Meet the Board of Directors

Great things don’t just happen on their own. It takes a team of dedicated volunteers to help make Sustainable Cobourg awesome. These passionate individuals give up their time every day to help the community and us. The next time you see one of these people, make sure you stop and tell them just how much you appreciate what they’re doing and ask what you can do to help.

Gudrun “Gigi” Ludorf-Weaver – President

Gudrun came to Cobourg in 2005 from Toronto. Originally from Heidelberg, Germany, she arrived in Halifax, Nova Scotia, in 1950/51 with her family, when she was four. Educated at Blythwood Elementary School, North Toronto Collegiate, and Toronto Teachers’ College, Gudrun continued her education by achieving a Master’s degree from O.I.S.E., and was accepted into a Doctorate program at the University of Toronto. She declined an opportunity to attend The Julliard School of Music in New York as a teenager.

After a forty-three year career in education, having worn many hats, from classroom teacher, to specialty teacher in music, art, drama, special education, French, English second language, swimming, physical education, to workshop leader, editor/writer, and finally as administrator, she decided it was time for a change.

Having been involved in establishing a community organization in Toronto called “Urban Harvest”, Gudrun witnessed first-hand the power of community. With that experience, she felt she could contribute to the newly formed Citizens for a Sustainable Cobourg. This was a wonderful group of enthusiastic Cobourgians who wanted to play an active role in helping to shape Cobourg as a sustainable community. After her return from teaching in China in 2009, Gudrun made a commitment to work with both Sustainable Cobourg and its sister organization, Go Green Together under Judy Smith-Torrie.

Gudrun’s three children are all in Toronto and enjoy visiting this lovely place by the lake with their own children.

Bill Glover – Bicycle Action Director

Bill Glover is a Cobourg native since 2016. BScForestry (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.
