CFL

Section 1: Introduction

The Canadian Football League (CFL) is the professional football league in Canada and the second-oldest professional gridiron football league in North America. The Grey Cup, the CFL's championship trophy, has been awarded since 1909 — predating the NFL's first championship by over a decade.

The CFL currently features 9 teams organized into two divisions: the West Division (BC Lions, Calgary Stampeders, Edmonton Elks, Saskatchewan Roughriders, Winnipeg Blue Bombers) and the East Division (Hamilton Tiger-Cats, Montreal Alouettes, Ottawa Redblacks, Toronto Argonauts). The regular season runs from June through November, with the Grey Cup championship game held in late November.

Canadian football shares common origins with American football, both evolving from rugby in the late 19th century. However, Canadian football developed its own distinct identity with rules that create a fundamentally different game: a larger field, 12 players per side, only 3 downs, unlimited pre-snap motion, and the unique single-point (rouge) scoring play.

Key Differences from NFL/NCAA Rules

• 3 downs to advance 10 yards — NFL/NCAA use 4 downs
• 12 players per side — NFL/NCAA use 11
• Larger field: 110 × 65 yards with 20-yard end zones — NFL/NCAA is 100 × 53⅓ with 10-yard end zones
• Unlimited backfield motion toward the line of scrimmage — NFL allows only 1 player in motion (not toward the line)
• No fair catch — instead, a 5-yard "no yards" zone protects punt returners
• Rouge (single point), narrowed for 2026 — under Rule 4, Section 2, Article 4, awarded only when a kick settles in the end zone and the returner fails to bring it out; no longer awarded for a kick that exits the end zone untouched
• Automatic 35-second play clock, new for 2026 — reverting to a 20-second clock in the final three minutes of each half and throughout overtime (Rule 1, Section 7, Article 4); NFL uses 40 seconds throughout
• No more tie games in the regular season, new for 2026 — an unlimited series of alternating two-point convert attempts now settles regular-season games still level after two overtime mini-games (Rule 1, Section 8)
• Goal posts on the goal line — NFL moved them to the back of the end zone in 1974

Section 2: Equipment

The Football

The CFL ball is slightly different from the NFL ball:

• Size: Slightly larger circumference than the NFL ball — the CFL ball has a slightly more pronounced pointed shape
• White stripes: Like the NCAA ball, the CFL ball features white stripes on each end for visibility, especially at night games. The NFL ball has no stripes.
• Weight: 14 to 15 ounces — same as NFL
• Inflation: 12.5 to 13.5 psi

Player Equipment

• Helmet: Mandatory with face mask, meeting CSA (Canadian Standards Association) or NOCSAE standards
• Shoulder pads: Required for all players
• Mouthguard: Mandatory
• Thigh pads, knee pads, hip pads: Required
• Shoes: Cleats appropriate for the playing surface

Uniforms

• Jersey numbers: Under Rule 6, Section 4, Article 4 (Eligibility of Receiver), Team A players are identified by playing number — eligible receivers wear numbers 0-49 and 70-99, ineligible receivers wear numbers 50-69. Rule 4, Section 5, Article 2 applies the same numbering to identify Line Players.
• Home team: Wears dark jerseys (same convention as NFL)
• Player names: Required on the back of jerseys

Section 3: Playing Area

The Field — Significantly Larger Than NFL

The CFL field is the largest playing surface in professional gridiron football:

• Length: 110 yards (100.58 meters) between goal lines — 10 yards longer than NFL/NCAA
• Width: 65 yards (59.44 meters) — nearly 12 yards wider than NFL/NCAA's 53⅓ yards
• End zones: 20 yards deep — TWICE as deep as NFL/NCAA's 10-yard end zones
• Total playing surface: 150 yards × 65 yards = 9,750 square yards (vs NFL's 6,400 square yards)
• Impact: The wider, longer field with deeper end zones creates more space, favoring passing offenses and speed players. It is one of the defining characteristics of Canadian football.

