A look at the Canadian Premier League format and roster rules:
The seven teams will each play 28 regular-season games, 14 home and 14 away, in a season split in two, with spring and fall champions meeting to decide the year's overall winner.
The spring season will run from April 27 to July 1 with all seven clubs playing 10 matches. The table will then be reset for the fall season, which will run from July 6 to Oct. 19. Clubs will play 18 matches in the second season.
The spring and fall champions will meet to decide the overall league winner. If the same club wins both seasons, it will meet the club with the next most cumulative points across both seasons in the final.
