As an Intern/Co‑op Biologist, you will work alongside experienced biologists and environmental professionals to support a variety of ecological projects throughout Ontario and the Greater Toronto Area (GTA). You will contribute to field surveys, data collection, technical reporting, and environmental planning initiatives while developing practical skills in environmental consulting and stewardship. This role offers exposure to multidisciplinary project teams and the opportunity to build a strong foundation in applied ecology, regulatory processes, and environmental assessment work.

Candidates should have a strong interest in terrestrial and aquatic ecology and environmental consulting, along with excellent organizational, communication, and technical writing skills. The successful candidate will be able to work effectively both independently and as part of a collaborative, multidisciplinary team.
