Andrew Hyett is a geologist and rock mechanics specialist with decades of experience at the intersection of subsurface engineering and applied research. He held a research position in the Department of Mining Engineering at Queen’s University, focusing on the mechanical behaviour of rock and ground support systems. He later founded YieldPoint Inc., a Kingston-based instrumentation company developing fibre-optic sensing technology for monitoring deformation in rock, soil, and civil infrastructure — the kind of monitoring that underpins safe design of tunnels, foundations, and major linear infrastructure. He is now retired.

Lindsay Davidson is a Fellow of the Royal College of Surgeons of Canada (Orthopaedic Surgery) and Professor Emerita at Queen’s University, where she also served as Chair of Teaching and Learning. Her academic career combined clinical practice with a sustained focus on evidence-based research methodology and the rigorous evaluation of complex systems — skills as applicable to the analysis of public policy and infrastructure governance as to medicine.

Liz Crawford is a retired industrial designer, professional gardener, and amateur naturalist. She lives in Toronto and visits frequently the Frontenac Arch Biosphere, where she has hiked extensively through largely wild areas adjoining the Cataraqui and Rideau trails. In her gardening work, she regularly addresses invasive species and has read extensively on best management practices. She is completing the Pollinator Stewardship Program with the Pollinator Partnership, and has volunteered with the Turtle Protectors and City of Toronto Park Stewards. Her contributions bring direct field knowledge of the Frontenac Arch landscape and hands-on experience with invasive species management.

Edward (Ted) Darby brings over forty years of experience as a healthcare leader, having served in senior executive positions at several of Canada’s most distinguished health institutions, including Sunnybrook Health Sciences Centre, North York General Hospital, and Kingston Health Sciences Centre. He holds a Bachelor of Science and a Master of Health Science from the University of Toronto. His career has been defined by the governance and management of large, complex organisations operating under conditions of constrained resources, competing stakeholder interests, and sustained public accountability.

Kurt Hennige is a shrike biologist with direct, hands-on experience monitoring and supporting the recovery of the Eastern Loggerhead Shrike in the Napanee Plain — one of only two remaining regular breeding locations for the species in Canada. He serves as Habitat Stewardship and Recovery Action Group Coordinator for the Napanee Plain and is a Director of the Lennox and Addington Stewardship Council. His standing as an eBird Reviewer for three regions in Eastern Ontario reflects a level of ornithological expertise recognised by the Cornell Lab of Ornithology.

Steven Moore is a retired Assistant Professor who held appointments in both the Smith School of Business and the School of Environmental Studies at Queen’s University, teaching at the intersection of sustainability, ecological economics, and business and environmental strategy. He was voted Student’s Choice Professor of the Year in Environmental Studies for both Sustainability and Ecological Economics. He has run an off-grid organic farm on solar power, designed and built an earth-sheltered home, and owns and operates Moore Partners, a 20 kW microFIT solar photovoltaic energy producer.

Susan Moore is a writer and editor with more than twenty years of experience working with regional community groups across Eastern Ontario, translating complex issues into clear, accessible language for general audiences. She serves as Secretary of the Lennox and Addington Stewardship Council and as President of Friends of Salmon River — a community organisation dedicated to the protection and restoration of the Salmon River watershed, one of the waterways directly within the footprint of the ALTO southern corridor.

Lawrence O’Keeffe is the Founder and Past Chair of Friends of the Napanee River, a community organisation dedicated to the protection, restoration, and advocacy for the Napanee River watershed — the waterway at the centre of the southern corridor environmental risk assessment. He has served as a Past Director with the Lennox and Addington Stewardship Council and brings fifteen years of experience in international consulting and project management to this initiative.

Rena Upitis is a retired professor of education and environmental studies at Queen’s University, and a Fellow of the Royal Society of Canada — one of the country’s highest academic honours. She is a Founding Director of Wintergreen Studios, an off-grid environmental arts centre in South Frontenac, located directly within the area affected by the proposed ALTO southern corridor. Her contributions bring first-hand knowledge of the communities and landscapes at stake, alongside an academic career dedicated to evidence-informed inquiry and public engagement.
