Subrogation exists to make policyholders whole while preventing at-fault parties from escaping financial responsibility for the harm they cause. Throughout this course, we have examined how insurers step into the shoes of their insureds to pursue recovery against negligent third parties, how cooperation clauses function, and how the subrogation process unfolds across Canadian jurisdictions. This final lesson addresses a critical dimension that directly affects policyholders: what happens when insurance does not cover every loss, and how subrogated recoveries interact with uninsured portions of a claim. Understanding this interplay is essential for insurance professionals, adjusters, brokers, and risk managers who advise clients navigating the aftermath of insured events where their total loss exceeds what their policy pays.
The concept of uninsured loss in the subrogation context refers to any portion of damages that the policyholder bears personally because their insurance coverage does not extend to it. This can arise from deductibles, which represent the most common form of uninsured loss, but it extends far beyond that single mechanism. Depreciation holdbacks on property claims, coverage sublimits that cap recovery for specific categories of property, waiting periods on business interruption coverage, policy exclusions that carve out certain types of damage, and outright coverage gaps where the policyholder lacks insurance for a particular risk all create situations where the insured suffers financial harm that their own policy does not indemnify. When a third party caused the loss and the insurer pursues subrogation, the question naturally arises: who has priority to recover from the at-fault party when the available funds do not fully compensate both the insurer and the insured for their respective portions?
