Depositing more to feel the same thing. Chasing a loss with a bigger deposit. Cancelling a withdrawal to keep playing — which is the one this site writes about most, because the reverse window is designed to invite it. Borrowing or moving money earmarked for something else. Hiding how much you play. Any one of those alone is a reason to stop and take stock.
Set a deposit limit before you play rather than after. Every operator here offers deposit limits, session reminders, cooling-off periods and self-exclusion in the account settings, and they are easy to miss. Device-level blocking such as Gamban or BetBlocker covers everything at once and cannot be undone in a bad moment.
This matters and is rarely said. Self-exclusion at an offshore casino covers that operator only. Ontario's licensed market has a central self-exclusion register that works across every registered site; the offshore operators on this page have nothing equivalent. If you need to stop, device-level blocking is far more reliable than trusting fifteen separate account settings.
You do not need the person's permission to get help yourself. ConnexOntario takes calls from relatives as readily as from players, and Gam-Anon runs groups for families across the country.
