Chancy is a founding member of the Haitian Creole Academy[2] and served as Haiti's minister for the feminine condition and women's rights from 2004 to 2006.

[2] This period shaped her advocacy for Haitian Creole:[1]It was at this time, amid a climate of political repression that left a mark on my blood, that I came to understand the role of our national language in the struggle to establish a democratic political regime and to pave the way for progress, development, and national unity.

Chancy was forced to go into exile with her family in 1965, and they settled in Canada, taking up residence in Montreal's Outremont neighborhood.

[7][8] In Montreal, while pursuing a professional career in secondary education, Chancy continued her social and political activism both within the Haitian community and across Quebec society.

[10] She received a master's degree in adult education from the University of Montreal in 1981, writing her thesis on illiteracy among Haitian women immigrants.

[6] Since then, she has held several positions in the public sector, including training director at the National Office for Participation and Popular Education from 1986 to 1987, secretary of state for literacy from 1996 to 1997, and minister for the feminine condition and women's rights from 2004 to 2006.
