Dáire works with HEN staff on developing gardening skills and providing food and garden related programming, helping the community grow together.

Elin Marley

Halton Food - Region Manager North Halton

Elin has always enjoyed exploring the outdoors and started developing a passion for environmental issues thanks largely to her grade 1 teacher and her elementary school Nature Club. After studying anthropology at the University of Guelph, Elin found that food was a perfect way to tie together her interests in cultural studies and environmental issues. Working on an organic farm in 2009, Elin learned a ton about growing food and was also reminded of how real carrots taste! Since 2010, Elin has worked as a School Garden Educator, teaching elementary school students about growing food, where our food comes from, and getting hands-on experiences in the natural world.

One of Elin's favourite things about school and community gardens is the community connection that grows around it. She believes gardening ignites curiosity from people in all age groups, across cultures and languages. Elin also enjoys cooking, hiking, cross-country skiing and folk dancing.

Helen Stephenson

Halton Food Program Manager

With nearly 200 square feet of vegetable gardens in her backyard, a certificate in Horticulture from the University of Guelph, and a degree in Biology from the University of Waterloo, Helen has extensive knowledge in sustainable urban agriculture. Helen joined Halton Food Council, now Halton Food, in 2017 but had been leading the Junior Gardening Program through the Oakville Horticultural Society for many years before that. Her program included lessons on vegetable growing, weeding, watering, harvesting as well as talks by experts on soil, bugs, milkweed and bees. She has also spent many years independently studying, identifying, and growing species native to the Carolinian Region. She is committed to remaining up-to-date and involved with current trends in horticulture. When she isn’t gardening, Helen is actively involved with the sport of curling.

Iga Balazy

Volunteer and Outreach Coordinator

Shortly after graduating from the University of Waterloo with a Bachelor of Social Work degree, Iga was confident she wanted to pursue a career in food justice. She was introduced to Halton Environmental Network (HEN) while volunteering with Kerr Street Mission, one of HEN’s many community partners.

In her role as a Volunteer and Outreach Coordinator, Iga spends most of her time out in the community, whether it be getting her hands dirty in a local community garden or connecting with local schools and places of worship.

She has a strong interest in the food system and believes it is critical for regions to advance sustainable, place-based, food-growing practices in our increasingly urbanized communities.
