He previously competed with Estelle Elizabeth, winning two junior national titles and representing France at the inaugural Winter Youth Olympics.

Elizabeth/Le Gac finished fifteenth at the 2013 World Junior Championships in Milan after ranking thirteenth in the short and eighteenth in the free dance.

[3] Le Gac relocated with Haguenauer to Montreal, Quebec, in July 2014, and was paired with Canadian ice dancer Marie-Jade Lauriault the same month.

They won two medals on the Junior Grand Prix (JGP) series — silver in Linz, Austria and gold in Logroño, Spain.

In March, they represented France at the 2016 World Junior Championships in Debrecen, Hungary, and won a small bronze medal after placing third in the short dance.

They were then invited to make their senior Grand Prix debut, finishing sixth at both the 2016 NHK Trophy and the 2017 Internationaux de France.

[6] Sixth at the Autumn Classic to start the season, Lauriault/Le Gac were eighth at both the 2017 NHK Trophy and the 2017 Rostelecom Cup on the Grand Prix.

[6] After a bronze medal win at the 2019 CS Autumn Classic International, Lauriault/Le Gac struggled in the early going, coming eighth at both the 2019 Skate America and the 2019 Internationaux de France.

[6] They were assigned to compete at the 2020 World Championships, to be held in Montreal near their training centre, but the event was cancelled due to the onset of the COVID-19 pandemic.

[8] After not competing at all during the COVID-plagued 2020–21 season, Lauriault and Le Gac announced on June 6, 2021, that they would henceforth be representing her birth country of Canada.

"[10] After competing domestically in the fall, Lauriault/Le Gac qualified for the 2022 Canadian Championships, held without an audience in Ottawa due to the spread of the Omicron variant.

[17] Despite their national bronze medal, Lauriault/Le Gac were not initially assigned to any ISU championships for the second half of the season, as Gilles/Poirier were expected to return in time.

[19] For their free dance for the new season, Lauriault and Le Gac chose to use the soundtrack of Tim Burton's film The Corpse Bride, which she would later say they had had contemplated since their junior days, but earlier felt would be too "childish".

[24] With Lajoie/Lagha still unable to compete, Lauriault/Le Gac replaced them at the 2024 Four Continents Championships in Shanghai, where they were seventh in the rhythm dance after receiving a two-point deduction for an illegal move in their rotational lift.

They set a new personal best score in the free dance, coming third in that segment and winning a bronze small medal, and rising to fifth overall.

Going on to compete on the 2024–25 Grand Prix circuit, the duo finished seventh at the 2024 Skate America, dealing with errors in the free dance.
