Late Nerve Test Wins Chronic Pain Claim Against Pembridge in Ontario MIG Dispute
An Ontario auto insurance dispute has been decided in favour of a chronic pain claimant, with a late-submitted nerve test outweighing Pembridge Insurance's medical examination and removing the claim from the Minor Injury Guideline (MIG) cap.
What happened
A chronic pain claimant under Ontario's auto insurance system successfully challenged Pembridge Insurance's attempt to keep the claim within the Minor Injury Guideline (MIG). A nerve conduction study, even though filed later than standard timelines, was treated as decisive evidence and overcame the findings from Pembridge's independent medical examination. The decision effectively moved the claimant out of the MIG category.
What it means for consumers
Ontario policyholders dealing with chronic pain after a collision now have a clearer example of how objective diagnostic testing can outweigh an insurer-arranged medical assessment. Insurers cannot rely solely on their own scheduled exams to lock a claim inside the MIG when neurological testing points to more serious impairment. Claimants should preserve and pursue nerve conduction or EMG evidence even if it surfaces after typical deadlines.
What it means for premiums
No direct premium change has been announced.
Coverage considerations
Being designated outside the MIG typically unlocks higher medical and rehabilitation funding limits, as well as more generous income replacement benefits than the capped MIG envelope. Claimants with documented nerve involvement or persistent pain may see broader access to treatment funding, longer-tail care plans, and accumulated benefit availability. Conversely, this kind of decision can pressure insurers to scrutinize MIG designations more carefully, which may influence how adjusters handle borderline chronic pain files going forward.
