Anne Denoon was born long ago in Toronto. She studied art history at the University of Toronto in the 1960s, and again in the late 1970s, finally completing her degree in 1980. In the 1960s she worked at a travel agency in London, England, as a gallerina at the Carmen Lamanna Gallery, Toronto, and as a salesclerk at Classics Little Books, Montreal.

For most of the 1970s she lived in France, the Netherlands and England. During the first half of the 1980s she worked in at the Art Gallery of Ontario. In the late 1980s and the 1990s she did freelance editing and contributed regular reviews to Books in Canada, as well as interviews with Carol Shields, Peter Robinson and Joyce Marshall.

In 2002 the Porcupine's Quill published her first novel, Back Flip, a social comedy set in the Toronto art world of 1967. Back Flip was widely and positively reviewed: in the Toronto Star, the Globe & Mail, Quill & Quire, Books in Canada, Canadian Literature, The University of Toronto Quarterly, Now Magazine, Broken Pencil and on the CBC website.

She read from and discussed Back Flip at the Art Gallery of Ontario, the Humber School for Writers, the Arts and Letters Club, the Metro Toronto Reference Library, the Mississauga Central Library and (as part of the "Isaacs Effect" project) the Textile Museum of Canada. Back Flip was referenced in the Market Gallery's 2009 "Lit City" exhibition, and in Amy Lavender Harris's Imagining Toronto (Mansfield Press, 2010).

With support from the Toronto Arts Council, she has completed a second novel, Hindsight, a literary farce about love, envy and plagiarism in 2009 Toronto. She is currently working on a long story that takes place in Paris in 1965.
