If it were me I would not re-flash anything. The connection problem would not likely be from a carrier unlock. Also it is not likely it would be from rooting or installing the CWM boot loader.
You have a known system now, you know when it worked, and you know the few modifications you have done. Even if you have called Chatr tech support before, it might help to call again and tell them it will not log on to their system. DO NOT tell them you have rooted the phone, DO NOT tell them you installed a boot loader. If you do that, they will probably say that is the problem, END of support. Just say it was unlocked by a dealer and now takes their SIM but it won't work.
They should walk you through each step of the configuration, they want your money every month, you want their service. Good place to start. Give them your IMEI, make sure it's good and not 'blocked'. it's in the settings/about device/status or dial *#06#. I'm assuming you already have confirmed your phone is comparable with chatr, I think you mentioned it was from TELUS, but with BELL, ROGERS or whatever, unlocking does not guarantee the Modem is the same as the new network you are trying to use.. There are several other reasons, but SIM, IMEI and improper configuration are the most likely problems if compatible.
There is a chance it is something simple that has been missed. You have shown patience, that is a big plus with modding phones. Going step by step and being willing to start over is something many here have done, and many times. Small problems are sometime the easiest to miss. So Call Chatr tech support, if they have an outlet near you maybe you can get a replacement SIM from them, (I would check that first) as I mentioned before.
One other thing to try, see if you can get a new Pre-Pay/month to month SIM from TELUS or the original carrier the phone was branded for. It should work and if not, they know their configuration. I'm out of suggestions, hopefully someone from Canada can be of more help. Don't give up. There are always answers.
