Hi pipo:
Gaming licenses are issued by the individual provinces, in Canada. For example, in Ontario, registrations are currently handled by the Alcohol and Gaming Commission of Ontario (
http://www.agco.on.ca/en/home/index.aspx). For other provinces, you will need to find the appropriate authority. Different provinces may have different requirements; however, as I understand it, most will require you to have confirmation of employment before a licence can be obtained. If you have a job lined up at an authorized establishment, they will typically have someone there who can assist you in the process.
