CFIA Takes Regulatory Action to Slow the Spread of Emerald Ash Borer in Southwestern Ontario

OTTAWA, ONTARIO--(Marketwire - July 10, 2009) - The Canadian Food Inspection Agency (CFIA) is taking action to slow the spread of the invasive emerald ash borer (EAB) in Southwestern Ontario. New regulations prohibit the movement of ash tree articles and firewood of all species from specific areas of Southwestern Ontario. Movement of these articles is the primary way the beetle has been spreading to new areas in Ontario. The EAB poses no risk to human or animal health.

New Ministerial Orders have been created to restrict the movement of potentially infested materials from regulated areas.

The previous Ministerial Orders for Elgin County, Middlesex County, Lambton County, Essex County and the municipality of Chatham-Kent have been repealed and these areas are now regulated under one new Ministerial Order.

Huron County is now regulated under another new Ministerial Order. An updated Ministerial Order has also been issued for Norfolk County so that the measures in place are consistent in all regulated areas in Ontario and Quebec.

These boundaries have been determined after consultation with the affected municipalities and stakeholders.

Although the EAB is a destructive beetle that has already killed a large number of ash trees in Ontario and northeastern United States, it does not spread quickly on its own. The CFIA is focusing its efforts on preventing the movement of potentially infested articles such as logs, branches, nursery stock, wood chips, and firewood of all species - to non-infested locations. Those who move these articles from regulated areas without prior permission from the CFIA could face fines and/or prosecution.

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


The Emerald Ash Borer (EAB) was first discovered in Windsor, Ontario and Detroit, Michigan in 2002. It is believed that it was introduced to North America from eastern Asia in wood packing material in the early 1990s, but went undetected until its population built up to damaging levels.

To limit the spread of EAB, Ministerial Orders have been enacted. Ministerial Orders restrict the movement of ash tree articles and firewood since people moving these articles is a major way EAB is spread. Specifically, Ministerial Orders prohibit the movement of ash nursery stock, ash trees, ash logs, ash wood, rough lumber and other wood packaging materials from ash, bark, wood chips or bark chips from ash, and firewood from all tree species that has not been treated to eliminate EAB. Ministerial Orders for EAB also extend to vehicles that are used to carry these items.
