BC Soccer originally looked into the possibility of starting a "Regional Tier 3" league in their 2016 Strategic Plan,[3] with the goal of beginning in 2018 with eight teams.[4] However, nothing came to fruition due to insufficient interest from clubs.[5][6] In June 2019, they announced their intention to begin play in 2021 with at least six clubs.[7] Teams would need to commit for three years minimum and field teams in both the male and female divisions.[5] The proposed league would be open to professional clubs fielding reserve sides, provided they are not branded with "Reserves" or "U-23" in their team name.[8][9]
In January 2021, the league was rumoured to be launching later that year with six or eight teams, including a development team from the Major League Soccer club Vancouver Whitecaps FC.[10] On October 5, 2021, the league was officially announced by BC Soccer to begin play in May 2022.[11][12] The inaugural league began on May 22, with the Championship Final occurring on August 1 (British Columbia Day), with seven clubs participating in the first season.[13][14] It was announced that with the creation of the league, the Juan de Fuca Plate, which was previously awarded to the top BC-based Premier Development League team in head-to-head matches, would now be awarded to the League1 BC club that accrued the greatest number of points across both the men's and women's divisions in an aggregate table.[15][16] In addition, a cedar trophy was created to be awarded to both the men's and women's division champions.[17] In November 2022, it was confirmed that the league winner would qualify for the following season's Canadian Championship, the national cup tournament.[18] For the 2023 season, the league announced its first expansion club (Harbourside FC) bringing the league up to eight clubs.[19]
On December 1, 2023, Canadian Soccer Business acquired L1BC from BC Soccer. CSB have owned League1 Ontario since 2018 and now oversee the day-to-day operations of both leagues.[20] For the 2024 season, another expansion club joined, however, two original clubs withdrew from the league, bringing the total back to seven. For 2025, two additional clubs joined, bringing the league to nine clubs.[21]
Competition format
The L1BC regular season lasts approximately two months, from late May to late July. Teams play each other team home and away for a total of 12 matches in 2022. The regular season champion and runner-up advance to a single match final where the winner is crowned finals champion.
Note: There is no clear information from CSA about tier of U.S. based leagues which have Canadian clubs. In terms of historical information, they have been deployed as tier 3 league as USSF have done.
