Short answer: Many Canadian online casinos accept e‑transfer via Interac (often processed through services like Gigadat). Examples of well-known sites that list Interac/e‑Transfer as a payment option include CasinoDays, Jackpot City, PlayOJO, TonyBet, Mr.Bet, MyStake, Qbet, Dolly Casino, NeedForSpin and NineCasino.

Quick details and tips

• What “e‑transfer” means here: most Canadian casinos use Interac e‑Transfer (or Interac Online) for deposits and many also support Interac e‑Transfer withdrawals. You may see payments on your statement as “Interac” or the payment processor name (e.g., Gigadat). (Gambling.com)
• Deposit speed and limits: Interac deposits are normally instant; minimums commonly range C$5–C$25 depending on the site, and withdrawal speeds vary (same day to a few business days). Fees are usually low or absorbed by the casino but Interac can charge small per‑transfer fees. (time2play.com)
• Provincial rules: availability and allowed payment options (and licensing) can differ by province (Ontario has its own regulated market iGaming Ontario). Always check the cashier page of the casino and that the site accepts players from your province. (time2play.com)

How to confirm for a specific site (fast checklist)

1. Open the casino’s Cashier/Banking page and look for “Interac”, “Interac e‑Transfer”, “Interac Online” or “Gigadat.”
2. Check minimum deposit, withdrawal limits and processing times.
3. Verify licensing and whether the casino accepts players from your province.
4. Read the casino’s withdrawal/verification requirements — Interac withdrawals typically require account verification. (Gambling.com)
