The business of online gambling In Ontario: How the regulated market grew to C$3.2 billion

The iGaming market in Ontario has grown to become the largest regulated online gambling market in the country by a wide margin

FOUR YEARS AGO Ontario ran a straightforward bet: open its online gambling market to licensed private operators instead of running everything through a single government platform, and see what happened. The 2024-25 fiscal year answered that question in numbers few analysts expected this early. Ontario’s regulated iGaming market generated CA$3.2 billion in gross gaming revenue on CA$82.7 billion in total wagers, RealMoneyAction reported, both figures up roughly 30% from the year before, cementing Ontario as the largest regulated online gambling market in the country by a wide margin.

Where To Compare Licensed Operators

For anyone trying to make sense of how large Ontario’s iGaming market has actually become, a current breakdown of Canadian online casino operators licensed to serve Ontario players is a reasonable way to see the competitive landscape Ontario’s framework has actually produced, rather than relying on headline revenue figures alone.

From Single-Operator Monopoly To Competitive Marketplace

Before April 2022, Ontario residents who wanted to gamble online legally had one option: the province’s own lottery-run platform. Everything else operated in a grey market with no licensing requirement, no consumer protection standard and no tax revenue flowing back to the province. Ontario’s decision to open a competitive licensing framework, administered by a dedicated regulator working alongside the Alcohol and Gaming Commission of Ontario, changed that structure entirely. Private operators could now apply for a licence, compete for players directly, and build businesses around Ontario’s market specifically rather than serving it as an afterthought from an offshore platform.

What C$3.2 Billion In Revenue Actually Represents

That revenue figure isn’t just a headline for the operators collecting it. Ontario applies a tax on gaming revenue that flows into provincial coffers, and the sector now supports a meaningful base of employment across compliance, customer support, marketing and technical operations, jobs that didn’t exist in a licensed, taxed form in the province before 2022. The market’s growth rate is also worth pausing on: a 30% year-over-year increase in year three of operation is not the profile of a maturing industry settling into modest growth, it’s a market still expanding its player base and its share of what used to be grey-market activity.

The number of businesses involved has grown just as quickly as the revenue. Ontario’s market now counts dozens of licensed operators competing for the same player base, a structure that looks a lot more like a normal competitive industry than the single-provider setup most other Canadian provinces still run. That competitive pressure tends to push operators toward better product, faster payouts and clearer terms, the same dynamics that show up in any market once real competition replaces a monopoly, whether the product is online gambling or something as mundane as commercial insurance or accounting software.

Why This Matters Beyond Toronto

London and the rest of southwestern Ontario aren’t home to major gambling operators, but the broader lesson in Ontario’s iGaming build-out applies to plenty of local businesses navigating their own regulatory environments. A market that goes from single-operator monopoly to a competitive, well-regulated field of licensed businesses in four years is a fast timeline for any industry, and it offers a useful data point for anyone thinking about how quickly a regulated framework can attract serious capital and build real infrastructure once the rules are clear. That’s not so different from what this magazine tracks across the region’s own tech and services sectors, where clear rules and a level playing field tend to be exactly what lets smaller, well-run companies compete against bigger incumbents rather than getting squeezed out. Readers of our own coverage of the region’s growing business community will recognize that pattern, a well-defined operating environment is often the difference between a sector that consolidates around a handful of large players and one where a genuinely competitive field can take shape.

Where The Market Goes From Here

Ontario’s iGaming numbers haven’t slowed down since the 2024-25 fiscal year closed. Monthly figures reported through mid-2026 continued to show double-digit year-over-year growth, and Alberta became the second Canadian province to open its own competitive licensed market in July 2026, using a broadly similar structure. Whether Alberta’s early results end up looking anything like Ontario’s remains to be seen, but the underlying thesis, that a clear licensing framework can turn an already-large grey market into a taxed, regulated business sector fairly quickly, has now been tested twice in the same country within four years.
