The Capitales compete in the Frontier League (FL) as a member of the North Division in the Atlantic Conference.

The club is known as one of the most popular independent baseball teams in North America, and have been extremely successful from 2009 to 2013 with five league championships in a row.

However, due to the COVID-19 pandemic and extended closure of the Canada–United States border, the league announced that the Capitales (along with the Trois-Rivières Aigles) would be unable to compete for the 2020 season (which was later cancelled).

On July 30, 2021, Équipe Québec hosted the New York Boulders at Stade Canac and won the game 10–8 in front of a full house of 2,800 spectators, the maximum number allowed during sanitary measures.

On September 12, 2021, Équipe Québec qualified for the playoffs, and then faced the Washington Wild Things in the best-of-five Frontier League Division Series.

The crowd of 3,750 gathered at Stade Canac during Game 3 at home represented more than 900 people than the number allowed due to sanitary measures, and Québec were able to pull a 3–2 win over the Wild Things.

Équipe Québec finished the season 1st place in the Atlantic Division with a record of 52 wins and 44 losses with an average of 2,288 fans in 24 home games, including the playoffs.

On September 18, 2022 during Game 4 of the FLCS, the Capitales won their 8th championship in franchise history over the Schaumburg Boomers, in front of their fans thanks to a walk-off sacrifice-fly in the bottom of the 9th inning by Ruben Castro.

The 2023 season was also notable for the Capitales drawing 166,916 people to its ballpark for an average of 3,035, the highest total in franchise history.

They’ve sold out 21 out of their 48 home games and set a franchise record for the most consecutive sellouts, with 16 in a row.
