Registered versus offshore sportsbooks: is the price really worse?
As of 2026-11-13 this site cannot say whether registered sportsbooks in Canada price worse than offshore ones. A fair comparison needs odds from both groups for the same event at the same moment, and we hold no odds snapshots. This page explains how to compute a margin yourself. Verdict: not verifiable by this site.

The claim
The claim, in its plain form, is that registered sportsbooks offer worse odds than offshore ones.
We have not collected statements of this kind from the reviews yet. When we do, each will be recorded with its URL, its date and a quote of 15 words or fewer.
A price claim can be true on one event and false on the next. For that reason a general statement about all registered or all offshore books is not something a table of a few events can prove.
Verdict: not verifiable by this site, because it holds no odds snapshots taken at the same moment.
What a fair comparison needs
- The same event, the same market, the same line (for example a total of 5.5).
- Prices from every sportsbook captured within the same minute.
- Many events across several sports and weeks, not a handful.
- Both sides of each market, so that a margin can be computed.
The project rule is that odds are not published as facts, so none of this is held here. The limit is stated on purpose: a page that claimed more would be inventing it.
AGCO Standard 1.21 is addressed to operators and concerns affiliates that promote sites without Ontario registration. Whether it applies to a site with no contract with an operator is a question for a lawyer, and it does not decide prices either way.
How to compute a margin
For a market with outcomes 1 and 2, convert each American price to an implied probability: negative A gives |A| / (|A| + 100); positive A gives 100 / (A + 100). Add them. The excess over 100% is the margin.
| Example (not an offer) | Price 1 | Price 2 | Implied probabilities | Sum | Margin |
|---|---|---|---|---|---|
| Market A | -115 | -105 | 53.49% and 51.22% | 104.71% | 4.71% |
| Market B | -130 | +110 | 56.52% and 47.62% | 104.14% | 4.14% |
| Market C | -105 | -105 | 51.22% and 51.22% | 102.44% | 2.44% |
If two sportsbooks showed markets B and C for the same event in the same minute, C would carry the smaller margin on that market.
The sums are done for you on the odds converter. The concepts are explained in vig and juice and implied probability.
Bottom line: one margin on one market is a data point, not a verdict about a group of sportsbooks.
What we could not check
- Prices at any sportsbook, registered or not.
- Whether taxes or rules alter prices: we found no source on this and publish nothing about it.
- Limits, withdrawal rules and safety tools, which a price does not show.
How to check this yourself
- Pick one event and one market that every sportsbook you use offers.
- Write down both prices from each, at the same minute.
- Compute each margin with the steps above.
- Repeat on other events on other days.
- Compare more than price. Registration in your province, deposit and withdrawal rules and responsible-gambling tools count too.

FAQ
Do registered sportsbooks in Canada offer worse odds than offshore ones?
We cannot say. A fair test needs prices from both groups for the same event at the same moment, and this project holds no odds snapshots. The claim is not verifiable by this site.
Why do you not list offshore sites to compare?
We do not recommend or link brands that are not registered in your province. A comparison that names them would promote them, so this page explains the method only.
How do I measure a sportsbook's margin?
Convert the price of every outcome of one market to implied probability, add the probabilities, and subtract 100%. A two-outcome market that sums to 104.14% has a margin of 4.14%.
Is a lower margin always better for the bettor?
A lower margin means a smaller built-in cost on that one market at that moment. It says nothing about limits, withdrawals, rules or safety, and margins change from event to event.
What does the Competition Act have to do with this?
A statement that one group of sportsbooks has worse odds is a factual claim about a product. The Act's rules on false or misleading representations, sections 52 and 74.01, apply to claims made to promote a product.
