Lots of casinos in the area. There's Parq casino directly downtown Vancouver, but there's pretty much 1 casino per major city in the area. Grand Villa in Burnaby, Great Canadian in Coquitlam, River Rock in Richmond, Cascades in Langley, Starlight in New Westminster and Cascades in Delta. Nothing in West or North Vancouver.
Do lots of research about cost of living. It's quite expensive here. Renting is sky high, and owning is even higher. There's very high tax rates in BC & Canada as well so take that into account. Public health has it's advantages, and disadvantages but at least you're covered. Transit in Vancouver and the very nearby areas is quite decent, but anywhere in the suburbs turns quite poor.
It's a beautiful city to live in, and in the surrounding cities and suburbs. It rains a lot, but that also gives our area lush greenery all year round. Several local mountains to ski, snowboard and show shoe in the winter, then mountain bike, hike or walk in the summer. Then less than an hour away there's lots of beaches and plenty of hiking trails anywhere you look.
The food is amazing. Lots of events all the time like Christmas markets, conventions, and a pretty good poker community. Lots of PCF'ers.
What role in the casino are you looking to get into? Dealer? Manager?
@Racer96 can give you lots of insight as a former dealer and supervisor at Grand Villa for several years.
