About Us

The Child and Nature Alliance of Canada fosters meaningful connections with the outdoors for children and youth. We believe that all children and youth should have the opportunity to play and learn in forests, parks, meadows, and mud puddles.
We work to connect children and youth with nature through policy, research, and practice.
We aim to have a deep impact on families and communities across the country. This is woven into all our key initiatives including Forest School Canada (FSC), the major educational arm of CNAC; the Ottawa Forest and Nature School, our demonstration school and in-forest home of CNAC; the Natural Leader Alliance (NLA); and our research and policy development efforts.

Our People

Passionate about the potential of nature to educate and inspire children and youth, our staff team and board of directors play a vital role in our work. Learn more about the team and how to get in touch with us below.

Hannah Clarke


Hannah grew up in a small town outside Toronto where her interest in all things nature sparked! The keen desire to explore outside led her to a wide range of jobs. She worked at an outdoor camp as the Drama and Musical Theatre counsellor for 6 years, then took on the role of Education Assistant at the Nottawasaga Centre for Conservation in her hometown. She previously worked on a berry farm as well, learning the intricacies of plant growth and harvesting. In addition to her interest of being outside, she thoroughly enjoys engaging with young minds in a variety of settings. She worked as “scientist” for Scientists in Schools (with the public board) as well as a Preschool Educator at a Child Care Centre. These dynamic experiences led to her pursuit of a Bachelor of Education at the University of Ottawa, wherein she completed a placement at the Ottawa Forest and Nature School. It was during her placement that she discovered Forest School as a space that fosters joy, curiosity, rich learning opportunities, and exploration – a space where magic exists. And a site wherein children create, dream, play and BE! Each day she is present, the children and fellow educators remind her, in one way or another, to reconnect, refresh and RESPECT this beautiful world we live in.
