This is accurate. I was briefly involved with sqtroff, because it was brought to York U
by one of the founders (david slocombe) to publish York's newsletter.
see this for coach house press history. possibly the first (outside bell) unix-based publisher.

Interesting. That sounds like a different commercial strain, "SoftQuad
was started in order to improve automated typesetting at Toronto's
Coach House Press, and for many years developed an enhanced commercial
version of the text formatting program troff, developed under license
from AT&T, called sqtroff. It was sold with a suite of associated
programs, corresponding to AT&T's Documenter's Workbench, under the
name SoftQuad Publishing Software (SQPS)."
