The CFIA Takes Further Action to Slow Emerald Ash Borer

OTTAWA, ONTARIO--(Marketwire - March 25, 2011) - The Canadian Food Inspection Agency (CFIA) is taking further action to slow the spread of the invasive emerald ash borer (EAB) in Canada by increasing the regulated areas. This increase is due to new detections of this beetle in 2010. The CFIA has invoked one ministerial order that includes all regulated areas in Ontario and Quebec.

The ministerial order empowers the CFIA to regulate the movement of all ash tree materials and all firewood from specific areas of Ontario and Quebec. This is important because this is a key way the pest is spread. Those who move these materials from the regulated areas without prior permission from the CFIA could face fines and/or prosecution.

The regulated area for Ottawa and Gatineau has been expanded to include the United Counties of Leeds and Grenville in Ontario, and all of Ottawa.

In southern Ontario, it was determined that the most effective way to regulate is to amalgamate into one regulated area all the cities, counties and municipalities where EAB has been discovered. This will help the movement of ash materials within the regulated area.

The amalgamated regulated area in southern Ontario includes Hamilton, Toronto, the Regional Municipalities of Chatham-Kent, Durham, York, Peel, Halton, Niagara and Waterloo and the Counties of Brant (including the City of Brantford), Elgin, Essex, Haldimand, Huron, Lambton, Middlesex, Norfolk, Oxford, Perth and Wellington.

Regulated areas for Sault Ste. Marie, ON and the regulated area which includes the Municipalities of Carignan, Chambly, Richelieu, Saint-Basile-le-Grand and Saint-Mathias-sur-Richelieu, in Québec remain unchanged.

Although the EAB does not pose a risk to human health, it is a highly destructive beetle that has already killed a large number of ash trees in Ontario and the north eastern United States. It poses a major economic threat to urban and forested areas of North America.

The CFIA will continue to work with its partners and stakeholders towards slowing the spread of EAB.


The emerald ash borer was first discovered in Windsor, Ontario and Detroit, Michigan in 2002. It is believed that this beetle was introduced to North America from eastern Asia in wood packaging material in the early 1990s. It went undetected until its population built up to damaging levels.

Scientists in Canada and the United States have concluded that the emerald ash borer cannot be eradicated. In light of this, the Canadian Food Inspection Agency (CFIA) adopted a "slow-the-spread" management strategy in 2006 and continues to do the following activities across Canada: surveillance, regulation, enforcement, and communications.

To help limit the spread of the emerald ash borer, a ministerial order has been enacted to regulate areas infested by the pest. This will help to restrict the movement of ash tree articles and firewood. When people move these articles, this contributes to the spread of the beetle.

The regulated areas for the emerald ash borer under ministerial order in 2011 are as follows.


  • the cities of Hamilton and Toronto, the regional municipalities of Chatham-Kent, Durham, York, Peel, Halton, Niagara and Waterloo, the counties of Brant (including the City of Brantford), Elgin, Essex, Haldimand, Huron, Lambton, Middlesex, Norfolk, Oxford, Perth and Wellington
  • the city of Sault Ste. Marie


  • the city of Ottawa, the United Counties of Leeds and Grenville in Ontario and the City of Gatineau, Quebec


  • the municipalities of Carignan, Chambly, Richelieu, Saint-Basile-le-Grand and Saint-Mathias-sur-Richelieu

Specifically, ministerial orders prohibit people from moving the following articles outside of an infested area:

  • ash nursery stock,
  • ash trees,
  • ash logs and ash branches,
  • rough ash lumber,
  • wood packaging materials with an ash component as a stand-alone commodity,
  • ash bark,
  • ash wood chips or bark chips, and
  • firewood from all tree species that has not been treated to eliminate the emerald ash borer.

Movement restrictions for the emerald ash borer also apply to vehicles if they are used to transport regulated articles.
