Olivier Rioux was born in Terrebonne on February 2, 2006, to Jean-François, a 6 ft 8 in (2.03 m) photographer and former volleyball player, and Anne Gariepy, who is 6 ft 1 in (1.85 m), and works at the Royal Bank of Canada (RBC). His 6 ft 9 in (2.06 m) older brother, Émile, has also played basketball. The family has resided in the Anjou borough of Montreal[4] and the suburb of Beloeil.
