Does anyone know where I can find a list of geodetic benchmark locations for Ontario? (If a list even exists that is...)
It's also available at Geobase Canada (Geodetic Network): http://www.geobase.ca/geobase/en/data/geod/index.html
I believe you can download it from Natural Resources Canada, but you will need to apply for a login (free): http://www.geod.nrcan.gc.ca/online_data_e.php
Apparently GeoBase provides them as grouped shapefiles based on your selected location, but I'm not entirely sure if it is complete.
edit: I meant GeoBase not GeoConnections.
