Here's a URL that seems to work:
http://wms.ess-ws.nrcan.gc.ca/wms/toporama_en?LAYERS=limits,vegetation,builtup_areas,designated_areas,hydrography,hypsography,water_saturated_soils,landforms,constructions,water_features,road_network,railway,populated_places,structures,power_network,feature_names&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application/vnd.ogc.se_inimage&FORMAT=image/png&
Here's a URL that doesn't seem to work:
http://wms.ess-ws.nrcan.gc.ca/wms/toporama_en?LAYERS=limits%2Cvegetation%2Cdesignated_areas%2Chydrography%2Chypsography%2Cfeature_names&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&FORMAT=image%2Fpng&
Here's another that doesn't seem to work:
http://wms.ess-ws.nrcan.gc.ca/wms/toporama_en?REQUEST=GetMap&SERVICE=wms&VERSION=1.1.1&SRS=epsg:4269&BBOX=-72,45.35,-71.85,45.5&WIDTH=800&HEIGHT=600&FORMAT=image/png&LAYERS=vegetation,builtup_areas,hydrography
These were all copied from pages that purported to be good URLs...

So I had the first URL working last night. Today at work it didn't
work. Tonight back home, it works again. Perhaps that has something to
do with firewalls of other issues at work that are out of my control.
Is there some way to tell if the link isn't working properly, or if it
is failing? These are two separate issues, and fighting with trying to
get links figured out when the issue is a firewall in the way or such
can be an exercise in futility.
