COMP Winter School 2027
January 27-30, 2027
Pillar and Post, Niagara-on-the-Lake, ON
Join us for three days of focused, interprofessional learning at the 2027 COMP Winter School: Reirradiation in Modern Radiation Oncology—Clinical, Technical, and Radiobiological Considerations. This year’s program brings together medical physicists, radiation oncologists, radiation therapists, and dosimetrists to explore the global state of reirradiation, evaluate emerging commercial technologies, and chart a coordinated Canadian path forward.
The Winter School combines keynote perspectives, site‑specific deep dives, industry‑focused plenaries, Canadian initiatives, and a national stakeholder dialogue ultimately culminating in a shared strategy for advancing reirradiation practice and research across Canada
