You are right about the fact that NRCan data is out of date. To have an idea
on how out-of-date it is, the latest version of Canvec has a text file that
gives these specific details for each map (metadata.txt). This file is
included within each Canvec .zip file. See.

There is no automatic import. Someone like you has decided to import the
data some time ago. You can remove it if you wish - but then deleting the
work done by someone else - or better: why don't you update the polygon to
reflect the actual residential area as it is today?

I'm just a casual editor who cleans up things I know first hand in a few
small towns and a small city. So I went to Landmark, Manitoba and saw an
interesting, irregularly shaped out-of-date/incomplete polygon that was
added. I don't recall seeing it when I last visited there several months
ago but who knows.
Residential Area - Source - NRCan-CanVec-7.0
This appears to display a shaded area on the user viewable map.
The problem is that this is very much out of date or incomplete.
Furthermore, for that village/hamlet it's mostly nonsense. Main street,
which is the highway running north/south through Landmark is the
commercial/industrial road through town although there are houses
interspersed among the retail and commercial buildings and feed mill.
Furthermore the residential area goes 1.5 blocks west and a few blocks east.
So it might as well not even exist.
Now judging on my memories of that village/hamlet it is probably at least
ten years out of date.
Does it serve any useful purpose? Is it safe to delete that polygon or
will it come back on some re-import in the future.
