Canadian cinema refers to filmmakers and the filmmaking industries in Canada. Canada is home to several film industry (production and distribution) centres: primarily Montreal, Toronto, and Vancouver. Industries and communities tend to be regional and niche in nature. Many Canadians migrate to the American industry in search of success - Canadian filmmakers such as David Cronenberg, Paul Haggis, James Cameron, and Norman Jewison have all received accolades and awards from the world's most prestigious honorary organizations. (James Cameron directed the highest grossing movie of all time, Titanic).
