The 2024 Wild Parsnip Program is anticipated to start on May 27, 2024, weather permitting. The goal is to reduce the growth of wild parsnip in highly infested areas while ensuring that environmentally sensitive areas and public safety are not adversely impacted. In total, Council has approved $298,000 for this year’s strategy. The 2024 Wild Parsnip Strategy will allow staff to:

  • Continue and expand the application of Clearview and Navius FLEX herbicides to highly
    infested areas;
  • Continue mowing operations, adjusting frequency and timing to best coincide with
    herbicide applications;
  • Re-map infestation areas and levels;
  • Continue the communication and awareness campaign in collaboration with partners in
    Ottawa Public Health (OPH), Ministry of Environment, Conservation and Parks (MECP),
    National Capital Commission (NCC), etc;
  • Provide weekly updates for Councillors on roadside and parkland spraying locations within
    each ward;
  • Prepare communication materials for Councillors to share with residents.

Over 200 locations of parkland and approximately 1200 lane kilometres of roadsides/pathways will be treated this year. The City has significantly increased the number of lane kilometres to be treated this year within existing budgets. Public Works will continue to assess the required resources and budget for spraying operations in future years. Roadside grass-cutting will begin early June and additional herbicide applications may be considered again for the fall season.

To notify the public of the herbicide application, a Ministry of Environment, Conservation, and
Parks (MECP) approved “Notice of Herbicide Use” advertisement will appear in local newspapers
one week prior to the start of spraying. However, given the large number of public access points
for parks, signage will only be posted at main entrance points.

Rural residents who do not wish to have the roadside adjacent to their property sprayed have
been given the option to opt out of the Wild Parsnip Program. Should a resident opt out of the
program, it will become their responsibility to manage any wild parsnip infestation adjacent to their
property, as required by the Weed Control Act of 1990.  For additional information on wild parsnip, please consult the City of Ottawa’s website.
