Moore was born in Montreal, Quebec. He grew up in a part of the city where the people mostly spoke English, instead of French. His first job in journalism was as a reporter at the radio station CHOM-FM in Montreal. He has also previously worked for Radio-Canada. He also hosted "Mystery Ink", a show about mystery fiction that aired often on the television channel Mystery TV. Moore starts the show by interviewing an author. Next, he may speak with detectives or look at classic movies. The final stage is a crime story or he may speak about untrue facts.
