[Talk-ca] Road name edits in Canada

[Jarek Piórkowski]

Hello Andy,

The mapper has been active in my neighbourhood and I am sad to report
that their edits at least in the Toronto area must be considered
suspect. In https://www.openstreetmap.org/changeset/120101768 they
added a bubble tea shop which was not yet open at the time, and in a
wrong location. The shop opened yesterday at 1660 Queen St W; the
editor added it 8 days ago at 1598 Queen St W, supposedly replacing a
long-empty storefront (which in fact remains empty). I would have to
suspect that the fact that the shop is currently incorrectly listed in
Google Maps at 1600 Queen St W is not a coincidence.
