yet known, but it may have been a heart attack. “It was just devastating,” Gayda said. “I think that everyone who knows him, worked around him, worked for him or managed him, was really a pleasure.”
