She returned to Brockville during the summers between university to work at the dive shop and to continue advancing her dive education. In the last several years she has pursued technical diving; receiving certifications for sidemount, advanced nitrox, decompression procedures, rebreather and intro to cave. She has also taken courses in freediving and underwater archaeology.

Diane Morrell

Director at Large

Diane joined the Freedom at Depth Canada Board in April 2019. Despite sustaining a spinal cord injury in 1989 while tobogganing, Diane has led an active life as a spouse, mother, volunteer, and has successful career and participates in various sports.

Diane began diving in 2009 with Freedom at Depth and has continued to pursue additional dive education including, rescue diver, cavern, intro to cave, advanced nitrox, side-mount, and freediving. Although Diane was not able to be certified as a rescue diver due to the inability to remove an injured diver from the water, she was determined to take the course to gain new diving skills. Certification was not her primary goal with this course, but to learn more about safety and to become a better diver through this experience.
As a volunteer, Diane has co-founded two charitable organizations in her home community of Sault Ste. Marie. She is still an active Board member of No Limits Adaptive Ski Association (adaptive downhill skiing). She is also an active downhill skier.
Diane works as Accessibility Coordinator for the Corporation of the City of Sault Ste. Marie.

Daryl Rock


In 1983, while attending College Militaire Royale de St Jean (CMR), Daryl Rock sustained a spinal cord injury that resulted in him using a wheelchair ever since. Following this injury Daryl moved to Ottawa where he returned to university, completed an undergraduate degree and an MA in Public Administration before beginning a career in the Canadian federal public service.

Not letting the wheelchair slow him down, Daryl developed a passion for adventure travel, visiting dozens of countries around the world. While many of the places he visited were not wheelchair accessible, Daryl discovered that with the right attitude, a little creativity and support of others, almost anything was possible. While visiting Australia in 1990, Daryl had an opportunity to scuba dive the Great Barrier Reef. This experience sparked a lifelong passion for diving and led to him becoming involved in the founding of Freedom at Depth Canada.

Now a retired senior executive of the Canadian Federal Public Service, Daryl divides his time between travelling and community service. In addition to being Chair and co-founder of Freedom at Depth Canada, he is currently a member of the Board of directors of the Canadian Foundation for Economic Education and iStory, a national aboriginal education organization. He is also a Director at West Wind Associates, a member of the National Capital Commission’s Accessibility Advisory Committee and member of the Sovereign Order of St. John of Jerusalem.

He is the past-Chair of the Rick Hansen Institute (a global research institute committed to addressing spinal cord injury issues), and past-Chair of the Ontario Neurotrauma Foundation. Over the years he sat on numerous other board and government committees. He is a recognized expert in social development and public policy. He has presented at conferences throughout North America. His work has been profiled in the Wall Street Journal and Forbes Magazine.
He holds a Masters degree in Public Administration, and a BA in Political Science both from Carleton University, as well as a CEGEP certificate in engineering from College Militaire Royale de St. Jean.
Originally from Halifax, N.S. he currently resides in Ottawa with his wife Melanie.

Mark Dumalski


Mr. Dumalski is a Chartered Professional Accountant and one of the first visually impaired individuals in Canada to become certified as a recreational Open Water Scuba diver. Following his recreational certification in 2002, Mr. Dumalski obtained his Advanced level HSA certification with Freedom at Depth in 2008. In the years since his introduction to the sport, Mr. Dumalski has continued to demonstrate that conventional expectations concerning the visually impaired community and scuba diving do not always apply. With minimal assistance from sighted divers, he has completed countless dives, independently exploring several ship wrecks in the St. Lawrence River, fresh water caverns in Northern Florida, and coral reefs in the South Pacific.

From his career as an international tax partner with Deloitte LLP, to his numerous pastimes including scuba diving, curling, and downhill skiing, Mr. Dumalski’s life is full of examples which demonstrate his firm belief that persons with disabilities are capable of achieving any goal, and accomplishing any task, regardless of perceived limitations.
