↑ 7-day trend: Average vig has worsened by 0.12 percentage points over the past week (from 5.04% to 5.16%). Odds margins are widening, meaning bettors are getting less value per wager.
The top 16 books are tightly clustered — only 0.27% separates them. The spread between #1 and #17 is 7.38% — book choice matters significantly for CFL.
The Canadian Football League presents a distinct betting landscape shaped by rules that fundamentally alter scoring dynamics compared to its American counterpart. The wider field, 12 players per side, three downs instead of four, and the rouge (single point) create higher-scoring, more volatile games that regularly push totals into the 50s and beyond. This volatility is a double-edged sword for bettors — it creates value opportunities in totals and spreads, but it also means outcomes swing more dramatically on individual plays. The CFL's eight-team structure limits the number of weekly matchups to just four during the regular season, which concentrates both public and sharp action on a smaller slate and can lead to sharper line movement on marquee games.
Vig on CFL markets tends to run wider than what bettors encounter on NFL or major college football lines. The relatively niche status of the league means sportsbooks face less competitive pressure to tighten margins, and lower overall handle gives them less incentive to sharpen their pricing. Spreads and totals frequently carry standard -110/-110 juice at best, but it's not uncommon to see elevated margins on props, futures, and even some game lines — particularly at books that treat CFL as a secondary offering. Comparing vig across books matters more here than in higher-volume sports, because the difference between -105 and -115 on a side compounds significantly over a 21-week regular season.
The CFL season typically runs from mid-June through early November, culminating in the Grey Cup. Early-season lines often present the most inefficiency, as books and bettors alike adjust to roster turnover, new coaching schemes, and the influx of players cut from NFL camps. Weather becomes a critical variable from September onward, especially for games in Winnipeg, Edmonton, and Saskatchewan, where cold temperatures and wind can suppress scoring and shift totals dramatically. Home-field advantage is pronounced in the CFL — particularly in hostile environments like Mosaic Stadium — and bettors who track roster transactions, short-week scheduling, and the East-West divisional talent gaps can find consistent edges throughout the season.

Frequently Asked Questions
Which sportsbook has the lowest vig for CFL?
Fanatics currently has the lowest average vig for CFL at 4.62%, earning a grade of B.
How do sportsbook odds compare for CFL?
We compare 17 sportsbooks for CFL. The vig ranges from 4.62% (Fanatics) to 12.00% (ReBet).
When do small vig differences matter for CFL?
The top two books (Fanatics and DraftKings) are separated by just 0.00%. While small, this adds up over volume — a bettor placing $1,000/week saves roughly $0 per week by choosing the lower-vig book.
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 three times per day — at 6:00 AM, 2:00 PM, and 10:00 PM 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 a letter scale based on average vig: A+ (under 2%) is exceptional, A (2–3%) is excellent, B+ (3–4%) is above average, B (4–5%) is the industry standard, C (5–6%) is below average, and D (above 6%) indicates high-juice markets.
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, BetAnySports). 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 three times per day — at 6:00 AM, 2:00 PM, and 10:00 PM 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.
