"Battling cancer for a few years, it's in the uttermost discretion and surrounded by his family that Daniel Dion, 59, died today, January 16," a statement given to ET read. "He was the eighth child of Thérèse and Adhémar Dion, brother of Céline."

Daniel spent his final days at Maison Adhémar-Dion, a palliative care center in Terrebonne, Québec, a suburb of Montreal.

On Friday, Celiné's rep confirmed that Daniel was fighting a serious battle with cancer, and Celiné and Daniel's sister, Claudette, told The Journal of Montreal that Daniel only had "a matter of days or hours" to live.

After the family learned Daniel was dying, they gathered by his bedside.

Daniel leaves behind his mother, Thérèse Tanguay-Dion, his two daughters, Valérie and Marie-Michelle, two grandchildren, Matis and Laurianne, and 13 brothers and sisters.

A memorial service will be held at Salon Charles Rajotte in Repentigny, on Jan. 23, followed by a funeral a few days later at St-Simon-et-Jude in Charlemagne, Québec, where the family was raised.

"Taking in consideration the reserved character of their deceased brother, the family wishes respect and discretion from the media," the statement continued.
