The Canadian Food Inspection Agency (CFIA) has expanded the regulated area for Hemlock Woolly Adelgid in Ontario.

The new regulated area now includes the Regional Municipality of Niagara, Haldimand County, the City of Hamilton and the Township of Alnwick/Haldimand. This expansion follows detections of HWA outside of the previously regulated area and is part of the CFIA’s ongoing efforts to slow the spread of this destructive insect.

Hemlock materials–including plants for planting, logs, branches and woodchips–as well as any species of firewood, may not be moved outside of the regulated area unless authorized by the CFIA.

Nursery growers who are looking to ship hemlock plants out of regulated areas should refer to Directive D-07-05 and are advised to contact their local CFIA office for guidance and authorization.