Goal Posts

• Location: On the goal line, not at the back of the end zone. The NFL moved goal posts to the end line in 1974; the CFL kept them on the goal line.
• Width: 18 feet 6 inches between the uprights — same as NFL
• Crossbar height: 10 feet — same as NFL
• Impact: With goal posts on the goal line, they become an obstacle during play in the end zone. Passes and players can ricochet off the posts. Under Rule 5, Section 4, Article 13 (Kicked Ball Striking Goal Post Assembly), if a kick strikes the post and does not result in a score, the ball is next scrimmaged by the opponent at their 40-yard line.

Dead Line

The CFL has a unique field marking:

• Dead line: A line 20 yards behind each goal line, marking the back of the end zone. In the NFL, this is simply the end line. In the CFL, a ball carrier in the end zone who is tackled or goes out of bounds behind the dead line results in either a safety (if it's their own end zone) or a rouge (if it's the defending end zone).

Hash Marks

• Width: 51 feet apart (17 yards from each sideline) — wider than both NFL (23.58 yards from sideline) and NCAA (13.33 yards from sideline)
• Impact: The wider hashes create even more "short field" than NCAA and affect play design

Section 4: Players & Officials

Team Composition — 12 Players

This is one of the most fundamental differences from American football:

• On the field: 12 players per side — one more than NFL/NCAA's 11
• Extra player: Typically an additional defensive back or slotback/receiver. The wider field demands more coverage.
• Roster: 46-player active roster, plus a practice roster
• Canadian ratio: The CFL mandates a minimum number of Canadian (non-import) players on the roster and in the starting lineup, ensuring Canadian talent development

Offensive Positions

• Quarterback: Same role as NFL
• Running backs: Halfback (tailback) and fullback, same as NFL
• Slotbacks: Unique to Canadian football — positioned between the offensive line and the wide receivers, often used in motion. Functions similarly to a slot receiver or H-back in NFL terminology.
• Wide receivers: Typically 2, positioned near the sidelines
• Offensive line: 5 linemen (center, 2 guards, 2 tackles) — same as NFL. Rule 4, Section 5, Article 1 (Seven Players on Line) requires at least seven Team A players to be Line Players at the snap, and Team A can never have more than five players in backfield positions.

Game Officials

The CFL uses a crew of 7 officials, similar to the NFL. The CFL also employs a Command Centre (Replay Centre), per Rule 1, Section 13 (Replay Overview) and Rule 10, for video review of plays, similar to the NFL's replay system.

Canadian Player Ratio

A unique CFL regulation:

• Each team must have a minimum of 21 Canadian (national) players on its 46-player roster
• A minimum of 7 Canadian players must be in the starting lineup (offense or defense)
• Players are classified as "national" (Canadian citizen or permanent resident) or "international" (all others)
• This rule has no equivalent in the NFL or any other major North American professional league

Section 5: Rules of Play

Three Downs — The Defining Rule

Canadian football uses 3 downs to advance 10 yards, compared to 4 downs in American football. This single rule change has the most profound impact on the game:

• More passing: With only 3 attempts to make 10 yards, teams pass the ball significantly more. Running plays carry higher risk because a failed run on second down creates a near-certain punt on third down.
• Second down is critical: If a team fails to gain significant yardage on first down, second down becomes a must-convert situation. In the NFL, teams can afford a failed first down because third down is effectively the "money down."
• More punting: Teams punt on third down far more often than NFL teams punt on fourth down
• Impact on strategy: Offenses are more aggressive, defenses must defend the pass more frequently, and the game features more total passing yards per game than NFL

Pre-Snap Motion — Unlimited Backfield Motion

Another dramatically different rule:

• CFL: ALL offensive backfield players (everyone except the 5 offensive linemen and the quarterback) may be in motion toward the line of scrimmage at the snap
• NFL: Only ONE player may be in motion at the snap, and they may NOT move toward the line of scrimmage
• Impact: CFL offenses use "waggle" motions where multiple receivers and backs charge toward the line at the snap, creating a dynamic pre-snap sequence that generates momentum and confuses defensive assignments

Play Clock — Automatic 35 Seconds, Reverting to 20 Late in Each Half and in Overtime (New for 2026)

The CFL's Board of Governors approved a change to the play-clock structure on May 12, 2026, following recommendations from the Rules Committee (head coaches, team presidents, the Canadian Professional Football Officials Association, and the CFL Players' Association). The change is codified in Rule 1, Section 7, Article 4 (Play Clock) of the 2026 CFL Official Playing Rules, with a related change to Rule 1, Section 7, Article 3 (Game Clock).

