I’m currently trying to pull out Canada’s polygon data and separate it by admin levels and when I was using https://download.geofabrik.de/north-america/canada-latest.osm.pbf. I’m unable to find Canada’s Country polygon (osm id of 1428125) in that file. I’m able to find it for greenland and mexico (all at admin level 2). I was wondering if it’s just missing from the current dataset or if I’m missing something.
The thing is I’m getting the country polygons for Greenland and Mexico. Along with trying different data sources for Canada and not getting anything. When I tried using just osmium using what Andy said I saw a part of the polygon, but it has a large hole in it.
