Here are seven can’t miss races for this weekend’s meet in Toronto.

How fast can Katie Ledecky go? The greatest distance swimmer in history doesn’t short course meters often, so the world record of 3:53.92 by Australia’s Ariarne Titmus could be in jeopardy this coming weekend. Ledecky has a best time of 3:54.06 from late 2019, so it’s not as if she will go in and go 3:52 without breaking a sweat, but all eyes will be on the clock when she dives in.

Ledecky will also be racing with the two medalists from this summer’s World Championships - longtime teammate Leah Smith and rising Canadian star Summer McIntosh in her former home pool. McIntosh and Ledecky went toe to toe this summer in the 400 freestyle in long course and the Canadian 15-year-old seems to be getting faster any time she dives in the pool. If anyone can beat the almighty Ledecky, it could be McIntosh.

Women’s 400m IM

Summer McIntosh’s best event is probably the 400 IM, and if she is in the right shape, then who knows, maybe that 4:18.94 world record by Mireia Belmonte could be in danger of falling. McIntosh has quickly become a star in the sport of swimming and will be racing in front of a Toronto crowd that will be itching to see her as she prepares for a potentially big summer in 2023.

McIntosh’s biggest challenges could come from USA’s Hali Flickinger and Leah Smith, the former winning the Olympic bronze medal in this event at the 2020 Olympics in Tokyo.

Canada’s Joshua Liendo, now training in the United States at the University of Florida, will be returning to his former home of Toronto to give the Canadian crowd a show. Liendo broke out this summer with individual bronze in the 100m freestyle and 100m butterfly at this summer’s World Championships.

At age 20, Liendo will have his hands full with Australia’s world record holder Kyle Chalmers, who beat Liendo head-to-head this summer at the Commonwealth Games. Chalmers already won the 100m freestyle in Berlin and is looking to sweep the three stops in this event. But if anybody can take him down, it could be Liendo

Olympic champion Maggie MacNeil will be swimming in her signature event in front of the Toronto crowd, eager to see one of their favourite swimmers in action. MacNeil is the third fastest performer in history in the 100m butterfly in short course meters, but should still be pushed by Sweden’s Louise Hansson.

Hansson sits fifth all-time and already won the event in Berlin on stop #1 as she and MacNeil have done many battles over the years.

Perhaps one of the most intriguing races of the entire weekend in Toronto, the world record holder in short course and in long course will be going head to head as long course world record holder and reigning World champion Thomas Ceccon will be going head to head with short course meters world record holder Coleman Stewart along with Berlin winner Shaine Casas.

Casas got the upper hand over Ceccon in Berlin last week as they come up against a fresh Stewart, who has been nearly a full second faster than both Casas and Ceccon in his career, swimming a 48.33 last year.

World records may not be coming this weekend, but the race should still be exciting and fast, with Canada’s Javier Acevedo also expected to contend.

Ruta Meilutyte got closer than anyone to a world record in Berlin, swimming a 28.60 to just miss Alia Atkinson’s 28.56 record. Atkinson may not have much more time to have that world record as Meilutyte has reinvigorated her career and swimming faster than ever after being one of the top World Cup winners as a teenager a decade ago.

Meilutyte will have American Lilly King racing alongside her as King is third on the all-time list after Meilutyte. With the hype and intrigue building around a potential world record, it could elevate both Meilutyte and King to swim close to their best times or even faster.

Matthew Sates took round one over Kyle Chalmers in Berlin in the 200m freestyle as those two will once again lock horns in Toronto with Kieran Smith and Danas Rapsys expected to contend, as American Drew Kibler will add himself to the mix.

Sates won in come-from-behind fashion in Berlin with a 1:40.88 as Chalmers took out the first 100 faster than Paul Biedermann’s world record pace, which still stands at 1:39.37 from November 2009. Add in Kibler, who just missed the podium at this year’s World Championships and with his lack of short course meters experience, and he could be a big wild card to potentially play spoiler in the 200m free in his home state.
