The Ontario SABS Landscape

If you're working in Ontario auto insurance, you're working under the Statutory Accident Benefits Schedule (SABS) — Ontario Regulation 34/10 under the Insurance Act.

SABS governs accident benefits for people injured in motor vehicle accidents in Ontario. It specifies what benefits are available, who qualifies, and what medical documentation is required.

This post covers the medical records requirements under SABS — what you need to know to navigate Ontario auto insurance claims.

Medical Documentation Requirements Under SABS

1. Disability Certificate (OCF-3)

When it's required:

  • To apply for Income Replacement Benefits

  • Whether the claimant is unable to provide care (for Caregiver Benefits)
  • Whether the claimant is unable to perform housekeeping tasks (for Housekeeping Benefits)

Key considerations:

  • The certifying professional must have examined the claimant
  • The certification must be based on objective clinical findings
  • The certification must be provided within the time limits specified in SABS

2. Treatment and Assessment Plan (OCF-18)

What it is: A form submitted to the insurance company requesting approval for medical and rehabilitation treatment or assessment.

When it's required:

  • Before providing treatment or assessment for non-minor injuries
  • For treatment plans exceeding $3,500 (minor injury guideline)
