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's2014 Commonwealth Games team, where he placed fourth in the 100m Freestyle.[2]
In September 2017, he was named to Canada's team for the 2018 Commonwealth Games.[8][9] Kisil made the finals of both the 50 m and 100 m freestyle, finishing fifth and seventh. At the 2018 Pan Pacific Championships in Tokyo, Kisil captured bronze in the 50 m freestyle, his first major individual international medal. He said afterward "I've wanted to get on the podium individually for a long time. To finally do it here means the world.".[10] Following this, he departed longtime coach Tom Johnson to train in Toronto with Ben Titley, after being disappointed with the times he had been recording in the 100 m.[11]
2019 saw the launch of the International Swimming League, a professional competition circuit for swimmers. Kisil signed with the London Roar in the inaugural season. London Roar was one of the four team to reach the ISL's season finale in Las Vegas, where they finished in second place.[12] In spring 2020, Kisil signed with the Toronto Titans, the first Canada-based team in the ISL.[13] Competing at the 2019 World Aquatics Championships in Gwangju, he came seventeenth in the heats of the 100 m, just missing the semi-finals.[11]
The onset of the COVID-19 pandemic resulted in the 2020 Summer Olympics being delayed by a year. In June 2021, Kisil was named to Canada's 2020 Olympic team.[14][15][16] He was part of Canada's team in the 4 × 100 m freestyle relay, who unexpectedly finished in fourth place despite not even being initially favoured to make the event final.[17]
