As I recall, Dodge & Bell came from Waterloo, but I don't think QNX
is very similar to Thoth (aside from a reliance on message-passing).
Thoth did find a commercial incarnation In Spectrix, which died out a
couple of years ago (the company still exists, but not the o/s). Other
Thoth-like derivatives are Harmony, developped at the National Research
Council (of Canada), which has now gone commercial, and (I think)
Waterloo Microsystems' PORT o/s. And of course Cheriton carried the
concepts on to the V system at Stanford. I think you're right about
the original spelling of QNX and why it was changed.

BTW, the QNX book is now available from Basis Computer Systems in Toronto,
Canada: (416) 495-1491 (i.e., direct from the publisher only).
