Williams was born to Canadian parents in
Port of Spain, Trinidad. Returning to Toronto, Williams opened a studio in 1930, located on Cariboo Avenue in North Toronto in a house she rented from Arthur Lismer. The studio was in operation for almost 30 years. The studio received over four hundred commissions across Canada for both public and private spaces. An interview with Williams about her career is available in
Library and Archives Canada under
Joan Murray fonds, R4917. Williams was a member of
Royal Architectural Institute of Canada (RAIC) and the
Royal Canadian Academy of Arts. She died in 1997 in
Parry Sound, Ontario. She had previously donated lakefront land for a public park on Mill Lake, now known as Yvonne Williams Park. ==References==
