Short answer — there are only a few regulated Canadian gambling sites that work with PayPal, and many international sportsbooks/casinos that advertise PayPal accept it only in certain provinces or for certain products. The safest options for Canadians who want to use PayPal are:

Recommended PayPal-friendly options (Canada)

• PlayNow (BC / MB / SK) — provincially regulated site that supports PayPal for deposits (availability depends on province). (casino.org)
• PlayAlberta / ALC.ca (Alberta / Atlantic provinces) — provincial platforms where PayPal is supported on some products or during integrations. (casino.org)
• Caesars (Ontario iGaming offerings) — large, regulated Ontario operator that lists PayPal as a supported payment option for deposits and (in some cases) withdrawals. Availability is limited to Ontario players on provincially licensed sites. (casinoofthekings.ca)
• Selected internationally licensed sportsbooks/casinos (e.g., PlayOJO, LeoVegas, Rizk, Spin) — these well-known brands often support PayPal for Canadian customers, but use is frequently restricted by province and site licensing (you may need to be in a province where the site is allowed to operate or use a region-specific site). Always confirm on the operator’s payments page before registering. (Gambtopia.com)

Important context and tips

• Provincial/regulatory limits: PayPal relationships with gambling sites in Canada are constrained by provincial regulation — most PayPal casino/sports options are available only on provincially regulated platforms (Ontario, BC, Alberta, etc.) or within specific Indigenous territories that host licensed operations. Do not assume every site that lists PayPal will let you both deposit and withdraw via PayPal from your location. (casino.org)
• Deposit vs withdrawal: Even when PayPal deposits are accepted, withdrawals back to PayPal are not guaranteed. Many operators require alternative withdrawal methods (bank transfer, Interac e-Transfer) unless you funded with PayPal and meet conditions. Check the specific operator’s banking/withdrawal terms. (casinoofthekings.ca)
• How to verify: Before you sign up or deposit, open the site’s Payment / Banking section and confirm “PayPal” is listed for deposits and withdrawals for your province (and whether any KYC/hold periods apply). Also confirm the operator’s licensing (AGCO/iGO for Ontario, AGCO/BC for BC, etc.). (casino.org)
• Safety & fairness: Prefer provincially licensed sites or major international brands with licences from recognized regulators (e.g., iGO/AGCO, UKGC, MGA) and clear responsible‑gaming tools. PayPal availability is a convenience, but licensing and payout reputation are higher‑priority safety signals. (casino.org)

If you want, I can:

• Look up PayPal availability for a specific province (e.g., Ontario, BC, Alberta) and list currently confirmed PayPal-accepting sportsbooks/casinos for that province (I’ll check each site’s payments page and link sources).
