The running order is commercial. These are the operators this site holds affiliate arrangements with, in the order those arrangements set. Saying that plainly is more useful than presenting a paid order as the result of a test.
What is not commercial is everything beside the names. Welcome offers are quoted in each operator's own wording and in the currency that operator publishes them in. Where a figure could not be confirmed against the operator's own terms, the page uses the most consistent value across the live comparison pages carrying the same operator list — and where those disagreed, the lower figure, because overstating a bonus is the error that costs a reader something.
Two operators publish in euros. Tenobet and Zizobet advertise their welcome offers in euros to Canadian-facing traffic and publish no Canadian-dollar figure. Those rows keep the euros. Several comparison sites print a Canadian-dollar number for both; that is a conversion of a figure the operator has never advertised, and the rate you actually get is the cashier's.
No scores. Nothing on this site carries a rating, a grade or a number out of ten. A score implies a precision this kind of comparison cannot support, and it lets a reader skip the clauses that decide what an offer is worth — the wagering multiple, what it applies to, the maximum cashout, and whether the payment method works in both directions.
Provincial availability is checked first. Two of the fifteen hold an iGaming Ontario registration; the other thirteen do not. A ranking that shows the same list to a reader in Toronto and a reader in Halifax is telling one of them something untrue by omission, so the provincial position is stated on the money page above the bonus arithmetic.
Corrections. Offers change constantly. If something here does not match what the operator publishes, send the page and what you are seeing and it will be corrected.
