Thank you again Ottawa_Chap
You seem quite knowledgeable regarding all of this. I've downloaded the template, made the changes and will head off to the post office soon to send by registered mail.
I don't have cancelled cheques unfortunately, as they are asking for 1 month's rent since I gave 46 days written notice that I was leaving. They also had you pay directly into their account from your bank. I have been told that if it does go to SCC, they have to prove that they tried to rent the unit the month after I left. I know they didn.t because I went to pick up mail from a neighbour and she commented on how they were fixing all the things they didn't fix when I lived there. I'd also love to get them on the fact that the lights were burned out quite often in the undercover parking. My car was stolen a few months before I left, and that put me in financial difficulty as I needed a car in order to get to work, and purchased a 10 year old vehicle 3 months later.
Anyway, that's my problem. But I can't thank you enough - hopefully this is the end of everything!
Have a great week! P.S. Love your signature!
