Shadow Lake does have some Covid Policies and Protocols in place to ensure the safety of all campers and staff, so please refer to their website for a more thorough understanding of what these policies will look like at camp. Here are a couple of the main policies to be aware of:

  • All staff and campers are required to be fully (3 shots) vaccinated for Covid-19 at least 21 days prior to arriving at Shadow Lake Centre

  • Any campers travelling to camp from outside of Ontario must be in Ontario for 14 days prior to the start of camp

  • If you have come in contact with someone confirmed to have Covid-19, and/or are feeling unwell, we ask that you stay home and do not attempt to attend camp


Since 2007 a great partnership has evolved between the Ontario Prader-Willi Syndrome Association and Shadow Lake Centre, to offer “the greatest camp in the Universe” to individuals ages 16 years and older with Prader-Willi Syndrome.

Each year approximately 35 people with PWS come to Shadow Lake for a week of swimming, fishing, boating, dancing, hiking, making crafts and enjoying dozens of other fun activities.


Shadow Lake Centre is a year round outdoor recreation facility which during the summer months operates residential camping and recreation programs to all ages of people with and intellectual disability. Operating since 1965 the facility is located less than a 45 minute drive from Toronto, has over 300 acres of land, private lake, winterized cabins, modern dining hall, health care Centre, recreation hall and indoor crafts hall and basketball court.

All of our meals have been designed by a dietitian and are kept to 1200 calories. This coupled with morning, afternoon and evening snacks meets the needs of all of our guests and staff. Two dietitians and professional food service staff ensures that portions are controlled and all guests and staff receive the same menu items.


All of the staff are recruited through various Universities and Colleges, many of whom are enrolled in social service courses. After the PWS camp, staff remain with the camp for the entire summer. In addition to staff working as counselors, we have a full time Director, Program Supervisor and Property Manager. Specialty staff include dietitians, lifeguards, Program Instructors, Health Care Workers and Overnight Awake Staff. All staff receive training prior to the camp and many have worked at Shadow Lake for several years.
