To reply to myself, I just thought I'd mention that it's trivially easy
to add/remove layers. Reference the following page, about 3/4 down,
under the heading "Data layers available", there are instructions on
which layers are available, and in what order to specify them.

http://geogratis.cgdi.gc.ca/geogratis/en/service/toporama.html

Basically, you'd take the URL I showed in my last email, and add/remove
the names from the page.  When you're putting the names in the URL, use
all lower case letters, and use a _ instead of spaces, and you should be
good to go.

An example might be 

http://wms.ess-ws.nrcan.gc.ca/wms/toporama_en?REQUEST=GetMap&SERVICE=wms&VERSION=1.1.1&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&FORMAT=image/png&LAYERS=limits,built_up_areas,constructions,road_network,railway,populated_places,structures,feature_names

for a map of the places us people have decided to live :)

I think I've been using source=toporama in cases where I've traced
things, but mostly I've been using it to smooth out coastlines, and make
sure that some of the beach trails I've been mapping lately don't veer
off into the ocean :)

peace,
	Austin.
