On November 1, 2007, a staff member from the Ontario Ministry of Natural Resources detected trees suspected to be infested by the Emerald Ash Borer (EAB) in a residential area of Toronto, Ontario, and contacted the Canadian Food Inspection Agency (CFIA). CFIA inspectors collected samples and on November 6, 2007, CFIA entomologists confirmed that the samples were EAB. This is the first infestation of EAB to be detected in Toronto, Ontario. The CFIA is investigating the origin of the infestation, and will continue surveying to determine the range of the infestation. Regulatory actions are pending for this latest find.

There are currently five areas in South-western Ontario regulated by Ministerial Order for EAB: Essex County, Municipality of Chatham-Kent, Lambton County, Elgin County, and Middlesex County. A small region of Norfolk County, in which EAB was detected in October, is also under official quarantine.

Under IPPC Standards (e.g., ISPM No. 8), EAB is considered present (only in some areas of Ontario) and subject to official control in Canada.  For more information on the EAB, please visit the CFIA website at
