Her mother, a white francophone woman, was ostracized by other members of her family in the 1950s for having married a black man.

Political career
Biddle had strong connections with the leadership of Vision Montreal before seeking political office herself; her partner Allan Patrick was an organizer for the party in the 1994 municipal election and subsequently became an advisor to mayor Pierre Bourque on issues affecting Montreal's anglophone community. Biddle was elected to city council in the 1998 Montreal municipal election, narrowly defeating longtime Democratic Coalition incumbent Sam Boskey in Décarie. During the campaign, she highlighted her connections to the mayor and promised that the city would purchase the vacant Cinema V building to create a cultural centre for local artists and musicians. Vision Montreal won a majority government in this election, and in November 1998 Biddle was appointed as an associate member of the Montreal executive committee. Following extensive lobbying by Biddle and Patrick, the city purchased Cinema V for $571,000 in August 1999. The following June, council awarded a one million dollar grant and title to the former cinema building to the non-profit Cinema VI Corporation, a successor body to the Fool House Theatre Corporation. Biddle introduced the council motion to end debate on the issue, immediately prior to the final vote. Some councillors strongly criticized the award; prominent among them was Marvin Rotrand, who had previously drawn attention to the high costs of renovating the site and noted Biddle and Patrick's historical links to the Cinema VI group. Patrick angrily rejected suggestions of a conflict-of-interest, saying that he was not a member of the new corporation's board. in the 2001 municipal election. She ran for borough mayor of Côte-des-Neiges–Notre-Dame-de-Grâce in 2005, but was defeated by MICU incumbent Michael Applebaum.
