The Canadian Football League presents a distinct betting landscape shaped by its unique rulebook. The larger field, three-down format, and 20-second play clock produce higher-scoring, more volatile games than its NFL counterpart, with totals regularly landing in the 45-55 range and blowouts occurring more frequently than casual bettors expect. Twelve-man rosters, rouge points, and the ability for any player to go in motion toward the line before the snap create offensive wrinkles that sharp bettors can exploit when books are slow to adjust. The league's nine-team structure and 18-game regular season — running from mid-June through early November, with the Grey Cup typically in late November — means the sample size is small, and market depth is considerably thinner than major North American sports.

That limited market depth has direct implications for vig. CFL lines generally carry wider margins than NFL sides and totals, primarily because books see lower handle volume and have less incentive to sharpen their numbers. Spreads of -110/-110 are less common; bettors will frequently encounter -112 or -115 on both sides, particularly at recreational-focused sportsbooks. Prop and alternate line markets, where available, tend to carry even steeper juice. However, competition among books does tighten margins on marquee matchups — Labour Day Classic rivalries, playoff games, and the Grey Cup typically see the sharpest lines of the season, as public interest and betting volume spike.

Several factors move CFL odds in ways bettors should monitor closely. Roster turnover is constant, with players frequently shuffling between the CFL, NFL practice squads, and the UFL, making injury and transaction reports essential reading. Weather is a major variable at open-air stadiums in Winnipeg, Regina, and Edmonton, where late-season wind and cold can suppress scoring dramatically. Home-field advantage also carries more weight than in the NFL — teams like Saskatchewan routinely outperform their road records by significant margins. Bettors who track quarterback rotations, short-week scheduling, and early-season line movement before books calibrate to true team strength will find the most exploitable edges.

Frequently Asked Questions

What are the best CFL lines today?

The table below shows which sportsbook has the best available price on each side of every upcoming CFL event. Line shopping across multiple books can save you 1–3% per bet compared to sticking with a single sportsbook.

What is vig (vigorish) in sports betting?

Vig — short for vigorish, also called juice or overround — is the margin a sportsbook builds into its odds. It's the difference between the true probability of an outcome and what the odds imply. Lower vig means you keep more of your winnings on every bet. For example, a standard -110/-110 line has about 4.76% vig.

How often is this data updated?

We pull fresh odds from The Odds API every hour, on the hour (UTC). Each snapshot captures the latest lines from every sportsbook that has posted odds. The timestamp at the top of the page shows the most recent refresh.

How is the vig grade calculated?

Each sportsbook is graded on average vig: A+ (under 2%) is exchange-level pricing, A (2–3%) very competitive, B+ (3–4%) above average, B (4–5%) the industry standard, C+ (5–6%) slightly below average, C (6–7%) below average, D (7–8%) high vig, D− (8–10%) very high, F (10%+) predatory.

Why does lower vig matter for bettors?

Lower vig directly impacts your long-term returns. A bettor placing $1,000 per week at a book with 4% vig loses roughly $40/week to the house edge. At 2% vig, that drops to $20/week — a $1,040 difference over a year. For serious bettors, shopping for lower vig is one of the most reliable ways to improve profitability.

What sportsbooks do you track?

We track both regulated US sportsbooks (DraftKings, FanDuel, BetMGM, Caesars) and offshore books (Bovada, BetOnline, MyBookie, BetUS, LowVig.ag, BetAnything). Data comes from The Odds API, which aggregates real-time lines from licensed sources.

How We Calculate These Numbers

Data Source
All odds on this page come from The Odds API, which aggregates real-time lines from licensed US and offshore sportsbooks. We track moneyline, spread, and totals markets across every sport with active betting lines.
Update Frequency
We pull a fresh snapshot of every tracked market every hour, on the hour (UTC). Each snapshot captures the latest lines from every sportsbook that has posted odds for a given event. The timestamp at the top of each page tells you exactly when the data was last refreshed.
Vig Calculation
Vig (short for vigorish, also called juice or overround) measures the margin a sportsbook builds into its odds. We calculate it by converting the odds on each side of a market to implied probabilities, summing those probabilities, and subtracting 100%. For example, a market priced at -110/-110 implies 52.38% on each side — a total of 104.76%, meaning a vig of 4.76%. Lower vig means better value for bettors because you keep more of your winnings.
Per-Market Breakdown
We compute vig separately for each market type: moneyline (h2h), point spreads, and totals (over/under). The "average vig" shown for each sportsbook is the mean across all market types weighted by the number of events sampled in each market.
Grading Scale
Every sportsbook receives a letter grade based on its average vig: A+ (under 2%) is exchange-level pricing. A (2–3%) is very competitive. B+ (3–4%) is above average. B (4–5%) is the industry standard — a -110/-110 line is 4.76%. C+ (5–6%) is slightly below average. C (6–7%) is below average. D (7–8%) is high vig. D− (8–10%) is very high vig. F (10%+) is predatory pricing. See the full Vig Index Methodology for formulas, worked examples, and known limitations.
Trend Tracking
We store daily snapshots for 30 days, allowing us to show 24-hour and 7-day vig trends. A downward trend (improving) means sportsbooks are tightening their lines — often in response to increased competition or higher betting volume as a season heats up.
