Tardi first came onto the national curling scene skipping the host British Columbia team at the 2015 Canada Winter Games in Prince George, British Columbia where he would pick up a bronze medal. After losing in the British Columbia junior finals in both 2013 and 2014, Tardi and his rink of Daniel Wenzek, brother[5]Jordan and Nicholas Meister won the 2016 British Columbia men's junior championship. The team represented the province at the 2016 Canadian Junior Curling Championships, and went 7-3 after the round robin portion, making the playoffs in third place. The team would have to settle for a bronze medal after they lost to Manitoba's Matt Dunstone in the semi-final.
Tardi and his team of Middleton, Jordan Tardi, and Meister won a second provincial junior title in 2017. Representing British Columbia at the 2017 Canadian Junior Curling Championships, the team lost one round robin game en route to winning the national championship, defeating Ontario's Matthew Hall rink in the final. The team represented Canada at the 2017 World Junior Curling Championships, where they finished the round robin with a 6–3 record, but lost to Norway in a tiebreaker game. That year, Tardi also skipped British Columbia at the 2017 Canadian U18 Curling Championships, losing just one round robin game. However, he was not successful in the playoffs, losing in the semifinal, but rebounded in the bronze medal game, defeating Saskatchewan's Rylan Kleiter.
In 2018, Tardi, Middleton, Jordan and new lead Zac Curtis won a third provincial junior title. At the 2018 Canadian Junior Curling Championships, Tardi would defend his title. After losing three round robin games, he had to fight through a tiebreaker before winning two playoff games, including defeating Northern Ontario's Tanner Horgan rink in the final. The team represented Canada at the 2018 World Junior Curling Championships, where they were much more successful. The team lost two round robin games, and won both playoff games, including defeating Scotland in the final to claim the gold medal.
In 2019, Tardi and Middleton added a new front end of Matthew Hall, his opponent in the 2017 Junior finals and Alex Horvath and won a fourth provincial junior title. At the 2019 Canadian Junior Curling Championships, he led his province to his third-straight national championship, becoming the first skip to win three-straight junior championships.[6] Tardi lost just one game en route to the title, and defeated Manitoba's J.T. Ryan in the final. Tardi once again represented Canada at the 2019 World Junior Curling Championships. After posting a 7–2 round robin record, he won both playoff games, including defeating Switzerland's Marco Hösli rink in the final.
The 2019-20 curling season would have been Tardi's last year of junior eligibility, but he decided to make the jump to men's curling full-time, eschewing the junior ranks.[7]
Tardi qualified for his first men's provincial championship in 2016, but had to bow out due to his participation at that year's Youth Olympics. The rest of his team played short-handed, and went 2–3. Tardi played in the 2017 BC Men's Curling Championship, going 3-3. He didn't enter playdowns in 2018, but was back at it at the 2019 BC Men's Curling Championship. There, his team were eliminated after posting a 2–3 record. He finally made the playoffs at the 2020 BC Men's Curling Championship, where he lost in the final to Jim Cotter.
The Tardi rink disbanded in 2022,[9] with Tardi joining the Kevin Koe rink at third. The team represented Alberta at the 2023 Tim Hortons Brier, where they were eliminated in the page qualifying game.
