I have checked for the origin of the problem with old documentation about the Canvec2osm process. It seems the proprietary translator (FME) used to convert the data to OSM may have generated the problem.
However, since the same translator was used for all the polygons, the problem should also appear on water bodies, etc. The problem may have been related to the complexity of the polygons to convert. I also found that JOSM had similar problems with tag transfers a few years ago (1). Maybe some of the problems found result from merging nearby wooded areas?

I think it may still be an issue with later versions.
