Hi yanni@kdbuilding,

It's a pleasure to see you reaching out to us here.  I can see how concerning this is, when you need to keep your QuickBooks Online data for 7-years and remain in good standing with the CRA.  I'd be happy to provide some insight here!

Once you cancel your QuickBooks Online account, you'll have access to your data for one year from the date of cancellation.  To extend the time frame, you can simply log into your account any time before the one year period ends and reactivate your account.  The subscription fee is prorated, so this provides you with a full month of usage to review your data and make any changes as you feel necessary.  At the end of the month, just cancel the account.  This will provide you with another full year of read-only access.  Ideally, I suggest exporting your data and saving it to a file for easy access.  

Feel free to reach back out if you have additional questions or concerns.  We're here for you!
