Born in Vancouver, Canada, Byron's artistic background was deeply rooted, with his father being a musician, his mother an artist, and his grandfather, the renowned painter and Order of Canada recipient, Toni Onley. His great-grandfather, Jim Onley, was a well-known stage actor in the UK during the 1930s and 1940s before emigrating to Canada in 1948.
As an only child, Byron had an insatiable desire to be the center of attention and in the spotlight. He began his career as a street entertainer at the age of 16, inspired by learning how to juggle during a summer program for the performing arts. Under his stage name, "Byron from England," his comedy, escape, and juggling show was a massive success at festivals and fairs in over a dozen countries.
In 2002, Byron transitioned to a full-time stand-up comedian, utilizing his natural talent for voices, accents, and impressions, which made him a favorite in his home country of Canada and earned critical acclaim abroad in the US, UK, and Australia. The Melbourne Herald Sun praised his performance, stating, "He had the crowd cheering and this reviewer wanting more" with 4 stars.
Byron's television appearances include playing a guard on Alcatraz and the hilariously whiny husband, "Pam, can you call my mom?" in the NyQuil commercial.
