It seemed so perfect, so scientific - a hair test that could objectively determine whether parents of young children were abusing drugs or alcohol. But it turns out the 'Motherisk' hair testing was flawed, and improperly administered all across Canada over twenty years. The results were devastating. Families broken up, children seized and irrevocably adopted out. The Fifth Estate tracked down parents who share stories for the first time on Tainted Tests: Broken Families. Mark Kelley reports. A joint investigation with the Toronto Star and CBC Radio’s The Current.
