Strategic Plan Renewal

The Severn Sound Environmental Association (SSEA) is renewing its Strategic Plan. We are in the process of compiling results from our community survey that ended October 31, 2023, along with other inputs to the Strategic Plan renewal. When available, process updates will be posted to SSEA Strategic Plan Renewal – SSEA Update.

Thank You to all who participated in the survey and shared their thoughts with us. 


Who we are

The Severn Sound Environmental Association (SSEA) is a Joint Municipal Service Board under the Municipal Act (Section 202). It was originally founded in 1997 as a partnership between federal, provincial and municipal partners to support the completion of the Severn Sound Remedial Action Plan (SSRAP) and to provide a local, community-based environmental office in the Severn Sound watershed. The SSEA provides continuing support to the federal and provincial agencies, but particularly to the local municipalities, to sustain environmental quality and to ensure continued protection through wise stewardship of Severn Sound and its tributaries.

What We Achieved

We have had tremendous success in improving the water quality of Severn Sound. Working with others, we have been successful in having the Severn Sound area delisted as an Area of Concern. Our success in large measure comes from an innovative and collaborative governance model that has, since its inception, focused on partnerships and producing results. This combined with our dedicated team of expert staff has allowed us and our partners, to be champions for Severn Sound. We continue to monitor water quality, fish and habitat and our efforts with others have resulted in extensive tree plantings, land stewardship, sustainability and source water protection initiatives, all designed to leave a lasting and improved environmental legacy for the next generation.

You have the power to help make Severn Sound the most resilient and thriving Great Lakes watershed.
