The tags don't matter; attribution is in the <b>© OpenStreetMap

tags if we modify data on the ground, or add in our own additional

From a legal perspective, any tag can be removed at any time. This
doesn't mean they <b>should</b> be removed. The question you want
to ask is, what is more helpful to other mappers? If you've changed
enough to make it misleading to say "This is NRCan data", you should
change the source tag.<br>
<br>
I always remove the attribution tag, as it duplicates the
information in the source tag. There's other tags left-over from the
import that I normally removed after a minimal inspection, because
they're generally wrong, misleading, or useless.<br>
