Before you do anything google credit-collections.ca for some very good information about collections in Canada. They show you how the worst in Canada operate and how they are trying to rip you off.

Always get a bi-monthly print out of your Equifax File so you can be up today with your payments you are making.  This will get the callers off your backs as you have proof in front of you to say you own no monies to anybody.  I have had to change my number twice because of the harassing calls but not any more.
