The Canadian pairs team of Deanna Stellato-Dudek and Maxime Deschamps will join fellow world champions Ilia Malinin and Kaori Sakamoto to headline a strong field at Skate Canada International this week.

The second Grand Prix stop of the year goes Friday through Sunday at Scotiabank Centre as the pre-Olympic figure skating season kicks into high gear for Canada's top medal hopes.

Here's a look at five things to know heading into the event:

Back again

After skating to silver at the world championships in Montreal, ice dancers Piper Gilles and Paul Poirier are back for another season.

The decorated duo has made a habit of opening its season at Skate Canada — and winning. The two 32-year-olds have topped the podium in four straight years of the competition (the 2020 event was cancelled). This weekend, they'll aim for a fifth victory to kick-start a season they hope culminates in their first world championship title in Boston next March.

Gilles and Poirier's biggest rivals, two-time defending world champions Madison Chock and Evan Bates of the United States, will not be competing at Skate Canada. Instead, their stiffest competition may come from fellow Canadians Marjorie Lajoie and Zachary Lagha, who won two Grand Prix silver medals and placed fifth at worlds last season.

Lajoie and Lagha withdrew from the Budapest Trophy Challenger event two weeks ago due to an undisclosed injury but are expected to compete in Halifax.

Skate America is the first stop of the Grand Prix season, and Asher Hill and Brenda Irving are here to catch you up on what you missed in the off-season, and prep you for who to look for on the ice this season. Skate America is streaming live on CBC Gem beginning October 18th at 7 PM ET.

Defending gold

Also looking to repeat at Skate Canada International are Stellato-Dudek and Deschamps.

Stellato-Dudek is still seeking Canadian citizenship to compete at the 2026 Olympics in Milano-Cortina. The Chicago native couldn't share specifics about a "new development" with her nationality last week but said "things are moving in the right direction."

The world champions opened their season by claiming silver at the Nebelhorn Trophy Challenger event in September. In Halifax, their biggest challengers will be Annika Hocke and Robert Kunkel of Germany, who rank sixth in the world.

Best of the best

Men's champion Malinin of the U.S. — the self-proclaimed "Quad God" — and three-time reigning women's champion Sakamoto of Japan are also gracing the ice surface this weekend.

Malinin is back in Canada after scoring a world-record 227.79 points with a jaw-dropping six-quad performance during his free program in Montreal. The 19-year-old phenom won Skate America last Sunday and is the early favourite to claim gold at the 2026 Olympics.

Malinin skates to 3rd consecutive Skate America title

Ilia Malinin of Vienna, Virginia scored 290.12 which easily was enough to win another Skate America title Sunday in Allen, Texas

And this year, he's doing backflips. While skaters used to be penalized for the move, backflips and other somersault-type jumps are no longer banned by the International Skating Union. Malinin landed one en route to victory at Skate America.

Sakamoto is aiming for a fourth straight world title this season. Carol Heiss of the U.S. was the last woman to achieve the feat, winning five consecutive titles from 1956-1960.

Singles hopes?

Canadians aren't likely to challenge Malinin or Sakamoto. Canada hasn't won a singles medal at the world championships since Kaetlyn Osmond captured women's gold in 2018, and the last men's medallist was Patrick Chan in 2013.

Madeline Schizas, who finished 18th at worlds, and 17-year-old Canadian champion Kaiya Ruiter are Canada's top women's entries in Halifax. For the men, 2022 Olympian Roman Sadovsky is set to take the ice along with youngsters Aleksa Rakic and Stephen Gogolev.

About the Grand Prix

The Grand Prix, the top series in figure skating, consists of six events and a final. This year's circuit kicked off at Skate America last week and includes competitions in Halifax, France, Japan, Finland and China. The top six skaters in each discipline advance to the Grand Prix final in France in early December.

Skate Canada begins Friday night with the pairs and women's short programs. The rhythm dance and men's short take place Saturday afternoon, followed by the pairs and women's free programs in the evening. The competition wraps up Sunday afternoon with the men's free program and the free dance.