• General play: Under Rule 1, Section 7, Article 4, "after most plays a 35-second play clock will start automatically upon a signal from the covering official that the play is over and the next play may take place" — creating consistency and speeding the pace of play between snaps, up from the previous flat 20-second clock.
• 20-second play clock retained for specific situations: Rule 1, Section 7, Article 4 directs the Referee to instead start a 20-second play clock for the play after a kickoff, after a touchdown has been scored, after the application of penalties, after a change of possession, after a TV or team timeout, after an injury or equipment delay, after a Team Challenge or Replay Centre-initiated review, or after any other administrative delay; for every play after the three-minute warning in each half and for every play in overtime; and any time the officials deem it necessary.
• Game clock interaction: Under Rule 1, Section 7, Article 3 (Game Clock), if the game clock is running and the ball is not snapped before 3:00 remains in a half, the clock stops at 3:00 and the three-minute warning is given; the game clock then starts on the snap of the first play following the warning.
• Back-to-back clocks: On a kickoff following a convert or field goal with no commercial break, the timer runs back-to-back 35-second play clocks, and the team must kick the ball before the second 35-second play clock reaches zero.
• Kneel-out, new for 2026: Rule 1, Section 7, Article 3 now lets Team A end a half by declaring to the Referee that it will "kneel out," when it has a first down and 40 or fewer seconds remain on the clock, so the offense need not run multiple kneel-downs to exhaust the clock.
• NFL comparison: The NFL uses a 40-second play clock from the end of the previous play (or 25 seconds after certain stoppages), applied uniformly across all four quarters — the CFL's late-half and overtime reversion to a 20-second clock has no NFL equivalent.

No Fair Catch — The 5-Yard Halo

• CFL: There is no fair catch. Instead, the kicking team must give the punt returner a 5-yard "no yards" zone. No member of the kicking team may come within 5 yards of the returner until the ball is touched.
• Penalty: Violation of the no-yards rule results in a 15-yard penalty from the point of the infraction (or 5 yards if the ball is not caught)
• Impact: Punt returns are far more common and more exciting in the CFL because the returner always has the option to run. There are no "free catches" — every punt is a potential return play.

Overtime — Ties Eliminated in the Regular Season for 2026

Rule 1, Section 8 (Tie Game) of the 2026 CFL Official Playing Rules governs overtime procedure:

• Mini-game format: If the score is tied at the end of regulation, a coin toss determines the first team, which scrimmages the ball at the opponent's 35-yard line and may advance by consecutive series of downs until it scores or loses possession; a resulting touchdown must be followed by a two-point convert attempt scrimmaged from the 3-yard line. The second team then scrimmages at the same 35-yard line and proceeds the same way.
• Second mini-game: If still tied, a second mini-game is played at the opposite end of the field, with both teams again scrimmaging from the 35-yard line. There is only one coin toss in overtime — after the first mini-game, the choice of which team starts on offense alternates between the teams.
• Playoffs and Grey Cup: If still tied after the second mini-game, additional mini-games are played, alternating the end of the field used, until a winner is determined.
• Regular season — ties eliminated for 2026: Under the amended Rule 1, Section 8, a regular-season game still tied after the second mini-game no longer ends in a tie. Instead, the teams stay at the same end of the field and alternate two-point convert attempts from the 3-yard line — the first team attempts to score, then the second team attempts to score, and if still tied this series continues, at that same end of the field, until one team has scored more points than the other after each has had an equal number of opportunities to score.
• Overtime timeouts, new for 2026: Rule 1, Section 7, Article 7 (Team Time Out) now grants each team one 15-second timeout in overtime, in addition to the two 30-second timeouts available during regulation — a stoppage that did not previously exist in the CFL's overtime procedure.

