TonyBet Review
When it comes to the sports betting experience, there’s plenty sorely lacking here. From the vig-heavy odds to the strangely complicated interface to the list of sports with a more European audience in mind, it stands to wonder whether TonyBet truly cares about its Canadian audience.

Features
- Massive selection of markets.
- Easy-to-use interface.
- Wide variety of deposit/withdrawal options.
Betway Review
While this book won’t wow you with its design, you won’t find many apps easier to navigate – or with the sheer volume of sports markets Betway offers. Combine that with one of the best esports betting experiences in the province, and you have a global sports betting brand that deserves to be mentioned among the top options in Ontario.

bet365 Review

Features
- Strong offering of sports markets.
- New look and mobile app now in Ontario
- Easy deposits and withdrawals.
Sports Interaction Review
SIA could be positioned to make a dent in the massive Ontario sports betting market. But while the product stands up well, the lack of a mobile app and a mediocre props market, among other things, will make it difficult for Sports Interaction to keep up with the lead pack.

- New Bet Tracker feature for great NBA experience.
- 150+ live markets and competitive odds.
- Early cash-outs and seamless deposit options.
PointsBet Review
PointsBet easily offers one of the best and most unique products in a copy-cat market. As long as you can stay off their radar as a sharp bettor, you will be hard-pressed to find a better product.
Features
Great Selection of Player Props
Terms and conditions apply.
BetVictor Review
BetVictor deserves significant credit for remaining relevant three-quarters of a century after first launching its bookmaking product. But its no-frills approach to the Ontario sports betting market is going to be a difficult sell compared with operators who do much more for their customers.

BetMGM Review
The sports betting platform at BetMGM is easily one of the most popular in the online sports betting market.

DraftKings Review
DraftKings has a decent reputation among the sports betting community, especially for beginner bettors. It already had a loyal base of DFS customers, so the shift to legal sports betting was natural. However, if you’re a sharp bettor, high-limits bettor, or even lucky enough to go on a tear, you will not be very welcomed.

How March Madness betting promos work
March Madness is one of the biggest betting events of the year for most sportsbooks. Nearly $3 billion was bet on the 2024 NCAA Tournament.
It's very popular with the brackets that users fill out as well, but sportsbooks have plenty of odds and boosts to choose from, making it super popular over the duration of the tournament.
Generally, here's how March Madness betting promos work:
1. Choose a sportsbook
Pick a sportsbook from our toplist above the page, or find another good option that is legal and licensed in your location/state. It may be advantageous for you to register someplace with the best promo because the greatest benefits are typically only available to new users. At the moment, bettors can use the Fanatics Sportbooks promo code for a $1,000 welcome offer. Additionally, the majority of sportsbooks also provide good March Madness promotions for current customers. You'll find that the top-rated NBA betting sites are often with the best promotions, too.
2. Make a deposit
Depositing into your sportsbook account for the first time is necessary to claim the bonus. Almost every promotion will require you to make a minimum deposit and a small real money wager of some kind. Most sportsbooks have a minimum deposit of $5 or $10 (depending on the banking method). Finding a deposit minimum lower than $5 is rare these days.
3. Use a promo code
Not every March Madness betting bonus offer requires a promo code, but some do. Refer to our table of verified and exclusive promo codes above, but SBRBONUS is required for BetMGM and bet365, and SBRBONUSDYW for Caesars. If needed, make sure you input the code when you register or deposit to claim the best possible bonus.
4. Place your bet
The March Madness tournament has almost endless betting options. You can simply pick a team to win on the moneyline or point spread or go with something more exotic like a game or player prop bet. March Madness, which will surely see exciting finishes and buzzer-beaters, have novelty props that keep the excitement going for weeks. You can also bet on the futures market, so pick the winner of the tournament instead of a moneyline.
5. Collect the bonus
Whether you opted for a 'Bet & Get' offer, a 'First-Bet Insurance' deal, or something slightly different, it's now time to collect your March Madness bonus. Ensure you've met all the terms and conditions first. Most bonuses will appear in your account instantly if you meet the criteria required.
6. Cash out
Hopefully, your March Madness bet was a winner, and you now have some profit to withdraw. Or you earned some bonus bets that will give you another chance to make a winning bet. Maybe even both!
Head to your sportsbooks' Banking or Cashier section, and follow the steps to ensure you get the withdrawal options on your side.
