In February 1997, the Ontario government decided to close Montfort Hospital in Ottawa. This decision led to a massive mobilization of the Franco-Ontarian community and the founding of the SOS Montfort coalition, which fought to keep the hospital open. After five years of political activism and legal battles, the cause was won. From an historical standpoint, this episode marked a key moment in the affirmation of Franco-Ontarian identity. From a legal standpoint, it confirmed the protections that the Canadian Charter of Rights and Freedoms affords to Ontario’s French-speaking linguistic minority.
