Canada and Greenland have similar geographic features that make health service delivery challenging. We sought to describe geographic access to radiotherapy for indigenous populations in both regions. Methods: We used geospatial analyses to calculate distance and travel-time from indigenous communities in Canada and Greenland to the nearest radiotherapy center. We calculated the proportion of indigenous communities and populations residing within a 1 and 2-hour drive of a radiotherapy center in Canada, and compared the proportion of indigenous versus non-indigenous populations residing within each drive-time area. We calculated the potential distance and travel-time saved if radiotherapy was available in northern Canada (Yellowknife and Iqaluit), and Greenland (Nuuk). Results: Median one-way travel from indigenous communities to nearest radiotherapy center in Canada was 268 km (3 h when considering any transportation mode), and 4111 km (6 h by plane) in Greenland. In Canada, 84% and 68% of indigenous communities were outside a 1 and 2-hour drive from a radiotherapy center, respectively. Only 2% of the total population in Canada resided outside a 2-hour drive from a radiotherapy center. However, indigenous peoples were 336 times more likely to live more than a 2-hour drive away, compared to non-indigenous peoples. Nearly 3 million km and 4000 h of travel could be saved over a 10-year period for patients with newly diagnosed cancers in Canada, and 7 million km and 10,000 h in Greenland, if radiotherapy was available in Yellowknife, Iqaluit and Nuuk. Conclusions: Geography is an important barrier to accessing radiotherapy for indigenous populations in Canada and Greenland. A significant disparity exists between indigenous and non-indigenous peoples in Canada. Geospatial analyses can help highlight disparities in access to inform radiotherapy service planning.