Kicked Ball Out of Bounds

• If a punt goes out of bounds, the receiving team may choose to take the ball where it went out of bounds OR at the spot from which it was kicked — whichever is more advantageous. This is unique to the CFL.

Section 6: Scoring

Point Values

• Touchdown: 6 points — same as NFL/NCAA
• Convert (PAT): 1 point for a kick from the 32-yard line (NFL kicks from the 15-yard line, NCAA from the 3-yard line). The CFL's longer PAT distance makes it a more meaningful play.
• Two-point conversion: 2 points, from the 3-yard line — same as NFL/NCAA
• Field goal: 3 points — same as NFL/NCAA
• Safety: 2 points — same as NFL/NCAA

The Rouge (Single Point) — Narrowed for the 2026 Season

The rouge or single point remains one of the most distinctive scoring plays in Canadian football, but the 2026 CFL Official Playing Rules narrow when it can be awarded. Under Rule 4, Section 2, Article 4 (Single Point or Rouge), the CFL's Board of Governors eliminated the single point previously scored when a kicked ball goes directly out of bounds in the opponent's goal area, either in flight or after hitting the ground, with the stated goal of reducing games decided by a missed field goal that still puts a point on the board.

• How it's scored (2026 rule): A single point is awarded to the kicking team only when a punt, missed field goal, or kickoff settles in the receiving team's end zone and the returner fails to run it out of the end zone (or concedes the play).
• No longer a single: Under Rule 4, Section 2, Article 4, a kick that goes directly out of bounds in the opponent's goal area — whether in flight or after hitting the ground — no longer produces a rouge. A related change under Rule 1, Section 9, Article 2 (Kicked Ball Out of Bounds) and Rule 5, Section 4, Article 13 (Kicked Ball Striking Goal Post Assembly) provides that when a kicked ball goes through the opponent's goal area untouched, or strikes the goal post assembly without a score resulting, the ball is instead next scrimmaged by the opponent at their 40-yard line.
• Scenarios that still score a single: the returner is tackled with the ball in the end zone, the returner kneels in the end zone, or the returner fumbles the ball out of the end zone after fielding a kick that settled there.
• Strategy: The rule change removes the guaranteed point kicking teams previously banked by simply sending the ball through the back of the end zone. Punters and placekickers must now get the ball to settle in the end zone to have any chance at a single, since a kick driven directly out of bounds there scores nothing and instead hands the opponent the ball at their own 40-yard line.
• Game impact: Rouges still decide close games, but only on kicks the returner is forced to field and fails to advance out of the end zone — a team trailing by 1 point can still attempt a punt that settles in the end zone for the tying single, but a kick driven directly out of bounds there no longer accomplishes the same thing.
• NFL equivalent: There is no equivalent play in American football. NFL touchbacks are free — no point is scored.

Section 7: Violations & Penalties

Common Penalties

• Offside: 5 yards — same as NFL
• Procedure (false start): 5 yards — same as NFL
• Holding (offensive): 10 yards — same as NFL
• Pass interference (defensive): Spot foul — same as NFL (unlike NCAA's 15-yard maximum)
• Pass interference (offensive): 15 yards — same as NFL
• Rough play: 25 yards — CFL uses a 25-yard penalty for roughing the passer and other rough play infractions. NFL uses 15 yards.
• No yards: 15 yards if the ball is caught within the 5-yard zone; 5 yards if the ball is not caught. This penalty has no NFL equivalent since the NFL uses the fair catch.
• Time count violation: Under Rule 1, Section 7, Article 5 (Time Count Foul), Team A must put the ball in play before the play clock expires; the penalty is 5 yards, assessed against whichever play clock — 35 or 20 seconds — is in effect at the time.
• Too many players on the field: 10 yards — both teams must have exactly 12 players. This is called more frequently in the CFL because the extra player creates more opportunities for confusion.
• Illegal contact: 10 yards. Defenders cannot contact receivers beyond 5 yards from the line of scrimmage — same as NFL.

