Sycerika McMahon completed the Canadian National Championships last night achieving Commonwealth Games nomination times in five events.
The Portaferry teenager swam nomination times in the 50m, 100m and 200m breaststroke, 400m freestyle and 200m individual medley.
The qualification period is due to end after the Irish National Championships in Dublin at the end of the month.
McMahon represented Northern Ireland at the 2010 Games in Delhi as a 15-year-old.
The 2012 Olympian's times are also inside the qualification standard set down by Swim Ireland for the European Championships in Berlin in August.
The Commonwealth Games take place in Glasgow in July and August.
