Kisil's selection to the World Junior Championships in Dubai was his first major junior international competition. At this event he became the Canadian 15–17 age group national record holder in the 50 m Freestyle. Kisil was the youngest swimmer in Canadian history to win both the 50 m and 100 m freestyle national championships at the Canadian Swimming Trials in Victoria, British Columbia, on April 3, 2014. He was also the youngest Canadian to ever swim under 50 seconds in the 100m freestyle at the same event. As a result Kisil was named to Canada's 2014 Commonwealth Games team, where he placed fourth in the 100m Freestyle.
