I agree Monty. Depending on the province you are in there is also The Consumer's Protection Act and also I found through my research while writing my document a website Weblegallingo or something like this that has a section under the Canadian Criminal Code and creditor harrassment.
My last step with what happened to me is the OBSI. If nothing is resolved then I will seek legal counsel.
I have also been looking into Telephone Phreaking but so far found nothing concerning them taking over my telephone line for an hour and half but Give Up is not part of my vocabulary LOL.
