If you willing to add the road names then I can't think of reasons why you 
can't proceed with importing communities in Ontario.  We probably need a 
discussion before bulk importing of unamed roads.

If you post the errors your getting with roadmatcher and I can tell you if 
they are  familiar.  I loaded both the NRN and OSM (with osm2pgsql) into 
PostGIS then used ogr2ogr to create .shp files for the area I'm interested 
in with most of the attributes stripped out.  One thing 
to keep in mind is that sometimes OSM road names are longer than 80 
characters which causes problems in load shapefiles, I truncate them during 
my extraction process.

Also, the version of geobase2osm.py in svn doesn't have the changes to 
exclude standalone roads.  I've sent it to Jason to commit, I'll send you a 
copy off-list as well.  It handles the tagging of the ways.
