You've never made a payment, so when was the first payment due? That would be your DOFD, which is what the 7 year reporting time goes from.

Is this site the only place you've gotten your reports?

If so, I suggest that you pull your free annual reports, as they come directly from the CRA and have much more information that other reports gotten elsewhere.

You need to know the actual DOFD, which is shown on your EQ report gotten directly from EQ and on your TU and EX reports it will show a removal date.

The CA is reporting on your reports, correct? Not the OC.
