The regular season is eight to nine weeks long, depending on the conference, and, as of 2011, opens on the Labour Day weekend. Teams play between 12 to 16 regular season games, depending on conference or division, with teams typically playing a home and home series with every other team in their conference or division. All regular season games are in-conference. Following the conclusion of the regular season, the Joe Johnson Memorial Trophy is awarded annually to the Player of the Year in CIS men's soccer.
After the regular season, single eliminationplayoff games are held between the top teams in each conference to determine conference champions. In the Canada West and Quebec conferences, the top four teams qualify for the playoffs, with the fourth and first seeded teams playing one match and the third and second seeded teams playing another. The two winning teams then play for the conference championship. Because there are more teams in the Atlantic conference, the top six teams qualify, with the top two teams receiving a first-round bye. The sixth and third seeded teams play one match and the fifth and fourth seeded teams play another. The winning teams then go on to play the top two seeded teams, with the lowest remaining seed playing the first seeded team and the highest remaining seed playing the second seeded team. The winners of these two semi-final matches then play for the Atlantic conference championship.
The Ontario playoff system operates much like the Atlantic one, except it functions for both the West and East divisions. The top six teams from each division (twelve total) qualify for the playoffs, with the top two seeds of each division receiving byes. The champions of each division then play for the OUA conference championship. Because the OUA has 12 teams competing, it necessitates a longer post-season schedule. Consequently, the first round of the playoffs in the OUA occurs during the same week that each of the other three conferences are playing their last regular season games. The four conference champions automatically qualify for the CIS Men's Soccer Championship.
The CIS Men's Soccer Championship, first established in 1972, features eight teams in single elimination matches to determine a national champion. The championship hosts 11 games over four days at a predetermined host venue. The host team is automatically qualified for the tournament, as is each of the conference champions. Another berth is awarded to the second-place finisher in the Ontario conference and the two remaining spots are awarded to the second-place finisher in each of the remaining conferences. If an OUA team is hosting, three teams from the OUA qualify and the previous year's championship seeding would determine which conference would lose the final spot.
The CIS is not geared towards producing professional soccer players, though some CIS players have turned pro. CIS players are not eligible for the MLS SuperDraft, but are able to be selected in the USL Draft. Most CIS players are 21 or 22 upon leaving university and are too old to be considered prospects by most pro teams. Top players in high schools and sports academies may opt not to play in CIS so that they can turn pro directly. Despite this, some CIS alumni in the pro ranks include Haidar Al-Shaiban (Western), Nana Attakora (York), Gabe Gala (Toronto), Srdjan Djekanović (UBC).
