Hi there, Ron.
Yes, you can keep access to your QBO account after canceling your subscription.
When you cancel a QuickBooks Online account, you'll be able to view your data in a read-only format for one year. After that year, you'll need to resubscribe to regain access to your data.

If you need to resubscribe, feel free to check out this article: Resubscribe or reactivate.
Let me know if you have further questions about QuickBooks Online. We're always ready to help.
