Crozier has authored fifteen books of work, which typically focus on human relationships, the natural world, language, memory, and perception. Alongside partner Patrick Lane, Crozier has co-authored No Longer Two People (1979), and co-edited Breathing Fire: Canada’s New Poets (1995) and Breathing Fire 2 (2004).
A book review from The Globe and Mail by Jacqueline Baker on Crozier’s book, "Small Beneath the Sky: A Prairie Memoir", emphasized Crozier’s prairie roots, and gave positive feedback on this memoir. In an interview with Joseph Planta of THECOMMENTARY.ca regarding the same book, she reveals the alcohol and poverty that surrounded her as a child. Although she grew up with a fairly difficult childhood, Crozier took her past and turned it into well renowned poetry.
She has received a 1992 Governor General's Awards, the Canadian Author’s Association Award for Poetry, the National Magazine Award (Gold Medal), and first prize in the National CBC Literary Competition. Crozier received the University of Victoria’s Distinguished Professors Award and the University of Regina presented her with an honorary Doctorate of Law in 2004.
Crozier has given various benefit readings for organizations such as the Society for the Prevention of Cruelty to Animals, Wintergreen Studios, The Land Conservancy of British Columbia, the Victoria READ Society, and PEERS, a group devoted to getting prostitutes off the streets. She has read her poetry on every continent other than Antarctica, and on 19 May 2005 Crozier recited a poem for Queen Elizabeth II as part of Saskatchewan’s Centennial Celebration.
In 2009 she was made a Fellow of the Royal Society of Canada and in 2011 Crozier became an Officer of the Order of Canada.
