What to include in a correction
Give the page address, the sentence or row you think is wrong and what you believe is right. A link to the regulator's own page is the strongest evidence, because a row changes only when its list shows something different. A company that finds its own entry out of date can write the same way. Entries are never changed or removed for payment.
What the site cannot do
The site does not hold money, so it cannot reverse a deposit or settle a dispute with a casino. The regulator named on the page for your province is the next step after the operator itself. Questions about tax or about the law as it applies to one person need a lawyer or an accountant.
Contact for press and research
Journalists and researchers can write to the same address about how a page was put together. Answers come from the sources listed on the page in question.
