In what circumstances have social services been found to have made a warrantless apprehension and application for a supervision order?

In Child and Family Services of Western Manitoba v. K.B., 2006 MBQB 94, the agency made a warrantless apprehension and applied for a six-month supervision order. The parents applied to have the apprehension quashed. Menzies J. concluded that the agency misled the court. The social worker told the court that the father had been informed by his son that the son had, two years earlier, sexually abused his sister (the child taken from the father). The social worker reported that the father did not believe his son and did not report the incident. The social worker deemed the child in need of protection and placed the child with her mother.
