 From a legal perspective, any tag can be removed at any time. This 
doesn't mean they *should* 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.

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.
