Ladouceur suffered from pancreas cancer, a disease he found out he had in August 2013.
He published a book in April 2014 called "Dejoue par le cancer", which had a preface written by former Quebec Nordique Peter Stastny. He also published a second book called "Raconte-moi les Nordiques."
Ladouceur worked for the Journal de Quebec and was last featured in their paper in mid-April.
He was born in Montreal on December 14, 1951 and started out at the Montreal-Matin in 1973 where he contributed to coverage of the Montreal Canadiens. In 1979, he started to cover the Quebec Nordiques.
Ladouceur is one of the rare journalists to cover every season the Nordiques had in the National Hockey League before they moved to Colorado in May 1995.
He also had a good reputation as a boxing journalist.
In an October 2013 interview, Ladouceur noted his coverage of the boxing world championship between heavyweights Muhammad Ali and Leon Spinks in September 1978 in New Orleans as one of his most memorable moments of his career.
