First Chapter of Blueprint for Victory, Canadian Military Vehicle Series Vol 3.
Believe also they are covered in The observer's army vehicles directory to 1940
research and editing by Bart H. Vanderveen.
Believe I have also seen photos at the Canadian War Museum.
Is there something in particular you are looking for?
Also take a look at
http://www.journal.forces.gc.ca/vo1/...93-102-eng.pdf pictures are not great resolution but the bibliography at the end looks fairly complete.
