More than 400,000 people are expected to attend this year's festival, billed as one of the best fireworks shows in North America.
The British team is one of three countries competing in the 23rd edition of the summer light show. They will be followed by Canada on July 31 and Thailand on Aug. 3.
Organizers say there is more than $100,000 worth of fireworks on the big black barge moored off English Bay Beach for each team.
This year's Red Bull airshow will coincide with Canada's fireworks on Aug 3. Another performance is scheduled for July 31. Both airshows kick off at 8:10 p.m.
