Saskatchewan Court: New Evidence Can Reopen Benefits Claims

Sask. court rules new evidence can reopen income replacement benefits claims after a missed appeal deadline Missing a deadline to appeal a benefits denial is not always the end of the road. That is the takeaway from ruling by the Court of Appeal for Saskatchewan in SGI v. Wuttunee , 2026 SKCA 100. Here, the court held that a claimant can still recover income replacement benefits for a period covered by an unappealed decision, if new evidence surfaces and Saskatchewan Government Insurance (SGI) issues a subsequent decision letter that re-engages those same issues. The decision resolves two cross-appeals spanning more than two decades of benefit disputes between Nathan Wuttunee and SGI under The Automobile Accident Insurance Act (AAIA). At the heart of the ruling is s. 188 of the AAIA, which states that SGI decisions are “final and conclusive.” SGI argued this meant any unappealed decision letter was permanently off the table. The court disagreed . It held that s. 188 does not create res judicata or issue estoppel. When new information arises, ss. 170 and 171 of the AAIA allow a claimant to bring a fresh request for benefits. Once SGI issues a new decision letter in response, a fresh right of appeal opens, even if it covers a time period addressed in an earlier, unappealed letter. The court applied this principle directly to Wuttunee’s situation: The court allowed Wuttunee’s appeal and awarded him income replacement benefits for May 11, 2011, to August 7, 2014, which is the period the lower court had found to be statute-barred. The ruling reaffirmed two principles established in Saskatchewan Government Insurance v. Schira , 2020 SKCA 88 , and Seib v. Saskatchewan Government Insurance , 2025 SKCA 108 : SGI is a first-party insurer, not an adjudicative tribunal, and appeals under s. 192 of the AAIA are de novo proceedings. This means parties are not confined to the evidence SGI had when it made its original decision. New expert reports, updated medical assessments, and other evidence gathered after the fact are all fair game at the hearing stage. The court also addressed SGI’s argument that Wuttunee’s 2014 seizure recurrence triggered the relapse provisions under s. 141 of the AAIA , which treats a relapse occurring two or more years after the last benefit period as a second accident. The court rejected this. Wuttunee never regained the ability to return to construction work after his 2008 relapse. SGI also never identified suitable alternative employment under ss. 132 and 134 of the AAIA. On that basis, the court found the 2014 event was a continuation of an ongoing inability to hold employment under s. 113(4), not a new relapse. Sections 140 and 141 therefore did not apply. SGI’s appeal was dismissed in full. Bookmark Canadian Lawyer’s Personal Injury page for more news, articles, and updates for Canadian legal professionals.
