[Talk-ca] duplicate address data

Hi Gerd,

I'd say that rural addressing is between 10-20% of addresses in Ontario.
Far from a special case.

Yes, I agree that there are some errors, but we can't guarantee that the
Canvec 10 data will be much better, or that some of the older data is
bad just because of its version. Imports work really badly in Canada, as
our source data isn't wonderful and we don't have enough folks on the
ground to verify.

Is there a way to make interpolation names change if the street name is
edited/corrected? Unless this happens, I see these errors as inevitable.
