Question 1

What do plus and minus signs mean in sports betting odds?

Accepted Answer

In American (moneyline) odds format, a minus sign (e.g., -150) indicates the favourite and shows how much you need to bet to win $100 in profit. A plus sign (e.g., +130) indicates the underdog and shows how much profit you'd win on a $100 bet. For example, if you bet $150 on a -150 favourite and win, you'd receive your $150 stake back plus $100 profit. If you bet $100 on a +130 underdog and win, you'd receive your $100 back plus $130 profit. Most Canadian sportsbooks display decimal odds by default, but you can usually switch to American odds in your account settings. This is particularly useful when betting on MLB or NFL markets where American-style moneyline odds are most commonly referenced.

Question 2

How are sports betting odds calculated in Canada?

Accepted Answer

Bookmakers in Canada calculate odds through a combination of statistical modelling, historical data analysis, and real-time market adjustments. Their trading teams and proprietary algorithms assess the probability of every possible outcome, then set odds that reflect those probabilities while building in a margin (the "vig" or "juice") that ensures profitability regardless of the outcome. As bets are placed by the public, bookmakers may adjust their odds to balance their liability across both sides of a market. This is why odds can change between when you first see them and when the event begins. The primary goal of any odds compiler is to create a balanced book that generates consistent margin regardless of the result.

Question 3

Is sports betting legal in Canada?

Accepted Answer

Yes, sports betting is fully legal in Canada. The federal government amended the Criminal Code in 2021 to permit single-game wagering, and each province now regulates its own legal betting market. Ontario launched its competitive, privately-operated online betting market in April 2022, and provinces like Alberta, British Columbia, and Quebec offer government-operated or provincially licensed options. Canadian bettors should always use licensed and regulated sportsbooks — both for legal protection and to ensure fair odds, secure payments, and access to responsible gambling tools. The decision to use only licensed operators is the most important one any Canadian bettor can make.

Question 4

What is the best odds format for Canadian bettors?

Accepted Answer

Decimal odds are generally considered the most beginner-friendly format and are the default display at virtually all Canadian sportsbooks. They make it easy to calculate your total return at a glance (Stake × Decimal Odds = Total Return) and to compare odds across different markets and events. The linear, straightforward nature of decimal odds — where a higher number always means a bigger potential return — makes them intuitive even for complete newcomers. Once you're comfortable with decimal odds, learning to read American odds is also valuable since many American-focused sites and odds comparison tools use that format. Ultimately, the "best" format is whichever one you find easiest to work with quickly — most platforms let you switch between formats freely via your account settings.

Question 5

Can I make consistent money from sports betting?

Accepted Answer

It is possible to generate consistent profit from sports betting over the long term, but it's extremely difficult and requires exceptional discipline, deep analytical skills, and a genuine edge over the bookmaker. Studies suggest that fewer than 5% of bettors are consistently profitable over multi-year timeframes. The most realistic approach for the vast majority of bettors is to view sports betting as a form of entertainment with a cost (like any other hobby), set a sensible budget, apply the strategies outlined in this guide to stretch that budget further, and celebrate winning sessions without expecting them every time. Your primary focus should always be on making well-researched decisions rather than chasing short-term profits. If you do have a genuine edge, applying disciplined bankroll management and line shopping will help you maximize it over time.

Question 6

How do I convert decimal odds to implied probability?

Accepted Answer

Converting decimal odds to implied probability is straightforward. Divide 1 by the decimal odds, then multiply by 100. For example, if a team is priced at 2.50, the implied probability is (1 ÷ 2.50) × 100 = 40%. This means the bookmaker believes there's roughly a 40% chance of that outcome occurring. If your own research and analysis suggests the true probability is higher — say 50% — then the bet represents positive expected value (value bet). The relationship between decimal odds and implied probability is linear and direct, making it easy to build a mental model for evaluating odds quickly. Over a large number of such bets, placing wagers where the true probability exceeds the implied probability is the foundation of a profitable long-term sports betting strategy.
