Weed Complaints

weed complaints

The County of Lennox & Addington administers the Weed Control Act within the Township of Stone Mills.  However, responsibility for this Act is limited to:

  • whether the weeds in question are on the list of noxious weeds; and
  • if the weeds are a threat to agriculture.

If the weeds are noxious and are a threat to agriculture, and the complaint is from a person involved in agriculture, the complaint will be dealt with under the Act, by the County.  If the weeds are located in a residential area, park area, on un-maintained lots, and roadsides and are not a threat to agriculture, the County will not address the complaint under the Weed Control Act.  These complaints will be investigated pursuant to the lot maintenance bylaw and in accordance with roadside maintenance policies of the Township.  Roadside mowing complaints should be directed to Public Works department for the Township of Stone Mills.

Also, management information has been developed by The County of Lennox and Addington respecting weed control which the reader may find useful if this weed exists on your lands.
