League1 Canada (L1C; French: Ligue1 Canada) is the third tier of the Canadian soccer league system. It is overseen by Canada Soccer Business, in partnership with participating provincial member federations. It is below the Canadian Premier League which is the top-tier national league in the country.
League1 Canada is contested by clubs from three regional leagues; League1 Ontario, League1 British Columbia, and Ligue1 Québec for both the men's and women's divisions. Each of these leagues represents the highest level of soccer sanctioned by their respective provinces. Dino Rossi has served as league president since May 2022.
In 2011, the Première ligue de soccer du Québec was established to begin play in 2012, marking the return of semi-professional soccer in the province of Quebec. In 2013, League1 Ontario was founded as a semi-professional league by the Ontario Soccer Association to begin play in 2014 with a men's division, followed by a women's division in 2015. After multiple years of consideration, League1 British Columbia began play in 2022 in both the male and female divisions.
On March 31, 2022, League1 Canada was announced as an alliance of the three existing division three pro-am leagues, aligning the national soccer pathway. L1O and L1BC adopted new logos that day, while the PLSQ transitioned to a common logo and rebranded to Ligue1 Québec in 2023.
From August 12 to 14, 2022, the inaugural Women's Interprovincial Championship was held in Laval, Quebec. The competition was a four-team knockout tournament featuring the champions of each of the three divisions, as well as an additional team from the PLSQ (allocated as host). A.S. Blainville won the inaugural title. The 2023 tournament was held in British Columbia.
In March 2023, League1 Alberta was announced with a five-team exhibition series to be played that summer. The league plans to officially launch for the 2024 season with a minimum of six teams. In June 2023, League1 Prairies was announced with plans for the league to operate between Manitoba and Saskatchewan. The league plans to launch for the 2025 season. 
The league champion for League1 Ontario and League1 British Columbia is determined through a playoffs tournament, while the league champion for Ligue1 Québec is determined through the season standings.
