CFL Moneyline Betting Explained: Reading the Odds, Implied Probability, Removing the Margin, Ties and When an Underdog Is Worth It

Updated 20 Oct 2026 · By the BetHubCA Editorial Team

The moneyline is the first bet most people ever make on the CFL, and honestly it's a great place to start. No points to cover, no totals to worry about, just one question: who wins? But there's more going on behind those numbers than most fans realize. A price like −180 or +150 is the book telling you exactly how likely it thinks each team is to win, with its own cut baked in. Once you can read that, you stop betting on who you "like" and start betting on whether the price is fair. Let's break it down properly, like I would for a friend at a tailgate in Regina.

Some ground rules first. You must be 19 or older to bet in most provinces, or 18 in Manitoba and Quebec. This site doesn't accept readers from Ontario or Alberta. Cloudbet, the sportsbook we link to, operates under a Curaçao licence and is not authorized by any Canadian province. All odds, probabilities and stakes on this page are examples made up for teaching, not real lines and not picks.

What a moneyline bet actually is

A moneyline bet is a straight pick of the winner. If your team wins, you get paid at the posted price. If it loses, you lose your stake. The margin of victory doesn't matter at all: a one-point win on a last-second field goal pays exactly the same as a 30-point blowout. That's what makes the moneyline different from the point spread, where the favourite has to win by a set number of points.

A weekend board might look something like this (made-up numbers):

The minus sign marks the favourite and the plus sign marks the underdog. Cloudbet and many international books show decimal odds by default, while most Canadian sports media quote American odds. You'll want to read both comfortably.

Reading American odds

American odds are always built around C$100, even if you bet C$5.

• Negative number (favourite): how much you'd have to bet to win C$100 profit. At −180, you risk C$180 to win C$100. On a C$20 bet, profit is C$20 × 100 ÷ 180 = C$11.11.
• Positive number (underdog): how much profit a C$100 bet would make. At +150, a C$100 bet wins C$150. On C$20, profit is C$30.

An easy way to remember it: minus means "you pay more to win less", plus means "you pay less to win more".

Reading decimal odds

Decimal odds show your total return per dollar, stake included. Multiply your stake by the price and that's what comes back if you win.

• C$20 at 1.556 returns C$31.11 (C$11.11 profit).
• C$20 at 2.50 returns C$50 (C$30 profit).

Converting between the two is simple:

• Positive American to decimal: (American ÷ 100) + 1. So +150 becomes 2.50.
• Negative American to decimal: (100 ÷ the number without the minus) + 1. So −180 becomes 1.556.

Implied probability: what the price is really saying

Every price hides a percentage. For decimal odds it's just 1 divided by the price. For American odds:

• Negative: number ÷ (number + 100). −180 → 180 ÷ 280 = 64.3%.
• Positive: 100 ÷ (number + 100). +150 → 100 ÷ 250 = 40.0%.

That percentage is also your break-even win rate for that price. If you bet Winnipeg at −180 over and over in spots like this, they need to win more than 64.3% of the time for you to come out ahead.

The book's margin, and how to strip it out

Add the two implied chances in the Edmonton–Winnipeg game: 64.3% + 40.0% = 104.3%. A fair coin can't add up to more than 100%, so that extra 4.3% is the sportsbook's margin (people also call it the vig or the juice). It's how the book makes money whichever side wins.

To estimate the book's "true" opinion without its cut, divide each side by the total:

• Winnipeg: 64.3 ÷ 104.3 = 61.6%
• Edmonton: 40.0 ÷ 104.3 = 38.4%

Do the same for the other games:

Why bother? Because it shows you how much margin you're paying, and it gives you a clean baseline. If you think Edmonton actually wins this game 42% of the time, you're disagreeing with the market's 38.4% by nearly four points, and +150 starts to look interesting. If you think they win 38%, the price is about fair and the margin means you lose slowly. Comparing margins across books is useful too: a book running 102.5% on the same game is simply cheaper to bet with.

Ties: the CFL quirk you need to know

In the playoffs and the Grey Cup, CFL games keep going until somebody wins. In the regular season, though, the league's overtime format can still leave a game tied. It's rare, but it does happen, and it matters for how your moneyline bet is settled.

