There were seven participating teams in the 2016 Under-19 Provincial Championship. These teams played each other twice over the course of the season, once at home and once away. Teams received four points for a win and two points for a draw. Bonus points were awarded to teams that scored four or more tries in a game, as well as to teams that lost a match by seven points or less. Teams were ranked by log points, then points difference (points scored less points conceded).
