What counts
- Equifax says this factor looks at how long your accounts have been open, including your oldest and most recent accounts.
- The FCAC gives an example: opening a new card to transfer a balance counts as a new account, may reduce the average age of your accounts and may lower your score.
Closing an old account
The FCAC says closing an older account means you lose older credit history and reduce your available credit. Keeping it open, even with a zero balance, helps you keep your history and can improve your utilization. It suggests keeping an account open if it has no annual fee, is easy to manage, and you can use it occasionally to keep it active. Check with your issuer about what happens to an unused card.
How long a closed account stays on your report
Sources disagree, so check before you rely on a number. Equifax Canada says an account paid as agreed stays up to 6 years from when the lender reports it closed. The FCAC page says closed accounts stay up to 10 years with Equifax, and up to 20 years with TransUnion.
Building history from scratch
Newcomers and young adults start with no history. One account used with care and kept open builds age over time. Time cannot be rushed, and each new application can add a hard inquiry and lower the average age, so avoid opening several accounts quickly.
Questions people ask
Does my oldest card matter more than the average?
Equifax says both your oldest and most recent accounts are included. We have not found a published weighting between them.
Will a new card hurt my score?
It may lower the average age and add an inquiry, according to the FCAC. The effect depends on the rest of your file, according to Equifax.
Should I keep a card I never use?
The FCAC suggests keeping it if there is no annual fee and you can use it occasionally.
