The following excerpt is from O.M. v. S.K., 2020 ONSC 3816 (CanLII):
Parental alienation is a legal concept as opposed to a mental health diagnosis; therefore, the court may make a finding of alienation on an analysis of the facts alone without expert evidence (Malhotra v. Henhoeffer, 2018 ONSC 6472, at para. 107).
In Fielding v. Fielding, Mackinnon J. heard and accepted expert evidence that parental alienation is established if, i. there was a prior positive relationship with the targeted parent; ii. there is an absence of abuse by the targeted parent; iii. the alienating parent uses many of the alienating strategies; and iv. the child exhibits most of the alienated child behaviours (2013 ONSC 5102, at para. 135).
