Hang on there. You misunderstood me. While provincial consumer reporting legislation allows debts to be reported for 7 years from the date of last payment or collection, the credit bureaus have an internal policy of 6 years from the date of "FIRST DELINQUENCY." with respect to their "trade" sections.
You can see from the top of page 8 of the same link I just sent the last guy
http://www.fcac-acfc.gc.ca/eng/publications/CreditReportScore/PDF/CreditReportScore_e.pdf
that the credit bureaus' policy is to report from the date that account payments FIRST went into default - NOT when you last paid a stinking collector. So if you make a payment on a card after it's been delinquent for 5 years, that doesn't mean that it is supposed to stay on your report for another 6.
However, what happens in practice, is that the collection agency really couldn't care less and punches in the last payment date or date of last activity as being when they received a collection from you. That's the date which is often fed into the credit bureau's database and so that's what has to be disputed. Again, that's why I tell people to keep their old billing statements.
