Lau was born in Vancouver, British Columbia to Hong Kong Canadian parents, who intended for her to eventually become a doctor. Her parents' ambitions for her were wholly irreconcilable with her own; consequently, her home and school lives were desperately unhappy. She also attended Templeton Secondary School in Vancouver. In 1986 she ran away from her unbearable existence as a social outcast and pariah in school and being a tyrannized daughter at home.
Evelyn Lau began publishing poetry at the age of 12; her creative efforts helped her escape the pressure of home and school. In 1985, at age 14, Lau left home and spent the next several years living itinerantly in Vancouver as a homeless person, sleeping mainly in shelters, friends' homes and on the street. She also became involved in prostitution and drug abuse.
Despite the chaos of her first two years' independence she submitted a great deal of poetry to journals and received some recognition. A diary she kept at the time was published in 1989 as Runaway: Diary of a Street Kid. The book was a critical and commercial success; Lau received praise for frankly chronicling her relationships with manipulative older men, the life and habits of a group of anarchists with whom she stayed immediately after leaving home, Lau's experiences with a couple from Boston who smuggled her into the United States, her abuse of various drugs, and her relationship with British Columbia's child support services. The film The Diary of Evelyn Lau (1993) starred Canadian actress Sandra Oh.
Lau had a well-publicized romantic relationship with University of Victoria creative writing professor and author W. P. Kinsella, more than 30 years her senior, which led to the filing of a libel case against her after she wrote a personal essay on the relationship (the essay, "Me and W.P.", won a Western Magazine Award for Human Experience, and was shortlisted for the Gold Award for Best Article). Her work in magazines won four Western Magazine Awards and a National Magazine Award; she also received the Air Canada Award, the Vantage Women of Originality Award, the ACWW Community Builders Award, and the Mayor's Arts Award for Literary Arts. Her poems were selected for inclusion in Best American Poetry (1992) and Best Canadian Poetry (2009, 2010, 2011). Lau has also worked as writer-in-residence at University of British Columbia, Kwantlen University and Vancouver Community College. She currently lives in Vancouver, where she freelances as a manuscript consultant in Simon Fraser University's Writing and Publishing Program. On Oct. 14, 2011, Lau was named the poet laureate for the city of Vancouver. She is the third poet held this honorary position and her plan is to offer ‘poet-in-residence consultations with aspiring poets’.
