Denis was born in Grenville, Quebec. At age 9, his parents divorced and he went on to live with his mother in Hawkesbury, Ontario. After a brief stay with his father, he was put in a juvenile detention centre because he had been hooked to smoking marijuana. At the age of 14, he escaped from the center he was assigned to and started living as a street kid in the streets of Montreal acquiring addiction to hard drugs in the process as a teenager.
Denis assuming the pseudonym "Roach" became a squeegee teenager sleeping in parks, abandoned cars and refuge centres and was arrested many times. It was during these troubled times that he met EyeSteelFilm's director Daniel Cross who was planning to shoot a documentary film about squeegees and amazingly Roach offered to tell his part of the story by film thus beginning a prosperous career as a well-known documentary filmmaker and activist.
Eric Denis began first by documenting his own life as an autobiography, entitled "RoachCam" as part of the acclaimed S.P.I.T.: Squeegee Punks in Traffic directed by Daniel Cross and Mila Aung-Thwin.
Using cinema as a motivation to get cleaned up, "Roach" has gone on to make two other films with EyeSteelFilm: RoachTrip is his directorial debut film. It is autobiographical take about the invisible punk highway from Quebec to the orchards of British Columbia. In August 2004, the film went on to win the second prize in the "Portraits" category" in Tver festival in Russia.
He recently directed Punk the Vote!, again an autobiographical documentary which saw Roach and fellow punker Starbuck run for Canadian federal elections against Liberal incumbent Jean Lapierre, in an informative, hilarious take on Canadian politics punk-rock style. Eric Denis didn't win the election. Roach had 101 votes. His main goal in this film was to give the homeless the opportunity to vote.
From his works also is the short film ZLEA: Zone Libre d'Expression Anarchiste (translated as Free Zone for Anarchist Expression) in 2005.
Eric "Roach" Denis' films have played in festivals such as Hot Docs Canadian International Documentary Festival, in Tver (Russia), DocsDF (Mexico City) and Nemo (Paris).
He is currently making Les Tickets, about the bureaucratic tricks used by the police to arrest homeless people.
