Our library has a catalogue record for the microfiche version of this publication, a form I would rather not have to use. I have found the HTML version archived by Statistics Canada: <http://www.statcan.gc.ca/pub/11-533-x/finding-trouver/4155245-eng.htm>. Is this a permanent link? I don't see anything that looks like DOI?
It is quite uncommon to find truly "permanent" links on Statistics Canada, particularly since this one isn't even offered as a PDF file. We do not have DOIs at Statistics Canada. Instead the client should be pointed to our online catalogue which has the most current information about this product and where the links are stable:<http://www5.statcan.gc.ca/olc-cel/olc. action?ObjId=11-533-X&ObjType=2&lang=en &limit=0>
