Just a quick note that I haven’t seen in this thread yet. No map can be finished, and no map can ever be exactly true - something will always become out of date. The same is true of any data sources. Canvec is certainly somewhat outdated. How up to date is the aerial imagery, though? I doubt the whole north is being overflown and photographed every other year. Most OSM editing tools don’t make it easy to find out the date of the imagery being used, either.
