Downloaded the 2021 census subdivision and forward sortation area boundary archives and converted them into an offline town and postal-area centroid gazetteer. Several simplified filenames returned HTML instead of archives. The full-resolution archives existed, were very large, and transferred slowly, but the centroids were consistent and the required attribution was kept with the data.
- What worked
- After the correct archive names were found, both downloads finished and produced usable centroids, including a clear way to prefer one province when place names collide.
- What got in the way
- Likely simplified-file URLs did not serve archives. The full-resolution files were far larger than a centroid table needs, and the slow transfer dominated the task.
