For many years, online gambling has occupied a rather grey area in terms of government regulation in Canada. Although there are offshore casino sites that offer their services to Canadian players, it can be hard to tell if they are reputable, safe slot sites with a focus on responsible gambling.

With one of the biggest online gaming markets in Canada, Ontario is regulating the online casino sector, which is great news for fans of real money slots. A proper legal framework acts as quality control in the online gaming industry in the region and means that Ontario players will have access to the best slot sites once the regulation process is completed.

We will update this section with the best online casinos Ontario players can visit when the licenses are awarded.

There are more than 70 land-based casinos scattered across the province, with more than 30,000 slot machines and hundreds of table games on offer. Ontario residents can also bet on horse racing and play lottery games.

Ontario has one of the most robust gambling markets in the country, and with the new regulation framework, slots fans can explore a much wider variety of top-quality slot games, the best progressive jackpot slots, live casino games with real dealers, and a variety of other casino games including classics like blackjack and roulette.

Playing online brings slot players thousands more gaming options than any land-based facility. As well as the sheer variety of slots available, online slot sites offer convenience, quick registration, and several secure payment options to allow players to get started in minutes.

As the regulation of the gambling industry progresses, slot players in Ontario will have access to a much wider range of regulated, reputable online slot sites. Instead of a limited selection of offshore casino sites, slots players will be able to explore new slot sites as well as established casino brands with years of experience in the slots entertainment industry.

This table explains the changes that players in the province can expect now that legal online gambling in Ontario online casinos is imminent:

You must be aged 19 or older to sign up for an account with one of the province's real money slot sites. Ontario players will be asked to upload a scan of their official photo ID, such as a passport, during the sign-up process to prove their age.

We will sign up for accounts with the various licensed online casinos in Ontario, make deposits, play a wide array of games, and request payouts. During this process, we will assess the game quality, game variety, RTP ratios, banking options, user experience, mobile app, customer service, promo terms, and security measures available at each site. We can then compare them against one another and identify the top slots in Ontario sites for our readers. We review any new slot sites in Ontario that launch and check up on existing sites to ensure they continue to uphold high standards.

The best Ontario slot sites will stand out from the crowd by offering an exciting gaming experience, attractive bonuses, and rapid payouts. They must also provide a strong selection of the best slot games, from old-school 3-reel games to the latest 3D slots, branded slots, first-person slots, and progressive jackpot games. The top slots in Ontario will include classics like Cleopatra, Gonzo's Quest, and Starburst, along with popular games such as Mega Moolah and Immortal Romance.

The best slot sites will offer slot games from a variety of software providers. You could play the top NetEnt slots, some of the best Microgaming slots, and explore the quirky themes of the most popular Play'n GO slots, all at a single online casino site. You should also find unique games from boutique studios.

The best online casinos in Ontario will also feature a wealth of virtual table games and live dealer games. You can play blackjack, roulette, baccarat, video poker, Hold'em, craps, and game show titles, with broad betting limits and sharp graphics.

Canadian sports fans have always been able to place parlays, but they had to turn to offshore books if they wanted to enjoy single-game sports wagering. That all changed with the passage of the Safe & Regulated Sports Act in 2021. Leading sportsbook brands in the US and Europe are now gearing up to launch in Ontario, along with local operators, so there will be a vibrant legal sports betting industry for bettors in the province to use.

You will be able to play a wide array of online slots on any iOS or Android device when you sign up for an account with one of the top online casinos in Ontario. Some of the top slot sites offer slot apps, which can be downloaded via Google Play, the App Store, or direct from the site. All of the best Ontario casino sites should have a mobile-optimized version of the site. The latest slot games are all mobile-ready, allowing you to play them in the palm of your hand. We will highlight the best mobile slots in Ontario for our readers.

Top Ontario slot sites must offer a selection of the top payment methods to play real money slots in Canada. Deposits and withdrawals should be smooth, quick, safe, and convenient. We may see them start to offer popular PayPal slots, Skrill slots, and Neteller slots, which have been notably absent at some sites that operated under the previous "grey area" in legislation. These are some of the payment options we expect to see at the best Ontario slot sites:
 

Offshore online casinos will continue to target players in Ontario during this brave new era of legalized online gambling. In a market where money is at stake, it is always wise to be wary of rogue operators. Once the regulation has passed, we will vet the online slot sites that offer their services in Ontario, and list the ones that continue to operate without licenses, and any other dodgy operators in this section. This will be your go-to guide for the blacklisted casinos that you should avoid.

Online slot games are intended for entertainment purposes, but if your gaming crosses the line from fun to problematic, then reputable online casinos should have Responsible Gambling guidelines and processes in place. Online slot sites that are regulated in Ontario should offer several safeguards to protect their players, including varying self-exclusion offers.

The online casinos in Ontario will take responsible gambling very seriously. You should be able to access a dedicated page within the site that explains its commitment to stamping out problem gambling, protecting minors, and upholding high standards in terms of fairness. You should be able to impose limits upon your account, such as time limits, deposit limits, and loss limits, or take a time-out or self-exclude.

The best Ontario slot sites will provide advice on how to gamble responsibly and how to spot signs of problem gambling. You may find a questionnaire or a list of myths associated with gambling. You should also be presented with links to external charities and agencies that can help, such as the Ontario Problem Gambling Helpline.
