In 2024, the Canadian Partnership Against Cancer (CPAC) and the Canadian Cancer Society published a Pan-Canadian Cancer Data Strategy to help strengthen how cancer data are collected, shared, and used across Canada.

As part of this work, the Canadian Partnership for Quality Radiotherapy (CPQR), a standing committee of CAPCA, is working with the Canadian Artificial Intelligence & Data in Radiotherapy Alliance (CADRA) and early adopters in Ontario and Nova Scotia to implement two radiation therapy data standards: TG-263 and Operational Ontology for Oncology (O3).  These standards are being adopted to help improve consistency in radiotherapy data and support broader implementation across Canadian jurisdictions.

To assist organizations and teams involved in implementing these standards, we are sharing links to both data standards here:
