During the 1980s, she was living in New York, where she wrote a weekly column on New York life for "The Globe and Mail". She eventually retired her column with the "Toronto Star" in 2005. Landsberg has written three bestselling books, including "Women and Children First", a collection of her campaigning columns; "Michele Landsberg's Guide to Children's Books"; and "This is New York, Honey!", which is a memoir of her time living as the spouse of Canada's ambassador to the United Nations. She wrote The Women's Dayenu:    Landsberg is an outspoken critic of the False Memory Syndrome Foundation and is known for challenging the credentials of foundation advisors, saying that they "are people who really do have powerful motivation to deny the truth". Landsberg is the recipient of two National Newspaper Awards, the YWCA Women of Distinction Award, the Dodi Robb Award from MediaWatch, the Robertine Barry Prize for journalism from the Canadian Research Institute for the Advancement of Women, the Florence Bird Award from the International Centre for Human Rights and Democratic Development, several honorary degrees, and the Canadian Governor General's Award in Commemoration of the 1929 Persons Case and Democratic Development, an award acknowledging contributions to equality for women which have resulted in positive change.
