Family protection auto insurance is designed to protect an insured person when an at-fault motorist does not have enough liability insurance to satisfy the insured person’s compensatory bodily-injury claim. Depending on the provincial form, the protection can also address uninsured and unidentified motorists.
What family protection coverage is designed to do
There is no single national endorsement with one form number. Alberta uses AB-S.E.F. No. 44. Ontario uses OPCF 44R. Other provinces and public automobile systems structure underinsured-motorist protection differently.
Alberta uses SEF 44
Alberta’s current standard Family Protection Endorsement is AB-S.E.F. No. 44, effective March 1, 2023.
The endorsement defines an “inadequately insured motorist” broadly. It includes an identified owner or driver whose available liability insurance is below the Family Protection Coverage limit. It also includes the owner or driver of an uninsured automobile or an unidentified automobile.
The coverage is for compensatory damages arising from bodily injury or death. It is not vehicle-repair coverage.
If no separate Family Protection Coverage limit is shown on the policy or certificate, the standard Alberta form says the Section A liability limit becomes the Family Protection Coverage limit.
Ontario uses OPCF 44R, not SEF 44
Ontario’s comparable endorsement is OPCF 44R Family Protection Coverage.
Ontario’s regulator describes it as optional coverage that can protect the insured or an eligible family member up to the third-party liability limits where the insured is not at fault and the other motorist has less insurance, no insurance or cannot be identified, such as in a hit-and-run.
That is conceptually similar to Alberta’s SEF 44, but the forms are not interchangeable. Ontario’s current OPCF 44R was updated in July 2026, and Ontario’s broader automobile-insurance system is different from Alberta’s.
Underinsured, uninsured and unidentified are different factual problems
An underinsured motorist has liability insurance, but the available limit is insufficient relative to the applicable family-protection limit and the proven damages.
An uninsured motorist has no applicable and collectible liability insurance within the policy definition.
Limits, triggers and provincial differences
An unidentified motorist is one whose owner or driver cannot be identified. Those claims often carry special notice and proof conditions because the insurer cannot investigate or recover against a known tortfeasor in the ordinary way.
The endorsement wording determines how each category is treated.
Alberta’s current unidentified-vehicle rules are especially important
Under Alberta’s 2023 SEF 44, a claimant relying on an unidentified automobile must meet specific reporting requirements.
The accident must be reported within 24 hours to the specified public authority, and a sworn statement must be filed with the insurer within 30 days setting out the basis of the claim against the unidentified person.
Where both owner and driver cannot be determined, the claimant’s own evidence of the unidentified automobile’s involvement must also be corroborated by other material evidence. The endorsement defines that as independent witness evidence or physical evidence indicating the involvement of an unidentified automobile.
Notably, that wording does not state that physical contact itself is always required under the current SEF 44.
The limit is not simply an extra pile of insurance
Family protection coverage operates within a set of offsets, priority rules and maximum limits.
In Alberta, the endorsement takes account of the liability insurance and other amounts available from the inadequately insured motorist and other sources identified in the form. Uninsured-motorist coverage is also taken into account when the responsible driver is uninsured.
The practical result is that the Family Protection Coverage limit should not be understood as an amount automatically added on top of every other recovery.
What to compare on an actual policy
A useful review looks at:
- the liability limit on the automobile policy
- the family-protection endorsement and stated limit
- the people who meet the endorsement’s definition of insured person
- the definitions of inadequately insured, uninsured and unidentified motorist
- notice and proof requirements
- priority and offset provisions
- any insurer-specific endorsement that changes the standard form
Family protection is therefore best understood as a gap-filling bodily-injury protection, not as a generic national product. Alberta’s SEF 44 and Ontario’s OPCF 44R perform similar functions, but the form attached to the actual policy is the document that controls.
