In this inspiring episode, we sit down with Krissan Veerasingam — lifelong Scarborough resident, community activist, and co-founder of the Scarborough Environmental Association (SEA). Krissan shares his journey from grassroots political canvassing with Progress Toronto to launching SEA, a local force for equitable environmental action in Toronto’s east end.
Discover how his upbringing shaped his passion for repair culture, how SEA is using bike repair and pollinator planting events to bring people together, and why redefining “environment” is key to community building.
Krissan’s story is a powerful reminder that meaningful change often starts right at home. Tune in to hear how one resident’s vision is transforming Scarborough into a model of grassroots leadership, sustainability, and community care.
Restoring Toronto’s natural areas is more urgent than ever, and in this episode, we spotlight the volunteer-powered work of Toronto Nature Stewards as they protect and revitalize one of North America’s largest urban green spaces.
Spanning more than 11,000 hectares—an area comparable to the size of Paris—Toronto’s ravines support the well-being of over three million people, safeguard biodiversity, regulate critical water and nutrient cycles, and mitigate flooding and erosion risks. Unfortunately, these vital ecosystems face severe threats from invasive species, climate change, development, and litter.
Join us for an in-depth conversation on how Toronto Nature Stewards combats these challenges by removing harmful plants, planting native species, clearing trash, and raising community awareness about the importance of ecological balance. Discover how hundreds of passionate volunteers unite across 42 sites to nurture healthy, self-sustaining urban habitats for current and future generations. Learn how you, too, can contribute to preserving Toronto’s ravines and embrace an active role in urban conservation. Tune in for a powerful reminder that every individual can make an impact, one natural area at a time.
In episode 5 of the podcast, we speak with Rhonda from Toronto Urban Growers, a network of local food producers dedicated to scaling urban agriculture in Toronto. Rhonda shares her journey from social work to urban farming, emphasizing the community-building power of growing food.
She discusses the challenges and successes of transforming public spaces, like Flemo Farms in Flemington Park, into thriving community gardens and farms. The conversation highlights the importance of collaboration, policy advocacy, and the vision for a more inclusive, sustainable food system. Rhonda also touches on the broader environmental and cultural impact of urban farming, including the integration of Indigenous, Black, and queer farmers into the movement. With a focus on hands-on community engagement, the episode encourages listeners to get involved, support local agriculture, and reimagine how urban spaces can be used to feed both the body and the soul.
We are reaching your ears through our official podcast, Green Hearts in Action hosted by Dominik Haake! This month we interviewed Dorte Windmüller, working at Cliffcrest Butterflyway. Their goal is to help increase the numbers and biodiversity of bee, bird, and butterfly populations through gardening!
Our pollinator population is in trouble - because of their population decline, so are our birds. With restorative garden practices and the focus on native powerhouse plants, gardeners can create food and an environment that supports the various life stages of our insects and birds. Combined, gardeners have an enormous, untapped impact on restoring large-scale biodiversity and reducing our carbon footprint.
This month we interviewed Rochelle Byrne, working at A Greener Future. Their goal is to preserve the environment through litter cleanups, education and events.
A Greener Future is an environmental non-profit dedicated to leading the effort in sustaining a clean and healthy environment. By bringing together a community of volunteers and environmental stewards, they facilitate programs that eliminate waste from the environment. As education is at the centre of what they do, they inspire change through a variety of learning opportunities. Their programs raise awareness about plastic pollution in the Great Lakes Region, and detailed data collection sheds light on the most common items that are found during litter cleanups.
Tim Grant is a green heart in action volunteering for Harbord Village Residents Association and spearheading exciting projects like the Net Zero Carbon Project.
Grant is an inspiring fellow neighbor in Toronto working on reducing his community's greenhouse gas emissions. His efforts are enhanced by his ability to drum up enthusiasm and create a snowball effect by utilizing the power of neighborhood alchemy. This episode was recorded while I met Tim in his neighborhood and walked around his community. He points out houses that have already taken action to get off gas and become more energy-efficient through retrofitting.
Dive into the heart of Toronto’s green movement with the inaugural episode of the GNN Green Hearts in Action Podcast.
