Sports Betting Explained

Once you've got an account set up - covered in How to Bet Online in Canada - the next thing that trips up new bettors isn't the platform, it's the market. Sportsbooks offer a wide menu of ways to bet on the same game, and each one has different mechanics, different risk, and different payout structure. This guide walks through every bet type you're likely to encounter on a Canadian sportsbook, in the order you'll probably learn them.

Odds formats: decimal vs. American

Before any bet type makes sense, you need to be able to read the odds attached to it. Canadian sportsbooks most commonly default to decimal odds, though most platforms let you switch to American odds in account settings, and you'll see both referenced across betting content generally.

Decimal odds (e.g., 2.50) show your total return per dollar staked, including your original stake. A $10 bet at 2.50 odds returns $25 total - $15 profit plus your original $10 stake back. To find implied probability, divide 1 by the decimal odds (1 ÷ 2.50 = 40%).

American odds use a plus/minus format. A negative number (e.g., -130) shows how much you need to stake to win $100 profit - a -130 bet requires a $130 stake to profit $100. A positive number (e.g., +150) shows how much profit a $100 stake would win - a +150 bet pays $150 profit on a $100 stake. Favorites carry negative odds, underdogs carry positive odds.

Moneyline: picking the winner

The simplest bet type: pick which team or player wins the game outright, with no point spread involved. If Toronto is priced at -130 and Ottawa at +110, a moneyline bet on Toronto wins if Toronto wins the game by any margin, and a bet on Ottawa wins if Ottawa wins by any margin - the odds simply reflect which side is favored. Moneyline betting is especially common in sports without a standard point spread, like hockey and baseball, though it's available across every major sport.

Point spread: betting on the margin

A point spread "handicaps" the favorite by a set number of points, requiring them to win by more than that margin for a spread bet to pay out (and allowing the underdog to lose by less than that margin, or win outright, and still cover). If Toronto is -6.5 against Ottawa, a spread bet on Toronto only wins if Toronto wins by 7 or more points; a spread bet on Ottawa wins if Ottawa loses by 6 or fewer points, ties, or wins outright. Spreads are typically priced close to even odds on both sides (commonly around -110 for each side in American odds, or roughly 1.91 in decimal), with the point spread itself - rather than the odds - doing the work of balancing the bet. Spreads are the dominant bet type in football and basketball specifically, where scoring margins are large enough to make a moneyline-only market less interesting for bettors on either side.

Totals (over/under): betting on combined scoring

A totals bet doesn't require picking a winner at all - instead, the sportsbook sets a projected combined score for both teams (e.g., 5.5 in an NHL game), and you bet on whether the actual combined score will land over or under that number. Totals are popular precisely because they don't require an opinion on which team is better, only on how the game is likely to be played (high-scoring vs. defensive, for instance).

Parlays: combining multiple bets

A parlay (sometimes called an accumulator) combines two or more individual selections into a single bet, with all selections required to win for the parlay itself to pay out. In exchange for this significantly higher risk, parlay odds multiply together, producing a much larger potential payout than any of the individual bets would offer alone. A three-leg parlay with each leg at roughly even odds might pay out around 6-to-1 or higher, compared to roughly even money for any single leg - but the probability of hitting all three drops correspondingly. Parlays carry a meaningfully higher combined house edge than the equivalent single bets, a mechanic covered in more depth in Sports Betting Strategy.

Teasers

A teaser is a specific type of parlay, mostly available in football and basketball, that lets you adjust the point spread or total on each leg in your favor - for example, moving a -6.5 spread to -0.5 - in exchange for lower overall payout odds than a standard parlay. Teasers are a niche, more advanced bet type; most new bettors won't encounter them regularly, but they're worth recognizing if a sportsbook's menu references them.

Player and team props

A "prop" (proposition bet) is any bet on a specific occurrence within a game that isn't tied directly to the final score or margin - a player recording over or under a specific number of points, a team scoring first, the length of a specific in-game event. Props have become an increasingly large share of overall sportsbook betting volume, especially for major events, precisely because they let bettors wager on specific storylines or players rather than only the game outcome. Props typically carry a higher built-in vig than standard markets, since they're often lower-volume and harder for the sportsbook to price with the same confidence as a mainstream moneyline or spread.

Same-game parlays

A specific and increasingly popular parlay format that combines multiple prop or market selections from within a single game - for example, a specific player scoring plus the game going over the total plus a specific team winning, all bundled into one bet. Same-game parlays carry the combined vig of a standard parlay, and the individual legs within a single game are often statistically correlated in ways that aren't always reflected cleanly in the combined price, which is worth understanding before treating a same-game parlay's payout odds as a precise reflection of true combined probability.

Futures

A futures bet is placed on an outcome that won't be determined until well after the bet is placed - a team to win a championship, a player to win an end-of-season award. Futures odds shift over the course of a season as team and player performance becomes clearer, and futures bets tie up your stake for the duration, with no opportunity to change your mind once placed (outside of cashing out early, where offered - see below).

