O-Train Line 1 partially resumed on March 14, 2026, after ice storm damage halted service east of uOttawa Station.

O-Train Line 1 service in Ottawa was partially restored on March 14, 2026, after being disrupted since a March 11 ice storm caused damage to overhead power lines, leading to electrical arcing and service cuts east of uOttawa Station. Service was extended to St-Laurent Station following ice removal and system re-energization. Out-of-service trains operated between uOttawa and St-Laurent, while buses served the St-Laurent to Blair segment. Final repairs at Blair Station were ongoing, with full service between Tunney’s Pasture and Blair expected to resume Sunday. Lines 2 and 4 continued operating normally.
