Deadline to Apply: March 1, 2024

An immersive research experience

KSR’s diverse range of ecosystems and facilities attracts researchers and visitors from many different fields and disciplines for hands-on experience with ecological systems that no university campus can offer. Researchers at KSR study questions related to ecology and evolution, conservation practices, climate change, aviation, data and signal transmission, and more. 

A classroom like no other

Every year, hundreds of students and postdoctoral fellows come to KSR to work with our scientists. KSR’s unique diversity of habitats and species within a mosaic of wetland and forests offer precious opportunities to understand the profound impact of global change and expand our understanding of the natural world.

Wake up in nature

KSR has a variety of year-round shared and private accommodations for researchers, students, and visiting groups. Keep in mind that it’s good to reserve early in the season.

Explore KSR

With miles of trails through pristine wilderness, KSR offers unlimited opportunities for hiking, photography, birdwatching, and nature study.

Young people arrive at KSR for the Experimental Ecology course as science students. They leave as scientists.

Dr. Arthur Weis, University of Toronto

My time as a graduate student researcher at KSR was a formative experience that helped me develop into an independent scientist. KSR made it possible to perform long term artificial pond experiments that were a main focus of my PhD, and my many interactions with other students and faculty at KSR engaged me in a range of topics in ecology and evolution

Dr. Stephen DeLisle, PhD from the University of Toronto, St. George Campus

From observational studies to large-scale multi-year experiments, KSR has played a pivotal role in my research program for over 20 years. KSR has allowed me to train the next generation of scientists in natural history and field research, including undergraduate students, graduate students and postdoctoral fellows. I love the family friendly atmosphere of KSR. My entire family has stayed at KSR for up to a month at a time, which has made for a fun work-life balance.

Dr. Marc Johnson, The University of Toronto Mississauga Department of Biology

A new development at KSR

A new multipurpose building that will greatly expand our operations is under construction. It will include sleeping accommodations, a communal kitchen, social gathering spaces, teaching and conference spaces, and more. This project has been made possible through generous donor support to the University of Toronto.

Construction on the main building is progressing quickly. Stay tuned for updates about this exciting project that will expand KSR’s horizons. During construction, the condition of our main roadway may be affected. For any questions or concerns please contact the Station Manager.
