" The difficulty is that I'm nowhere near a university library, but I'll have to overcome that somehow.
These are widely accessible electronically these days. And I am one who has a password. I'll see what I can find.
And there are public access historic/heritage resource services such as;
Early Canadiana Online (subscription fee);
http://www.canadiana.org/en/
Exploration, the Fur Trade and the Hudson's Bay Company;
http://www.canadiana.org/hbc/intro_e.html
Includes microfiche searches, now computerized! for those who remember sitting long hours in libraries feeding cellulose into the reader.
Library & Archives of Canada;
http://www.collectionscanada.gc.ca/caninfo/ep097.htm
I did a quick search of the terms "canoe" and "dugout". No references found for "dugout".
Interestingly, other searches for dugout bring up baseball related stuff. Note; there is an internet information service in Canada called "Canoe", so that comes up a lot.
I recall an earlier thread on this Forum of someone researching dugout building techniques to reproduce one for use in a film production. I did an archival search and didn't come up with anything.
The Smithsonian has searchable archives in American History and Culture and American Indian here;

Searching ABE and AddAll book searches, I didn't find any available copies of either
"Canoe and Kayak Books" by Jerry Cassell, 1997 or "Log Boats of North America" by Timothy Kent.
Note Timothy Kent also authored, "Birchbark Canoes of the Fur Trade; Vols I & II".
Will look for both via a university library.
