What Is Gambling?
Gambling is risking something of value, usually money, on an event with an uncertain outcome in the hope of winning more. Three elements define it: consideration (the stake), chance, and a prize. It spans lotteries, casino games, sports betting, bingo and poker. Commercial gambling works because payouts are set slightly below true odds, guaranteeing the operator a long-term margin.
The three ingredients: stake, chance, prize
Lawyers and regulators define gambling by three elements. You pay something to participate (consideration), the outcome depends wholly or partly on chance, and there is a prize to win. Remove any element and it stops being gambling: a free sweepstakes drops the stake, chess drops the chance, and a carnival game with no prize drops the reward. This three-part test is how courts decide whether a new product, from loot boxes to daily fantasy sports, counts as gambling.
Chance does not have to be total. Poker and sports betting involve genuine skill, but because chance materially affects each outcome, they are regulated as gambling in Canada. Pure chance games like lotteries and slots sit at one end of the spectrum; skill-heavy games where the house takes a fee, like poker, sit at the other.
How gambling works as a business
Every commercial gambling product pays winners less than true odds would dictate. Lotto 6/49 returns roughly half of ticket sales as prizes. A slot machine programmed at 95 percent RTP keeps C$5 of every C$100 cycled through it over time. A casino pays 35 to 1 on a roulette number that hits 1 time in 37. Individual results vary wildly, which is the product's appeal, but aggregate revenue is as predictable as a utility bill.
That margin funds everything else: the platforms, the jackpots, the marketing, and in Canada a large share of government revenue, since provinces conduct and manage most gambling. The practical takeaway for players is that gambling is entertainment with a built-in price, not an income strategy. The price per hour depends heavily on which game you choose and how fast you play it.
The gambling industry in Canada
Gambling in Canada is a provincially run industry worth well over C$15 billion a year in revenue, spanning provincial lotteries, about a hundred land-based casinos, charitable bingo and raffles, horse racing, and a fast-growing online sector. Crown corporations like OLG, BCLC, Loto-Québec and AGLC operate or oversee most of it, and profits flow into provincial budgets.
The online segment changed fastest. Ontario opened a regulated market for private operators in April 2022 under the Alcohol and Gaming Commission of Ontario and iGaming Ontario, and it now handles tens of billions of dollars in wagers annually, generating several billion in gaming revenue. Alberta passed legislation in 2025 to follow with its own open market. Globally, gambling is roughly a half-trillion-dollar industry, with online play the main growth engine.
