Ontario's Crown sportsbook - and its old bad-odds reputation no longer fits
Visit PROLINE+ →PROLINE+ welcome bonus in Canada
Context for Canada: Canada regulates gambling province by province, so what is lawful depends on where you are. Ontario runs the country's open market: private operators register with the Alcohol and Gaming Commission of Ontario (AGCO) and operate under an agreement with iGaming Ontario, alongside the provincial operator OLG. Most other provinces keep online gambling with their own provincial operator. ONE ONTARIO RULE AFFECTS WHAT YOU SEE HERE: the Registrar's Standards for Internet Gaming prohibit advertising or marketing that communicates gambling inducements, bonuses or credits to the public - operators may still OFFER them, but may only advertise them on their own gaming site or by direct marketing to players who have actively consented. Permitted advertising must disclose material conditions up front, must not call an offer free unless it truly is, and must not call it risk-free where you stake your own money. If you are in Ontario, expect to find the current terms of any offer on the operator's own site rather than anywhere else, and treat a headline figure quoted elsewhere - including here - as something to verify at source.

Pros
- Owned by the Ontario government through OLG - an unusually accountable counterparty
- Regulated by the AGCO under an iGaming Ontario agreement, to the same standards as its private competitors
- Odds have genuinely improved: now rated competitive with the field, and better than average on big-four markets
- A sports offer alongside a casino match, with 14 days to use it
- 10x wagering on the casino side is moderate by market standards
Cons
- Its historic reputation for poor odds still colours perceptions, and one reviewer maintains odds are not its strongest suit
- Ontario prohibits public advertising of bonuses, so any figure quoted off-site - ours included - needs verifying at source
- Ontario only; other provinces generally route online gambling through their own provincial operator
- No independent measurement of payout speed found
- The casino side carries a wagering requirement where the sports offer does not
Our verdict
PROLINE+ is a straightforwardly good option for an Ontario bettor, and the interesting part of this review is that its bad reputation no longer fits. The old retail Proline priced poorly because it could - it was the only lawful sports bet in the province. Competition changed that, and Ontario reviewers now rate PROLINE+ odds as competitive with the rest of the iGaming Ontario field, several of them better than average on the main big-four markets. We say so directly because we have marked other monopolies down on this site for the absence of exactly that pressure; here it arrived and the operator responded. Behind it sits the Ontario Lottery and Gaming Corporation, a provincial Crown operator regulated by the AGCO under an iGaming Ontario agreement and held to the same standards as its private rivals. One practical note: Ontario prohibits advertising bonuses and inducements to the public, so whatever offer figure you see quoted off-site - including ours - should be checked on OLG's own site before you act on it.
How we rated it
Sportsbook & odds (40%)8
Raised on the evidence. PROLINE+ odds are now rated competitive with the wider iGaming Ontario field, and better than average on main markets for the big four leagues - a genuine change from the retail Proline product's poor reputation. Not unanimous: one reviewer still calls odds not its strongest suit.
Payments & payouts (20%)8
A provincial Crown corporation is about as accountable a counterparty as exists in this industry, operating under AGCO regulation. We found no independent measurement of payout speed.
Trust & licensing (20%)8
Owned by the Ontario government through OLG and regulated by the AGCO under an iGaming Ontario agreement - notably, held to the same standards as the private operators it competes with, rather than regulating itself.
Bonuses & value (20%)7
A bet $25 get $100 sports offer with a casino match alongside, 14 days to use it and 10x wagering on the casino side. Verify it on OLG's own site: Ontario's rules prohibit advertising inducements publicly, so a figure quoted anywhere else, here included, may not be current.

About PROLINE+
PROLINE, and its online sportsbook PROLINE+, is run by the Ontario Lottery and Gaming Corporation - the province's Crown gambling operator - and is regulated by the Alcohol and Gaming Commission of Ontario under an agreement with iGaming Ontario. That last point is worth dwelling on: OLG does not regulate itself. It operates inside the same framework as the private sportsbooks that entered Ontario when the province opened its market, and is held to the same Registrar's Standards. The most useful thing we can tell you is that PROLINE's reputation is out of date. The old retail Proline product was widely criticised for poor odds, which it could afford to be while it was the only lawful way to bet on sport in Ontario. Since competition arrived, that has changed: Ontario reviewers now rate PROLINE+ odds as competitive with the rest of the iGaming Ontario field, and several rate them better than average on the main markets for the big four leagues. We think that deserves saying plainly, because elsewhere on this site we have marked monopolies down precisely for lacking competitive pressure - here is a case where that pressure arrived and the operator responded. The picture is not unanimous, and one reviewer we read still describes odds as not the sportsbook's greatest strength while accepting they stand up against comparable books. One caution about offers. Ontario's Registrar's Standards prohibit advertising gambling inducements, bonuses or credits to the public. Operators may still offer them - they may only advertise them on their own gaming site, or by direct marketing to players who have actively consented. So treat the bonus figure we hold as a pointer, and confirm the live terms on OLG's own site.
PROLINE+ FAQ
Is PROLINE legitimate?
It is run by the Ontario Lottery and Gaming Corporation, the province's Crown gambling operator, and regulated by the Alcohol and Gaming Commission of Ontario under an agreement with iGaming Ontario. It is about as accountable as an operator gets - and notably, it is held to the same Registrar's Standards as the private sportsbooks it competes with rather than setting its own.
Are PROLINE's odds still bad?
That reputation is out of date. Retail Proline earned it when it was the only lawful sports betting option in Ontario and had no reason to price sharply. Since the province opened to competition, reviewers rate PROLINE+ odds as competitive with the wider iGaming Ontario field, with several rating them better than average on main markets for the big four leagues. One reviewer still disagrees, calling odds not its greatest strength while accepting they hold up.
Why do you tell me to check the bonus on OLG's own site?
Because Ontario's Registrar's Standards for Internet Gaming prohibit advertising inducements, bonuses or credits to the public. Operators can still offer them, but may only advertise them on their own gaming site or by direct marketing to players who have actively consented. A figure carried on a third-party site, including this one, is therefore something to verify at source rather than rely on.
Can I use PROLINE outside Ontario?
Canada regulates gambling province by province. Ontario runs the open, AGCO-regulated market; most other provinces keep online gambling with their own provincial operator. PROLINE is Ontario's.
Why did your rating change?
It was 8.2 from a single affiliate bonus page. Proper research raised the sportsbook score, because the evidence on odds is better than PROLINE's reputation suggests, and added the Ontario advertising rules that affect how you should read any bonus figure. Overall moves slightly to 7.8, with the components now individually sourced rather than assumed.
