Key Porter Books of Toronto, Ontario, was established by Anna Porter and Richard de Pencier in 1979. In addition to being one of the largest independent trade publishers in Canada, the company maintained an international reputation as a producer of quality books in an extensive range of categories. Key Porter published between 75 and 100 new titles annually in the areas of photography, art, business, finance, Canadian history and biography, memoirs, natural science, politics and current issues. Under the Key Porter Kids (KPK) imprint, the list included non-fiction, young adult fiction and picture books by authors such as Margaret Atwood, Tom King, László Gál, Carol Matas, Henry Kim and Tim Wynne Jones. Key Porter also published fiction using three imprints: Key Porter fiction, Patrick Crean Editions, and Lester and Orpen Dennys Limited. The list included Canadian and international writers such as Joan Barfoot, George Bowering, Sylvia Fraser, Thomas Keneally, Susan Swan, William Trevor and Yevgeny Yevtushenko. Among Key Porter’s non-fiction authors were Jack Batten, Stevie Cameron, Jean Chrétien, Robert Fulford, Basil Johnston, Farley Mowat and Eric Wright. Anna Porter sold Key Porter Books in July 2004 to H.F. Fenn. In September 2009 the company relocated to Bolton, Ontario and incurred a reduction in staff. Key Porter Books went out of business in early January 2011.
