It is uncertain why there has been an increasing number of 'emergency removals' of children from parents over the past twenty years. One plausible answer is an increase in defensive social work. Child protection workers are generally drawn to their work for the best of reasons, to assist children and families. When severe injuries and even deaths occur to children, with whom CPS has had a history, social workers and the Ministry itself have received adverse publicity. When the media have sensationalized such stories, a defensive tsunami of removals has typically occurred. One might deem this erring on the side of safety, on the side of the best interests of the child, yet it has often been an unnecessary over-reach, an exaggerated attempt to do what is right. What must not be overlooked is the extent of harm caused by unnecessary removals. The stresses sustained by affected families can provoke psychological, financial and marital harm. The Child Welfare system becomes stressed because unnecessary removals divert resources, overcrowd the courts leading to lengthy delays of process and to terms that children must remain in foster care.
