Timeline of Events Related to the Independent Review Of The Motherisk Hair Analysis Program

Ministry of the Attorney General

October 21, 2014 - The Court of Appeal for Ontario sets aside Tamara Broomfield's convictions for administering cocaine to a child, and orders a new trial so that the competing expert opinions about the results of the Motherisk testing can be considered. The court concludes that there was conflicting evidence about the reliability of hair testing methods used by Motherisk to determine chronic cocaine ingestion and that this evidence was relevant to these convictions. 

November 28, 2014 - Ontario appoints former Ontario Court of Appeal Justice Susan Lang to lead an independent review of the Motherisk hair analysis program, specifically examining the adequacy and reliability of the immunoassay biochemical hair-testing method used by Motherisk between 2005 and 2010 in child protection and criminal proceedings.
