Three sources, and each figure on the money page is labelled with which one it came from.
The operator's own page. Loaded from a Canadian context — Canadian locale, Canadian timezone, English-Canadian language headers — because several operators show a different currency and a different offer until they detect where you are. A figure labelled this way was read off the operator's own site.
Our Canadian brand catalogue. A per-geo bonus catalogue maintained by the team. It is accurate most of the time and it is not infallible: on this build it carried one brand's European tier on a Canadian page, which the operator's own site corrected.
Not published. The honest third option, used where neither source could confirm a figure for Canada.
No withdrawal time in hours. It varies by rail, by amount, by whether the account was already verified, by the day of the week and by how the operator staffs its review queue. A single number per brand would be a fiction, and the pages that print one are printing a fiction too.
What this site does instead is name the three clocks a withdrawal passes through, say which of them the casino actually controls, and print whatever processing windows the operator publishes for itself. On this build exactly one operator published windows clearly enough to quote.
The order of the list is commercial and follows our Canadian lineup, not a payout-speed ranking. Where a brand's position and its published terms disagree, the terms are printed next to it so the disagreement is visible rather than hidden.
