In Toronto, Ontario from January 17-19 2024, All.Can Canada hosted the Optimizing Cancer Diagnoses in Canada Roundtable. This event consisted of two days of dialogue followed by an ACC Steering Committee meeting. One of these days of dialogue was devoted to Indigenous leadership in health and cancer care, and the other to racialized, LGBTQ+, and other structurally underserved groups. As deliverables following the event, ACC is developing an event report that outlines the learnings from the meetings, which will be shared with all participants and our funding partners; additionally, the learnings from this event will inform our priority-setting for 2024 and beyond.