• Two-way moneyline: at many books, if a regular-season game ends in a tie, a two-way moneyline is graded as a push (stake returned) or void. Some books use different rules, so read the house rules for the sport before you bet.
• Three-way moneyline: some books also offer a "1X2" market with home, tie and away. These usually settle on regulation time only, which makes the tie much more likely than in a full-game market, and the prices on each team are longer to reflect that.
• Overtime included: a normal two-way moneyline almost always includes overtime. A three-way regulation market doesn't. Mixing up the two is a classic beginner mistake.

If you've ever wondered why your "Hamilton to win" ticket paid nothing on a game they won in overtime, check whether you accidentally clicked the three-way regulation market.

Moneyline vs point spread: which one to use

The same game can be bet both ways, and neither is always better. Here's how they compare:

A good rule of thumb: if your opinion is "this team wins", the moneyline expresses it directly. If your opinion is "this game is closer than people think", the spread usually fits better. CFL scoring, with singles, long converts and two-point tries, makes close finishes and backdoor scores fairly common, so think about which of those two opinions you really hold. Our CFL point spread guide goes deep on the spread side.

Turning your opinion into a price

To bet moneylines well, you need your own estimate of each team's chance before you look at the board. It doesn't have to be fancy. A basic routine:

1. Start with a power rating. Give each team a number based on point differential, quarterback play and how they've looked against decent opponents over a meaningful stretch, not just last week.
2. Add home field. Home teams in the CFL tend to have an edge from crowd, familiarity and no travel. Many bettors treat it as worth a couple of points, but it varies by stadium and situation.
3. Adjust for the quarterback. No position swings a CFL game more. A backup starting can move a team's chances by a big amount, especially if the offence was built around the starter.
4. Adjust for travel and rest. Canada is huge. A team flying from Vancouver to Montreal on a short week has a real disadvantage. Teams coming off a bye usually get a small boost.
5. Adjust for weather. Strong wind and late-season cold tend to compress scoring and make outcomes more random, which helps underdogs a little.
6. Convert to a percentage. If your rating makes a team a 3-point favourite, a rough rule many football bettors use is that a 3-point favourite wins somewhere around 58% to 60% of the time. Use whatever conversion you trust, but write it down and stay consistent.

Then compare. If your number for Winnipeg is 66% and the book's price implies 64.3% (or 61.6% after margin), you have a slight edge. If your number is 60%, you pass on Winnipeg and maybe look at Edmonton.

What expected value looks like on a moneyline

Expected value is just: (chance of winning × profit) minus (chance of losing × stake). Some made-up examples on a C$20 bet:

Two lessons jump out. First, small differences in your estimate flip a bet from good to bad, so be honest and conservative. Second, the edge on heavy favourites tends to be thin even when you're right, while the risk of a single loss is large. That's why so many experienced bettors find more value on reasonably priced underdogs than on short favourites, although there's no rule that underdogs are always better.

When a CFL underdog is worth a look

The CFL has a reputation for upsets, and some of that is built into the game: only three downs, big returns, a wide field, and singles that can swing a close finish. That variance helps the team that's less likely to win. Situations where underdogs deserve a closer look:

• Public favourites. Popular teams with big fan bases can attract a lot of casual money, which can shorten their price beyond what the matchup justifies.
• Bad weather. Wind and cold make the game sloppier and more random, which narrows the gap between good and average teams.
• Divisional familiarity. Teams that play each other often know each other's tendencies, which can keep games tight.
• Overreaction to one result. A team that got blown out last week often gets a bigger price than it should if the loss was a fluke (turnovers, a missing starter who's now back).
• Quarterback returning. If the market is slow to update after a starter comes back from injury, the price may still reflect the backup.

Keep your expectations realistic. Betting underdogs means losing most of your bets and winning bigger when you hit. If you can't stomach a run of five or six losses, size your bets accordingly.

Line movement and shopping for the best price

Moneyline prices move during the week as injury news, weather forecasts and betting money come in. A team that opens at −150 might close at −175 after its opponent's quarterback is ruled out. A few practical points:

• Early prices can be softer, but they carry more uncertainty about who will play.
• Late prices include more information, so they're usually sharper.
• Beating the closing price regularly is the best sign you're making good bets, even before your results catch up. If you took +150 and the game closed at +130, you got a better deal than the final market.
• Shop between books. On an underdog, getting +160 instead of +150 lowers your break-even from 40.0% to about 38.5%. That's a real difference over a season.

