The following excerpt is from Children’s Aid Society of the Regional Municipality of Waterloo v. D.B. and B.M., 2021 ONSC 5252 (CanLII):

In Children’s Aid Society of Halton Region v. J.K.V., at paras. 113-114, the court states that the child’s poor school attendance, while in his mother’s care, threatened to undermine his social, emotional and educational development. Although not intentional, and most likely, due to her poor mental health and her suspicious, paranoid and delusional thoughts, these factors nonetheless prevented her from ensuring that the child’s emotional and developmental needs were met. As a result, there was a real risk that he would likely suffer emotional harm.
