No direct instructions, but some hints & places to look:
r.in.gdal covers most kinds of formats you can think of.
See "supported formats" at http://www.remotesensing.org/gdal
some quick googling:
This PDF file provides the details of the CDED dem format:
This page states the format is created by Australian National
University Digital Elevation Model software, and is pretty much just
a USGS DEM.
Finally, (uncleaned) SRTM-3" data is available for most of North America,
you might try that for a high-res DEM. (southern Canada at high(est)
resolution; nothing for northern Canada...)
If you still have no joy, you might have to hire someone to include
support for CDED in GDAL or elsewhere... I think it would be pretty
straight forward & quick to do. The folks at remotesensing.org or
http://www.tekmap.ns.ca might be able to help you out (among others).
