What is a parlay bet?

A parlay combines two or more bets into one ticket. Every leg must win; if one loses, the whole ticket loses. In return the odds multiply, so a few modest prices become one long one.

Which Ontario sportsbook pays the most on parlays?

It depends on the legs. On 29 October 2026 the four NHL favourites, the Hurricanes, the Mammoth, the Lightning and the Senators, paid +575 at Pinnacle, +571 at NorthStar Bets and +491 at Swiper. On the four underdogs, the Blue Jackets, the Penguins, the Jets and the Kings, Pinnacle paid the most again, +4145, while Betway, third on the favourites, was last of 12. Build the same ticket at two or three books before placing it.

What happens if one leg of a parlay pushes?

At most books the pushed leg is removed and the parlay is repriced with one leg fewer. Same-game parlays and postponed games can follow different rules, so check your book's terms.

How many legs should a parlay have?

Fewer is cheaper. Each leg adds the book's margin again, and the chance of every leg winning falls quickly: with coin-flip legs, about 25% for two legs, 6% for four and 0.4% for eight.

Are parlays legal in Ontario?

Yes, at every sportsbook on the iGaming Ontario register, including same-game parlays. You must be 19 or older and physically in Ontario.

A parlay bet joins several bets into one ticket: every leg has to win, and the odds – and the book’s margin – multiply. On 29 October 2026 the same four-leg NHL parlay offered $67.50 on $10 at the best of 12 Ontario books and $59.07 at the worst.

That multiplication is the whole appeal – and the whole catch.

What Is a Parlay?

A parlay – called an accumulator or multi in other countries – combines two or more selections into a single bet. If every selection, or leg, wins, the parlay pays the product of their odds. If any leg loses, the whole ticket loses.

Small stakes, big returns. Four NHL favourites and one NFL favourite at NorthStar Bets would pay $107.97 on a $10 stake.
Any market can be a leg at most books – moneylines, spreads, totals, props – and legs can come from different sports.
One loss sinks the ticket. There is no partial payout for three winners out of four.
The margin compounds. A 4.8% margin per leg – the standard -110 on both sides – means the book keeps about 17% of a four-leg parlay of -110 bets.

How Parlay Odds Are Calculated

Convert each leg to decimal odds, multiply them, and multiply the result by your stake. Here are the four NHL favourites at NorthStar Bets on 29 October:

Leg	American	Decimal
Hurricanes to beat the Blue Jackets	-265	1.38
Mammoth to beat the Penguins	-130	1.77
Lightning to beat the Jets	-235	1.43
Senators to beat the Kings	-109	1.92
Four-leg parlay	+571	6.7064

A $10 parlay returns $67.06: $10 x
