It can, but MapServer only offers the projections that a layer is configured to support. To see these, just issue a GetCapabilities request. For the server from your snippet below, this would be http://www2.dmsolutions.ca/cgi-bin/mswms_gmap?request=GetCapabilities&service=WMS&version=1.1.1 As you can see, most layers in there are only provided in EPSG:42304. > It's just a reprojection, right?
