If anyone was wondering about context, here's the plan:
http://wiki.openstreetmap.org/wiki/Yorkregion_GIS/York_Region_Data_Imports
It has good links to OSM-compatible open data from York Region.
My main problem with the plan — apart from likely wilful data
overwriting — is that they'd clip data to districts. Like we need /more/
arbitrary boundaries to fix in Canada …

Also, the commercial provincial parcels manager gets really possessive
over anything cadastral, even if they didn't collect it or own it. They
have money and lawyers. (Which I sometimes wish they'd direct back to
addressing the quality of the data they sell …)

Most municipalities/regions pay into group orthophoto collection, like
SWOOP in SW Ontario. It's updated every six years or so. It's supplied
to members at cost recovery, but the licensing is restrictive. I did ask
the relevant folks back in 2013 or so if they'd release the obsolete
2006 data if I found hosting (as it was better/newer than most of the
Bing/Yahoo imagery at the time), but I got a no.
cheers,
Stewart