Live (in-play) betting

Live betting lets you place wagers on a game that's already underway, with odds updating continuously to reflect what's actually happening on the field or ice. This has become one of the most popular formats on modern sportsbooks specifically because it lets bettors react to how a game is unfolding, rather than committing entirely before kickoff. Live betting requires faster decision-making than pre-game markets, and odds can shift meaningfully within seconds around a key play, which is worth being aware of if you're new to the format - confirm your bet slip reflects the odds you actually intended to accept before submitting, since a brief delay can mean the live price has moved.

Cash out

Many sportsbooks offer a "cash out" feature, letting you settle an already-placed bet early - before the game or event concludes - for a value calculated by the sportsbook based on the bet's current likelihood of winning. This can lock in a partial profit on a bet that's going well, or limit a loss on one that's going poorly, but the cash-out value always carries a built-in margin in the sportsbook's favor compared to the bet's true expected value at that moment, similar in spirit to the standing vig on any other market.

Reading an actual bet slip

Whatever bet type you select, your bet slip will consistently show four things: the specific selection (e.g., "Toronto -6.5"), the odds in your chosen format, your stake, and the potential payout, calculated automatically and updated in real time as you adjust your stake. For a parlay, the slip will list each leg individually along with the combined odds for the full parlay. Always review the full slip - selection, odds, and stake - before confirming, particularly for live bets where odds can shift between when you select a market and when you actually submit the bet.

A quick reference table

Alternate lines and alternate totals

Most sportsbooks offer alternate versions of the standard spread or total for a given game - the same market, shifted to a different number, with the odds adjusted accordingly. If the standard spread is Toronto -6.5 at roughly even odds, the sportsbook might also offer Toronto -3.5 at worse odds (since it's an easier line to cover) and Toronto -9.5 at better odds (since it's harder to cover). Alternate lines let bettors express a more specific opinion about a game's likely margin than the single standard line allows, and they're worth exploring once the standard bet types feel familiar, particularly for bettors with a strong view on how a specific game is likely to play out.

Round robin bets

A round robin is a way of playing multiple smaller parlays from a single group of selections, rather than committing to one all-or-nothing parlay. If you select four teams for a round robin of two-team parlays, the system automatically creates every possible two-team combination from those four selections (six combinations in total) and places an equal stake on each. This structure lets a bettor benefit from some legs winning even if not every selection in the group does, trading the larger payout of a single big parlay for a spread of smaller, more achievable ones. It's a more advanced format, but worth knowing about if a sportsbook's menu references it.

Boosted odds and profit boosts

Many operators periodically offer "boosted" odds on specific markets - a moneyline or prop temporarily priced better than the operator's own standard line, usually as a promotional tool to draw attention to a specific game or market. These can represent genuine, if modest, added value when used selectively, but it's worth applying the same scrutiny here as with any bonus offer: a boost is only worth chasing if it's on a bet you'd have reasonably considered anyway, not a reason to bet on something you otherwise wouldn't. Our Welcome Bonus Guide covers the broader principle of evaluating promotional offers on their real terms rather than their headline appeal.

How and why odds move

Sportsbook odds aren't static from the moment a market opens until the event starts - they shift in response to new information (injury news, weather for outdoor sports, lineup changes) and, at many operators, in response to betting volume itself, as a book adjusts a line to balance action on both sides and manage its own risk. A line moving from -6.5 to -7.5 on a football spread, for instance, might reflect genuine new information about the favorite's likely performance, or it might simply reflect heavier betting volume on one side that the sportsbook is trying to balance.

Significant, rapid line movement not clearly tied to public news is sometimes referred to as a "steam move," often associated with a wave of well-informed or high-volume betting activity hitting a market at once. Recognizing that lines move for different reasons - information versus volume - is part of what separates more advanced bettors from those simply reacting to whatever number happens to be posted at the moment they check.

Common beginner mistakes reading a bet slip

Not double-checking which side of the spread you selected. It's a common early mistake to tap the wrong team on a close spread, particularly on a mobile interface - always confirm the selection text on your bet slip matches what you intended before submitting.

Confusing "total" bets with team-specific totals. A standard totals bet covers the combined score of both teams; some sportsbooks separately offer team totals (betting on a single team's individual score, over or under). These look similar on a bet slip but are entirely different markets.

Assuming odds are locked in before submitting. Especially for live bets, the odds you see when selecting a market can shift slightly by the time you confirm your slip if there's any delay. Most platforms will flag a price change and ask for confirmation before accepting the bet at a new number - don't assume the originally displayed odds are guaranteed until the slip is actually confirmed.

Overlooking bet slip restrictions. Some markets have minimum or maximum stake limits, or restrictions on combining certain bet types into a single parlay. If a bet won't submit, check for a restriction notice on the slip itself before assuming it's a technical error.
