What we're about

Cambridge City Green is a small group of volunteers that leverage dozens of other groups and thousands of individuals in Cambridge, Ontario to "be the change they want to see in the world." CCG is composed of volunteers who develop, host, and support community environmental projects like tree planting through the Cambridge Stewardship project, litter clean ups through the Community Clean Up Day, and an annual event (workshops, movie nights, etc.). CCG has been around since 1993 and is an action-oriented subcommittee of the Cambridge Environmental Advisory Committee of Council. Cambridge City Green initiated the Cambridge Stewardship project in 2007 with seven founding partners and one planting site. In the past 9 years (2007-2015), over 75+ groups and 3,000+ volunteers have planted over 10,000 indigenous trees, shrubs, and wildflowers at 23 sites during 81 planting events across Cambridge. Every year 3000-5000 individual volunteers and 50+ groups help take care of litter through the Cambridge Community Clean Up. Each year we plan an annual event, invite keynote speakers and local organizations doing interesting things, with an objective of positive change (rather than sitting around and complaining and blaming) and what YOU can do tommorrow. If you want to join Cambridge City Green in planning community projects, or starting new ones, or just want to participate in one of the events let us know.

Seedy Saturday!


Saturday, March 5th

768 Blair Rd, Cambridge

Join us Saturday March 5th from 10am to noon for a free event where you can swap and exchange seeds! You’ll meet fellow gardeners and find exciting seed varieties that other seed savers are sharing. We encourage attendance whether you are a first-time gardener or a seasoned expert.
Doors will be open from 10:00 a.m until noon.

Please bring small, well-marked packets of vegetable, herb, and native pollinator seeds. If you don’t have any seeds to contribute to the exchange, come anyway! Some people will simply share their seeds and the interesting stories that come with them.

If you have lots of seeds to share, please consider a seed donation to the Food Bank Garden project at rare as well as the Seed Libraries at Idea Exchange Preston and the Cambridge Food Bank.

Our community partners at Idea Exchange Preston, Seeds of Diversity Canada, and the Cambridge Food Bank will be on site to share info about their ongoing and upcoming projects.

Digital Clean Up Day

Needs a location

Here is an activity that we invite you to do at home for yourself and the environment.

In the digital world, similar to the environment, there is a huge amount of trash. Unnecessary emails, files, apps, duplicates of photos and videos are all digital waste. This digital trash creates digital pollution that continues to consume energy even when we have forgotten it. Digital trash sits in the backups on servers that provide us with cloud service and continue consuming electricity.

Each year the internet and its supporting systems produce 900 million tons of CO2. Some studies estimate that in a decade the internet network will consume 20 percent of the world’s total energy*.

If we delete all unnecessary files, apps, photos and videos, we are not just saving a huge amount of CO2 but we are also extending the life of our gadgets, feel more balanced, and we take control over our lives, forge new digital habits, and we will be more efficient and satisfied.
Sounds like a win-win!

Cut down your CO2 share, join the Digital Cleanup Day movement,
from 1st of October 2021 to 20th March 2022!

See this website for more details on what you can do.
