Canada's rare genetic diseases present a unique challenge, but with the right infrastructure and vision, the country can create a transformative learning health ecosystem. The key to unlocking this potential lies in data infrastructure and the ability to share and interpret genomic data effectively. While Canada has made significant strides in developing foundational components, such as innovative programs and infrastructure, the current funding cycles and limited budgets hinder long-term sustainability and integration. This fragmentation presents an opportunity for Canada to create a more integrated, equitable, and efficient system for those living with rare diseases.
An accurate diagnosis of rare genetic diseases relies on data sharing and discovery research. The past 15 years have seen a revolution in clinical diagnosis through genomic DNA sequencing, but interpreting DNA variants requires access to large-scale datasets. In Canada, the All for One Data Sharing Agreement has enabled responsible sharing of clinically generated genomic and health data between diagnostic laboratories. This is further supported by the Canadian Open Genetics Repository and the Silent Genome's Indigenous Background Variant Library, which are crucial for accurate genomic diagnosis. However, these efforts are not enough, and Canada needs to establish a national system that supports interconnected, sustainable data sharing across healthcare and research.
Canada has the pieces but not yet a system. A federated approach may be the solution, where data remains within trusted institutions while becoming discoverable, comparable, and usable through shared standards, governance, and infrastructure. This aligns with Canada's Expert Advisory Group on the Pan-Canadian Health Data Strategy, which calls for stronger health data foundations. To make responsible data sharing routine, Canada needs federal leadership, recognition and funding of data sharing as core diagnostic infrastructure, national standards for RD testing and data, and patient, family, and community partnership in governance.
The opportunity for Canada is significant. Every test, every unsolved case, every diagnosis, and every patient experience can help strengthen the system for the next person. However, this will only happen if data sharing is treated as core health infrastructure, supported by sustained investment, policy alignment, and coordination across jurisdictions and sectors. Canada has the potential to create a more integrated and effective system for managing rare diseases, and with the right vision and investment, it can become a global leader in this field.
