After taking a two-season break from the sport, they returned to competition in the fall of 2016 and became the 2017 World champions, having an unprecedented undefeated season.

[11] Having skated together for over twenty years, Virtue and Moir are the longest-standing ice dance team in Canadian history.

[2] In 2018, Time magazine noted that "they've become especially beloved by new and returning spectators alike for their passionate performances and undeniable chemistry, on and off the ice".

She began skating at age six, having felt motivated to do so after a school field trip was set to take place at an ice arena.

[18] Two years into her partnership with Moir, a nine-year-old Virtue passed up the opportunity to enter the National Ballet School to devote herself to skating.

"[27] After several years of dating, Virtue's engagement to Toronto Maple Leafs defenceman Morgan Rielly was reported in early 2023.

Over the summer of 2004, Virtue and Moir moved to Canton, Michigan, and began working with Russian coaches Igor Shpilband and Marina Zueva at the Arctic Edge Ice Arena.

In spite of still being on the junior circuit, their placement led to them being named to the team to the 2006 Four Continents, their first international senior competition, where they won the bronze medal.

[34][37] As of this season, having gone undefeated in the international junior circuit, Virtue and Moir are the most decorated junior-level Canadian ice dancers.

They were the silver medallists at the 2008 World Championships in Sweden, winning the free dance segment with their program to The Umbrellas of Cherbourg soundtrack.

At the 2009 Four Continents Championships, Virtue and Moir finished second behind their friends and training partners, Americans Meryl Davis and Charlie White.

Virtue/Moir started off the 2009–10 Olympic season at the 2009 Trophée Éric Bompard, finishing first by a margin of 16.07 points ahead of the silver medallists, Nathalie Péchalat and Fabian Bourzat.

In January 2010, Virtue and Moir won their third national title at the 2010 Canadian Championships, placing first in all three segments of the competition and earning 221.95 points overall, which was 37.25 ahead of silver medallists Vanessa Crone and Paul Poirier.

[44][45] For the 2010–11 Grand Prix season, Virtue and Moir were assigned to the 2010 Skate Canada International and to the 2010 Trophée Éric Bompard.

Virtue underwent surgery in October 2010 to reduce the lingering pain in her shins and calves that is a result of chronic exertional compartment syndrome, leading to their withdrawal from the Grand Prix circuit.

[49] Virtue/Moir were assigned to two Grand Prix events, 2011 Skate Canada and 2011 Trophée Éric Bompard, having declined a newly introduced option to compete in a third.

Virtue and Moir then competed at the 2012 World Championships and won the gold medal, finishing first in both segments ahead of silver medallists Davis and White.

At Skate Canada, they won the short dance with a score of 65.09, only 0.01 points ahead of Anna Cappellini and Luca Lanotte of Italy.

During their free dance, Virtue felt cramping in her legs and paused the performance; they resumed after about three minutes and finished second to Davis and White.

They were assigned to two Grand Prix events for the season, the 2013 Skate Canada International and the 2013 Trophée Éric Bompard, and won both competitions.

On February 20, 2016, following a two-year break from the sport, Virtue and Moir announced on CBC's Road to the Olympic Games that they planned to return to competition for the 2016–17 figure skating season and that they had moved to Montreal, with former competitors Marie-France Dubreuil and Patrice Lauzon as their new coaches.

Two weeks later, they topped those scores, receiving 80.5 in the short dance and 197.22 total at the Grand Prix Final in Marseille, France, which they won for the first time in their career.

They received a score of 82.43 and had a huge 5.5-point lead over reigning champions and training partners Gabriella Papadakis and Guillaume Cizeron.

For the 2017–2018 season, Virtue and Moir chose The Rolling Stones, the Eagles, and Santana for their short dance, and skated to the Moulin Rouge!

At the 2017 Grand Prix Final, Virtue and Moir lost for the first time since their return to competition, finishing second to training mates and main rivals Gabriella Papadakis and Guillaume Cizeron of France, who had a half-point lead after the short dance.

[86][87] After the competition, they changed a "risque" lift in their Moulin Rouge routine that had involved Virtue's legs wrapped around Moir's head.

[93] They then placed second in the free dance, but their score was enough to win them their second individual Olympic title on February 20, 2018, exactly two years after announcing their competitive comeback.

[3] In October 2010, Virtue, Moir, and co-writer Steve Milton published a book about their career called Tessa and Scott: Our Journey from Childhood Dream to Gold.

Throughout Virtue and Moir's competitive skating career they have been sponsored by many Canadian companies;[102] these include Visa, Air Canada, Acura West, Lindt, and General Mills.

Virtue has been individually sponsored[102] by companies including Adidas, Nivea (as its first Canadian brand advertiser), Colgate, and MAC Cosmetics.
