If you call Canadian Tire Credit in Welland, they'll likely refer you back to CRS, assuming the account is still with them, for settlement.
Canadian Tire or CRS can't touch your money in any other institution so you're safe. I thought the account might have been with one of the major banks.
If you want to settle for moral reasons (which are more important than financial), you could offer them 40% maybe. Perhaps a good bit less given it's age.
P.S. Needless to say, making a payment on this type of debt DOES NOT restart the Equifax or Trans Union 6 year reporting period nor revive any expired limitiation period.
P.S.(2) Also NEVER settle with a collection agency without FIRST obtaining a presigned agreement that the debt is in full and final settlement of the account. Come to an agreeement over the phone and then get them to send it to you in writing before sending money. Collection agents are notorious for this ruse, particularly the full patched members.
