Sports betting is the entertainment industry’s oldest interactive product, and it has never been bigger or more televised. This section explains the machinery: what odds actually say, where the bookmaker’s margin hides, how the UK and Canadian markets are regulated, and how betting spread from the touchline to the red carpet.
Start With the Mechanics
Our guide to sports betting basics covers the vocabulary that matters: decimal against fractional odds, implied probability, the overround, and why a market that adds up to 105% means the book wins the argument before kick-off.
Know Your Market
Betting in Canada and the UK compares the two regimes this site’s readers ask about most: the UK’s mature licensed market and Canada’s rapid build-out since single-event betting became legal in 2021.
Beyond Sport
Entertainment betting looks at the markets this publication was always going to cover: the Oscars, the Grammys, reality television and the odd political special, and why novelty markets are priced so differently from a football match. Practical background lives in our earlier guide to picking a Canadian betting site.

Frequently Asked Questions
Is sports betting legal in Canada?
Yes. Single-event sports betting became legal federally in August 2021, and each province decides how to offer it. Ontario licenses private sportsbooks through iGaming Ontario; other provinces run their own platforms.
What is the difference between decimal and fractional odds?
Decimal odds state total return per unit staked, so 3.00 returns three units including your stake. Fractional odds state profit, so 2/1 wins two units for one staked. They describe identical probabilities in different dialects.
Why do bookmaker odds differ from true probabilities?
Bookmakers build a margin, the overround, into every market by pricing outcomes slightly shorter than fair. Summing the implied probabilities of a market above 100% reveals the margin you are paying.