Ineligible Receiver & Eligible-Number Designation (New for 2026)

The May 12, 2026 Board of Governors rule changes also adjusted the CFL's ineligible-player rules, under Rule 4, Section 5, Article 3 (Exceptions to the Numbering Requirements) and Rule 6, Section 4, Article 4 (Eligibility of Receiver) of the 2026 CFL Official Playing Rules.

• Numbering: Per Rule 6, Section 4, Article 4, Team A players are identified by playing number — eligible receivers wear numbers 0-49 and 70-99, while ineligible receivers wear numbers 50-69. If the ball is touched by any eligible player, all players of both teams become eligible receivers.
• Three eligible-designated players: Rule 4, Section 5, Article 3 now permits a maximum of three players wearing an ineligible number (50-69) to line up in an eligible position — as an end or in the backfield — after reporting to the Referee before each scrimmage play in which that player wishes to occupy an eligible position, an increase from the previous limit. The Referee informs the opposing team and all officials of the player's number and position; any listed player who enters or remains in the game without reporting must take a position on the line of scrimmage and remains ineligible to catch a pass.
• New penalty outcome: Under Rule 6, Section 4, Article 4, when an ineligible receiver is the first Team A player to catch or deliberately touch a forward pass, the penalty is now 10 yards or an incomplete pass — giving the defense the option to decline the yardage and treat the pass as incomplete instead.

Objectionable Conduct

• Penalty: 25 yards — CFL uses a 25-yard penalty for unsportsmanlike conduct and objectionable behavior, harsher than the NFL's 15 yards
• Taunting: 15 yards + possible ejection
• Disqualification: 2 objectionable conduct penalties = ejection from the game

Coach's Challenge

• Each team receives 1 challenge per game
• If the challenge is successful, the team retains its challenge (similar to NFL's system)
• In the last 3 minutes of each half, all reviews are initiated by the Command Centre (Replay Centre), and Rule 10, Section 2, Article 2 (Automatic Review Triggers) added turnovers on downs, new for 2026, to the list of plays automatically reviewed

Section 8: Safety Considerations

Concussion Protocol

• Independent spotter: The CFL employs independent medical spotters who can stop play to evaluate any player suspected of having a concussion
• Removal requirement: Any player identified with concussion symptoms is immediately removed from the game
• Return to play: A player diagnosed with a concussion must pass a graduated return-to-play protocol and receive clearance from an independent neurologist before returning
• In-game evaluation: Players removed for concussion evaluation must pass a sideline assessment (SCAT tool) before any potential return

Equipment Standards

• Helmet certification: All helmets must meet CSA or NOCSAE standards and be recertified annually
• Face mask requirements: Full face masks required for all positions
• Equipment inspection: Officials conduct pre-game equipment checks to ensure all mandatory padding is properly worn

Weather Considerations

The CFL season extends into late November, when Canadian weather conditions can be extreme:

• Cold weather: The Grey Cup has been played in temperatures below -20°C (-4°F). Outdoor stadiums (e.g., Saskatchewan's Mosaic Stadium, Hamilton's Tim Hortons Field, Winnipeg's IG Field) regularly host games in freezing conditions.
• Field conditions: Snow removal protocols are in place for all outdoor venues. Fields must be maintained to safe playing standards regardless of weather.
• Player safety: Teams are required to provide heated sideline equipment and cold-weather gear. Game officials can delay play for lightning or extreme weather conditions.
• Indoor venues: BC Place (Vancouver) has a retractable roof, eliminating weather concerns for Lions home games.

Player Welfare

• Medical staff: Each team must have certified athletic therapists and a team physician present at all games and practices
• Ambulance: Required on-site at all CFL games
• Practice limits: The CFL limits full-contact practices during the season to protect player health
