PROLINE+ review: is OLG's Ontario sportsbook worth using?

By Jeremy NadlerSenior reviewer, payouts Updated Nov 9, 2026

PROLINE+ is the online sportsbook of the Ontario Lottery and Gaming Corporation (OLG), and the only one in Ontario run by the province itself. This PROLINE+ review covers who can use it, what you can bet on, the published stake and payout limits, deposits and withdrawals, and how it stacks up against the private sportsbooks registered in Ontario's regulated market. We stick to what OLG and Ontario's regulators publish. Where OLG does not publish a number, such as its margin, we say so and show you how to check prices yourself.

What is PROLINE+?

OLG launched PROLINE+ on 27 August 2021, the day single-event sports betting became legal in Canada. Before that date, provincial lottery products could only sell parlays of two or more games. OLG built the platform with FDJ Gaming Solutions and Sporting Solutions, both part of France's FDJ Group, and at launch described it as offering pre-match and live bets across hockey, football, basketball, baseball, soccer, tennis, golf, boxing, MMA and motor racing.

PROLINE+ sits inside your OLG.ca account. If you already play OLG lottery or casino games online, you log in with the same account, and winnings are paid to that account balance. PROLINE+ itself has no horse racing, but OLG.ca has offered pari-mutuel race betting with Woodbine since August 2025; our guide to horse betting in Ontario covers it.

It is a separate product from PROLINE, the retail game sold at OLG lottery retailers. Retail PROLINE is open to players aged 18 and older, needs no account, and pays wins under $1,000 the same day, subject to the retailer. The retail limit is $100 per outcome, per player, per retail location, per day. PROLINE+ online is a different product with much higher limits, covered below. Alberta, Saskatchewan and Manitoba sell a different retail game with a similar name, WCLC's Sport Select PRO•LINE, covered in our Sport Select PROLINE guide.

Who can bet on PROLINE+?

OLG's player agreement sets three conditions:

You are 19 or older.
You live in Ontario.
You are physically in Ontario each time you play.

A resident of another province cannot open an account, and an Ontario resident on holiday in Quebec or Manitoba cannot bet until back in Ontario. For how the rules differ in each province, see our guide on whether sports betting is legal in Canada.

Bet types and features

PROLINE+ covers the standard menu for a modern sportsbook:

Singles and parlays. Single bets on one outcome, plus parlays that combine selections.
System bets. Round robins from 3 to 8 picks, including named bets such as the Trixie, Yankee and Goliath.
Same game parlays. You build your own, or take a pre-built same game parlay that PROLINE+ has assembled.
Live betting. In-play markets on the Live Betting tab, with odds that move throughout the game.
Cash out. A partial or early payout on selected events before the final result.
Early Payout. Special pre-match bets that settle as winners once your team reaches a set lead, whatever the final score. OLG says these are only on PROLINE+.
Pools. PROLINE POOLS, a pool-style game alongside the fixed-odds book.

The current PROLINE app adds live bet alerts, promo notifications and one-button withdrawals, and lets you build a slip for in-store play.

Limits: how much can you bet and win?

OLG publishes its wager limits, which many sportsbooks do not. On PROLINE+:

The absolute maximum on any one bet is $50,000, and some bets at that size may not be accepted.
Bets that would pay out more than $1,000,000 are not accepted. If your slip would exceed that, the stake is reduced automatically to a permitted amount.
Limits also depend on the event, current betting activity and liability.

The player agreement gives OLG the right to suspend or deactivate an account at its discretion. It does not publish a policy on limiting winning bettors, so we make no claim either way.

Odds and margin

OLG says PROLINE+ uses dynamic odds that update with game status and betting action. Neither OLG's site nor its rules publish a payout rate or average margin for PROLINE+, and we do not estimate one.

You can measure it yourself. Take both sides of a two-way market, convert each price to an implied probability with our odds converter, and add them. The amount above 100% is the book's overround. Our no-vig calculator does this in one step and shows the fair price. Repeat with the same market at a second regulated book, and you will see which one charges less for the same bet. Small gaps add up over a season, and parlays multiply the margin on every leg.

PROLINE+ vs Ontario's private sportsbooks

Ontario is the only province where the lottery corporation competes with a large regulated private market. iGaming Ontario (iGO) opened that market on 4 April 2022 with 13 operators live on day one. As of 1 September 2026, iGO lists 49 operators and 84 gaming websites.

Each private operator must be registered by the Alcohol and Gaming Commission of Ontario (AGCO) and sign an operating agreement with iGO. OLG.ca is different: it runs under OLG's own conduct and management and needs no iGO agreement. Both groups are regulated, both require players to be 19 or older, and both must check that you are in Ontario.

The practical differences, in general terms:

Choice of prices. With dozens of regulated books, an Ontario bettor can compare the same line across several sites without leaving the regulated system. PROLINE+ is one price among many.
Where the money goes. OLG says it reinvests all of its proceeds in provincial priorities. Private operators share gaming revenue with the province through iGO.
One account for OLG products. PROLINE+ shares your OLG.ca account with OLG's lottery and casino games and ties into retail PROLINE through the app.
Published limits. OLG states its $50,000 stake and $1,000,000 payout caps openly. Check each private book's own terms for theirs.

To confirm a private site is part of the regulated market, look for the iGO logo and check iGO's directory. Sites that are not listed are outside Ontario's regulated market, with no Ontario regulator to complain to.

Promotions

The promotions OLG lists in the PROLINE app are Second Chance bets and Profit Boosts, plus the return of PROLINE POOLS. Terms change, so read the conditions on OLG.ca before you opt in to anything.

Deposits and withdrawals

OLG.ca accepts Visa Debit, Visa credit, Mastercard, Debit Mastercard, American Express, Interac e-Transfer and Apple Pay. The player agreement sets a $15 minimum per deposit.

Withdrawals go by electronic funds transfer to your bank account. The minimum is $2, there is no maximum on a single withdrawal, and you can make one successful withdrawal request per day. OLG says verifying your bank details typically takes less than five business days, and players report funds arriving in one to five business days once approved. Crypto is not accepted.

Support and responsible gambling

OLG offers 24/7 live chat and a phone line at 1 855 978-7529, open 8 AM to midnight. PROLINE+ lets you set a sports spend limit, and OLG's PlaySmart program and My PlayBreak self-exclusion apply to your account. For help with gambling problems in Ontario, ConnexOntario is free and confidential at 1 866 531-2600.

Our verdict

PROLINE+ is a solid, fully regulated sportsbook with a modern feature set: live betting, cash out, same game parlays, system bets and Early Payout markets. Its published limits are clear and high enough for almost any recreational bettor, and the link with retail PROLINE and the OLG.ca account is convenient.

What it cannot be is the only book you check. OLG does not publish its margin, and Ontario bettors have dozens of regulated alternatives, so the sensible approach is to price your bet at PROLINE+ and at least one other registered book, then take the better number.
