I used to work for TELUS, but not on the carrier side, so I don't have access to that sort of information. I'm based in Ontario, so I know more about those resources with Bell Canada. Check out http://www.hackcanada.com/. They claim TELUS is their local carrier (http://www.hackcanada.com/telco/index.html), and since there's no love there they're willing to give up all kinds of interesting information. Let me know how it turns out - I'll help however I can.
