The claimant sought entitlement to income replacement benefits. The insurer asserted a limitations defence. Adjudicator Sewrattan noted that the LAT assumed jurisdiction of accident benefits disputes on April 1, 2016. The parties agreed the 90-day grace period beyond a report of mediator is not applicable to LAT disputes. Adjudicator Sewrattan noted the claimant had ample time when counsel was retained to dispute IRBs. Accordingly, the limitations provisions of section 56 governed and the claimant was time-barred from bringing an IRB claim.
