Playing Castle of Terror for real money in Canada
Real-money online gambling in Canada is regulated province by province. Ontario runs a regulated market where licensed operators are overseen by iGaming Ontario and the AGCO; other provinces offer play through their own provincial sites, such as PlayNow (British Columbia, Manitoba and Saskatchewan), Loto-Québec, PlayAlberta and ALC in Atlantic Canada.
The legal age is 19 in most provinces and 18 in Alberta, Manitoba and Quebec. Only play at sites licensed where you live, set limits before you start, and treat gambling as entertainment, never as a way to make money.
