Vancouver police are stepping their enforcement for this summer’s Celebration of Light event, which kicks off tomorrow night in English Bay.
Chief Jim Chu says those carrying alcohol are likely to get questioned before, during and after the event.
"If the explanation does not make sense or if you're an underage drinker, then the police officers will take action depending on the circumstances."
The event is expected to attract four hundred thousand people from around the world.
The United Kingdom team shows off its fireworks skills tomorrow, while Canada presents on July 31 and Thailand on Aug 3.
