Canadian CS University Positions?
The Canadian CS community is seriously under-server and under-organized.  The ACM (in the US) completely overshadows us, and since it (nominally anyways) tries to be international, that leaves little room for Canadians to get organized.  So typical community-driven issues, like aggregating jobs, does not happen.  The community is (now) large enough to be able to sustain such an organization (I know, I belong to the CMS, the Canadian Mathematical Society, and it manages just fine, and the sizes involved are in the same ballpark).

I realize that this answer is a bit of a non-answer.  But the (unfortunate!) answer to your question is 'no'.  So rather than just saying that, I figured I would elaborate.

Ok, so apparently my Google-fu was not good enough.  I just stumbled upon the CACS/AIC, which is the Canadian Association of Computer Science.  But the web site is astonishingly bare bones, with no real sign of the purpose, etc.  So still a 'no', but not quite exactly as I had said.  And CIPS is different, as it really focused on the IT side of things, not so much on the CS.
