Celebrating 35 Years in the Community!

The year 2022 marked a very special year for the Association for Canadian Educational Resources (ACER) as it coincided with a major milestone: 35 years working with schools and communities to help care for the environment.

We can all take pride in ACER’s successes over the years and we hope you will celebrate this very special milestone with us and help us continue on, by making a special donation to ACER’s 35 Years and Growing Campaign. By giving to ACER, you are helping ACER support science-based community climate action. Every tree we plant and monitor together helps keep our communities green, safe and healthy.

Founded in 1987 by Alice Casselman, a high school science teacher in search of Canadian study materials, ACER has focussed since the start on TREES and has planted and monitored thousands over the years, and provided education about their crucial role in the health of our climate and our lives. Hundreds of teachers, students and community volunteers have been inspired by Alice’s vision. For almost three decades ACER programs have helped schools, communities and community organizations understand the importance of biodiversity, environmental stewardship and the need for pro-active climate action; and also to grow the green spaces around them, green spaces that are critical not only for mitigating the impacts of climate change and cleansing our air, but also to our health and well-being. Click here to read more about ACER’s History and Origins Story.