Moneyline parlays: why stacking favourites is a trap

It's tempting to string three heavy favourites together to "make the odds worth it." Look at what actually happens. Three legs at 1.40 each pay 1.40 × 1.40 × 1.40 = 2.74, so a C$20 parlay returns about C$54.88. But if each favourite truly wins 70% of the time, all three win only 0.70 × 0.70 × 0.70 = 34.3% of the time. The fair price for that would be about 2.92. You're paying the margin three times over, and one stumble kills the ticket.

Parlays aren't evil. They're entertainment with a higher house edge. If you enjoy them, keep the stakes small and treat them as a fun side bet, not your main approach. Also be careful with "correlated" parlays like a team's moneyline plus their opponent's under. Many books restrict or reprice those for a reason.

Live moneyline betting

Moneyline prices update during the game. A pre-game favourite trailing by 10 at halftime might suddenly be an underdog. That can create opportunities, but also traps:

• CFL leads are fragile. With quick drives and big returns, 10-point leads disappear regularly. Live markets know this, so don't assume a trailing favourite is a bargain without checking the price.
• Your stream is delayed. The book's data is usually ahead of your TV or stream, and markets get suspended during key plays.
• Have a plan before kickoff. Decide in advance what situation would make you bet live (for example, a favourite you rate highly going down early on a fluky turnover). Don't make it up as the game goes on.
• Cash-out isn't free. Cash-out offers include extra margin. Take one only when the situation has truly changed, such as a quarterback leaving with an injury.

Futures vs game moneylines

Betting a team to win the Grey Cup is a kind of long-range moneyline. The prices are bigger, but your money is tied up for months and the margin on futures markets tends to be higher. Game-by-game moneylines let you react to injuries and form. If you like futures, see our guide on how to bet on the CFL playoffs.

Simple staking for moneyline bettors

Most of the damage bettors do comes from bet size, not bet selection. A sensible approach is flat staking: bet the same amount on every play, usually 1% to 2% of a bankroll you can afford to lose.

Some bettors prefer to stake to win a set amount on favourites (say, to win one unit) and risk one unit on underdogs. That keeps a heavy favourite from risking two or three units on one game. Either way, pick a method and stick to it.

Common moneyline mistakes

• Betting a favourite because "they should win." They probably should. The question is whether they win often enough to justify the price.
• Ignoring the margin. If both sides add up to 106%, you're paying a lot. Find a better book.
• Clicking the three-way market by accident. Know whether overtime counts before you place the bet.
• Not checking the quarterback. A late scratch can make your pre-week price look awful.
• Chasing losses on Sunday night. If the afternoon went badly, the evening game isn't a chance to "get even."
• Not keeping records. Without a log of your bets, prices and closing lines, you can't tell skill from luck.

A quick weekly routine

1. Early in the week, update your power ratings with last week's results.
2. Estimate a win chance for each game and write it down.
3. Check the moneylines at two or three books and strip out the margin.
4. Mark any game where your estimate beats the price by a clear amount, say three percentage points or more.
5. Re-check quarterback status and weather before placing the bet.
6. Log every bet with the price you got and the closing price.

If you enjoy totals too, our CFL over/under tips use a similar build-your-own-number approach.

Taxes and legality, in short

For casual bettors in Canada, winnings are generally not taxed as income, though people who bet as a business can be treated differently. See does Canada tax sports betting winnings for details. Betting rules are set province by province, so check is online betting legal in Canada before you sign up anywhere.

Stay in control

A small moneyline bet can make a mid-season game between two .500 teams a lot more fun. Keep it at that level. Set a limit for the week before the first game kicks off, and stop when you hit it, win or lose.

My take

The CFL moneyline is simple to place but worth understanding properly. Learn to read both American and decimal odds. Convert every price to an implied chance and strip out the margin so you know what the market really thinks. Know how ties and three-way markets are settled. Build your own estimate of each team's chance before you look at the board, and only bet where the price beats your number. Be wary of piling favourites into parlays, keep your bets flat and small, and log everything. Do that, and you'll be betting with your head instead of your jersey.
