Short answer is yes. They are basically licensed most commonly under the carribean island of Cuaracao which gives easy licenses on online gambling casinos . The license is usually located below their website and is near a badge. With a licensed gambling site they can literally and legally offer their casino to every country who isn't prohibiting foreign licensed casinos. Also some gamblings casinos are locking ip addresses of countries that don't allow their services they are prohibiting players from that country to play so you don't have to worry if you are a canadian or amserican as chances are you can't even create an account in their website if your country is prohibited.
