City of Thunder Bay

Thunder Bay, ON

Bill Mauro


Pledge Summary

Thunder Bay is the largest city in Northwestern Ontario with a population of roughly 108,000. Situated along the north shore of Lake Superior, the largest of the Great Lakes, Thunder Bay is nestled on the edge of the wild boreal forest and surrounded by stunning natural habitat. Mayor Mauro is proud to sign the Mayors' Monarch Pledge to strengthen Thunder Bay's ongoing commitment to environmental sustainability through the EarthCare Sustainability Plan. With over 100 parks and parkettes, and more than 32km of paved recreational trails, Thunder Bay recognizes the importance of urban nature. With the help of the dedicated volunteers from the Thunder Bay Urban Greenscapes Volunteer Group, we will continue to work towards conservation of the Monarch Butterfly and other pollinators by educating and empowering citizens, engaging in community conservation efforts, and encouraging the planting of milkweed throughout our community. We can all work together to protect, enhance, and create essential pollinator habitat.

Community Spotlight

Action Items Committed for 2022

Communications and Convening

  • Launch or maintain a public communication effort to encourage residents to plant monarch gardens at their homes or in their neighborhoods. (If you have community members who speak a language other than English, we encourage you to also communicate in that language; Champion Pledges must communicate in that language.)
  • Engage with community garden groups and urge them to plant native milkweeds and nectar-producing plants.
  • Engage with city parks and recreation, public works, sustainability, and other relevant staff to identify opportunities to revise and maintain mowing programs and milkweed / native nectar plant planting programs.
  • Create a community art project to enhance and promote monarch and pollinator conservation as well as cultural awareness and recognition.

Program and Demonstration Gardens

  • Host or support a native seed or plant sale, giveaway or swap.
  • Facilitate or support a milkweed seed collection and propagation effort.
  • Plant or maintain a monarch and pollinator-friendly demonstration garden at City Hall or another prominent or culturally significant community location.
  • Plant milkweed and pollinator-friendly native nectar plants along roadsides, medians, or public rights-of-way.
  • Initiate or support community science (or citizen science) efforts that help monitor monarch migration and health.
  • Add or maintain native milkweed and nectar-producing plants in gardens in the community.
  • Launch, expand, or continue an invasive species removal program that will support the re-establishment of native habitat for monarch butterflies and other pollinators.

Systems Change

  • Change weed or mowing ordinances to allow for native prairie and plant habitats.
