Gudrun (Gigi) Ludorf-Weaver has a passion for doing things better and smarter and that means doing anything with the lens of Sustainability. She has helped the organization to grow in the last 15 years with experienced, professional and dedicated volunteers leading the charge on many fronts.

An educator by profession, culminating as a Toronto Board administrator, and also wearing many hats from editor of Toronto Teachers’ Federation newspaper “Role Call’, to swimming instructor at Hillcrest School, to Primary Specialist Kindergarten teacher, to French Second Language as well as English Second Language teacher, and teacher for every grade enjoying each and every experience.
Mother of 3 delightful ‘bundles of joy’ and grandmother (Oma) to 6 more!

She has been a resident of Cobourg since 2005 and looks forward to many more years helping this beautiful Town commit to the 3 elements in the architecture of Sustainability; environmental stewardship, social responsibility and economic resilience not just for us now but for the future generations to come.

Lorna Miller


Lorna is an accomplished Administrator with years of experience within progressive and environmentally conscious organizations. A keen social and community awareness was acquired through various work experiences within strong long standing Canadian corporate companies, who consistently demonstrated their environmental and social commitments. Lorna benefited from working on a national scale, and in that capacity, grew to understand and appreciate the diverse and fragile space we hold, and the importance of sustainability. She embraces a continuous learning culture and believes learning and contributing go hand in hand. She is an enduring volunteer, for which examples are the Canadian Diabetes Association and the Northumberland Orchestra and Choir. She moved to Cobourg in the late 1990’s, from Toronto. When not active in community events, or travelling, she loves to spend time on puzzles, listening to music or simply being in the garden.

Tovan Lew


Tovan is a third-year student at Trent University studying Biomedical Science out of Cobourg. Having gained experience participating in the Environment club, Interact club and for the Fair Share Food Bank throughout high school, he is committed to creating spaces for youth to participate in bettering our community and planet. As a novice beekeeper, he learned the important role pollinators play in contributing to our environment’s well-being and grew to understand the significance of protecting this delicate balance through sustainability.

In addition to his role with Sustainable Cobourg, he is an ongoing volunteer with the Hospital Elder Life Program at the Northumberland Hills Hospital, an executive member of the Undergraduate Biology Society at Trent, and an alumnus of the Summer Scholars Program at McMaster University where he contributed to research on T-Cell Immunotherapy.

He is driven toward engaging everyone in the community through accessibility and inclusion. Through a monthly ‘Sustainable Youth of the Month’ spotlight, Tovan showcases local everyday actions we can all take to work towards sustainability, which can be found on SC socials. Tovan is the director of social media and warmly invites new ideas and perspectives to share!

Bill Glover

Bicycle Action Director

Bill Glover is a Cobourg native since 2016. BSc Forestry (Wood Science) from U of Toronto. Worked for several wood industry associations over 13 years before joining Canadian Standards Association to manage construction materials and engineering design standards committees. Leaving CSA, I operated a one-person home repair business in Toronto. Moved to escape Toronto and retire close to my daughter and her family, and because Northumberland is an interesting and attractive place to live. Returned to cycling after arriving in Cobourg, joined the Northumberland Hills Cycle Club from which I was introduced to the Bicycle Action Committee and then the Cobourg Transpotation Advisory Committee. I became Co-Chair of the BAC in summer of 2021. My interest in cycling and this committee work is to encourage the completion of a fully connected cycling network, to afford cyclists of all ages the option of safe commuting and healthy enjoyment of recreational cycling within our community. Had the dice fallen differently at university, I might have ended up working in watershed management.

Did You Know?

Packed into standard shipping containers and placed end-to-end, municipal solid waste generated in one year would wrap around the globe 25 times. This is unsustainable! What is your community doing to target waste reduction? -

Adopting sustainable practices, whether large or small, can have significant impacts in the long run. If every office worker in the United Kingdom used one less staple a day by using a reusable paper clip, 120 tonnes of steel would be saved in one year.

So far in 2022, Depave Paradise has depaved 15 asphalt pavements! Since 2012 this group has completed 80 projects across 32 Canadian cities covering 76,384 square metres of unused paved surfaces into beautiful community green spaces with native grasses, flowers and trees. What an amazing sustainable action to capture carbon, a Greenhouse gas, and create a welcoming ecological ‘paradise’ for our monarchs and bees and of course, for us. Well done. This is a project of Green Communities Canada.

In 1993, the Convention on Biological Diversity put the precautionary principle to work.

In 1987, the Brundtland Report consolidated decades of work on sustainable development.

The First World Climate Conference happened in 1979 and opened up the science of climate change.
