There is no error or anything, just a blank display as though the contents simply don't fall within the extents of the map (I have triple checked this possibility).

Joanne,

The critical item for the layer in question is whether the
ntv1_can.dat file (or better yet ntv2_0.gsb) exists 
in the directory /usr/local/proj-4.4.5/nad.  This is not
installed by default with PROJ.4 - you need to separately
download the datum shift files and unpack them before 
configuring and installing PROJ.4.   

Assuming you have the ntv1_can.dat file on your development
server, you can just copy that one file over to your corporate
server if you want.  

Best regards,
