AbstractThe 1983 case Racine v Woods is the leading child protection case from the Supreme Court of Canada, distinguishing bonding and/or attachment as a more important determinant of best interest for an Indigenous child than cultural connection. Using this case, courts are upholding the permanent placement of Indigenous children in non-Indigenous homes as opposed to placement within their culture. Racine v Woods reflected knowledge of attachment and family at that time but runs counter to current knowledge. Reconsideration of the factors to decide cross-cultural adoption is needed. The essential point is that attachment assessment draws from a dyadic relational theory and is being applied to communal family systems, such as Indigenous systems. Such a review is consistent with the calls to action of the Truth and Reconciliation Commission (TRC) as well as its predecessor, the Royal Commission on Aboriginal Peoples (RCAP), and recent Canadian Human Rights Tribunal (CHRT) decisions.
