Difficulty uploading documents

If you experience difficulty uploading documents to RIO, the Child Support Recalculation Program is aware of this issue and has reported it to the Government of Alberta technical team responsible for RIO. The technical team continues to search for a solution to resolve the issue.

System updates to the computer database that the RIO system is part of occur after 8 pm each weeknight. You may have difficulties uploading documents after 8 pm. We encourage you to try to upload earlier in the day or on weekends.


Once you are registered with the program, RIO allows you to both see and provide key information in a secure way. RIO helps you meet your legal obligations to:

  • update your contact details
  • provide income information each year

Regular system updates

System maintenance for RIO occurs every weeknight and Sunday morning. If you are unable to access the system, try again later. We apologize for any inconvenience.
