Are you a high-stakes player looking for a bonus that’s actually worth your while? If so, you’ve come to the right place. I’ve reviewed all the best legal online casinos in Ontario. Below, I’ll break down the best Ontario online casino bonuses and promotions for high-stakes players along with some other features that make these casinos good options for high-rollers like you.
5. Casino Days
Casino Days is a fun online casino with a unique daily promos feature that I covered in our top five high-roller Ontario online casinos list. It makes this shortlist, though, purely for its welcome bonus. Casino Days will match 100% of your first deposit up to $2,000 and will give you up 100 bonus spins for the Sweet Bonanza online slot.
I like this offer because it’s simple — you don’t need to make multiple deposits — and also because the maximum value is far higher than other bonuses on the market. However, it has a 35x wagering requirement and some other terms that make it less worthwhile than some smaller bonuses.
Here’s an overview of the Casino Days bonus wagering requirement and other important terms and conditions.
- Minimum Deposit: $20
- Offer Expiry Period: 30 days
- Wagering Requirements: 35x
- Wagering Period: You have 30 days to fulfil the wagering requirements.
- Game Contribution: Slots – 100%; Table games, live dealer games – 10%; Video poker and all other games – 0%.
- Maximum Bet: $10
- Maximum Win: $30
4. ToonieBet
Founded in 2024, ToonieBet is one of the newest online casinos in Ontario. Unlike so many other new betting sites, ToonieBet is actually a Canadian company. It’s based in Toronto, and earns the No. 4 spot on our list thanks to its generous $1,800 welcome bonus.
The ToonieBet bonus is actually a four-part welcome package worth a maximum value of $1,800. Here’s how this offer breaks down:
- First Deposit: 100% Deposit Match up to $500 + 200 Free Spins
- Second Deposit: 75% Deposit Match up to $500
- Third Deposit: 50% Deposit Match up to $500
- Fourth Deposit: 100% Deposit Match up to $300
Another thing I like about this offer is how simple it is. It’s not a back-loaded package that requires huge upfront deposits for nothing before you actually get any rewards. As you can see above, all four parts of the ToonieBet bonus are simple deposit match offers. The first deposit bonus is even better than the last.
Despite being so simple, like all bonuses, the ToonieBet offer has some important terms and conditions that you need to know about. See below:
- Minimum Deposit: $30
- Offer Expiry Period: N/A
- Wagering Requirements: 20x (30x for free spins)
- Wagering Period: Wagering requirements must be completed within 10 days
- Game Contribution: Slots – 100%; All other games – 10%; Bingo – 0%
- Maximum Bet: $8
- Maximum Win: N/A
3. TonyBet
TonyBet is a British betting site that jumped across the pond and secured an iGaming Ontario license in 2022. It’s mostly known for its sports betting. However, you can also enjoy hundreds of games from world-class software providers, like Pragmatic Play and Hacksaw Gaming.
Other sites have more games, but the high-value welcome offer makes TonyBet hard to overlook on a list of the best online casino promotions for high-stakes players. TonyBet will give you up to $2,500 in bonus bets across your first four deposits, plus 225 free spins for select online slots.
Here’s a full explanation of the entire TonyBet welcome package:
- First Deposit: 100% deposit match up to $1,000 + bonus spins on Mummy’s Jewels according to your deposit amount.
- Second Deposit: 125% deposit match up to $500 + bonus spins on The Dog House according to your deposit amount.
- Third Deposit: 50% deposit match up to $500 + bonus spins on Chilli Heat Spicy according to your deposit amount.
- Fourth Deposit: 25% deposit match up to $500 + bonus spins on Book of the Fallen according to your deposit amount
In addition to the basic bonus terms above, here are the other TonyBet welcome offer terms and conditions you should familiarise yourself with:
- Minimum Deposit: $20
- Offer Expiry Period: 14 days
- Wagering Requirements: 30x
- Wagering Period: Bonus credits expire 14 days after being added to your account.
- Game Contribution: Slots – 100%; All other games – 0%.
- Maximum Bet: N/A
- Maximum Win: N/A
Sports Interaction is a household name here in Canada, with history dating back to 1997. In my opinion, it’s done a better job keeping with foreign competition than pretty much any other Canadian betting site. One of the big reasons Sports Interaction has excelled is its bonus offers.
If you sign up now, Sports Interaction will match 100% of your first deposit up to $3,000 — that’s six times more than the standard bonus offer available in Ontario. The only thing this offer’s missing are free spins. Overall though, it’s hard to argue with the high bonus amount and value for money.
The Sports Interaction welcome bonus has a 30x wagering requirement. Here’s a deeper dive into that requirement and the other bonus terms and conditions:
- Minimum Deposit: $10
- Offer Expiry Period: Deposit must be made within the first 10 days after opening your account.
- Wagering Requirements: 30x
- Wagering Period: You have 14 days following your qualifying deposit to complete the bonus wagering requirement.
- Game Contribution: Slots and Jackpot Slots – 100%; Live dealer roulette, crash, and mines – 20%; Live dealer blackjack and blackjack – 10%; All other games – 0%.
- Maximum Bet: N/A
- Maximum Win: N/A
I tried to avoid just picking the five biggest casino bonuses in Ontario because, despite what people say, bigger is not always better. However, in this case, BetMGM Casino Ontario has the biggest bonus offer and it happens to be the best for high-stakes players.
New players can claim a simple 100% deposit match bonus to earn up to $3,000 in bonus credits. To make it even better, BetMGM will also throw in another $100 when you complete your first deposit. This gives the BetMGM bonus a $3,100 maximum value, just narrowly edging out Sports Interaction.
Before you rush to sign up for BetMGM Casino Ontario, make sure you look over the BetMGM welcome bonus terms and conditions below:
- Minimum Deposit: $10
- Offer Expiry Period: Deposit match is available for 30 days after you create your account. $100 Casino Bonus is available for three days.
- Wagering Requirements: 15x (10x for $100 casino bonus)
- Wagering Period: Wagering requirements must be completed within 14 days
- Game Contribution: Slots – 100%; Table Games (except blackjack) – 20%; Live Dealer Games – 20%; Blackjack – 10%.
- Maximum Bet: N/A
- Maximum Win: N/A
