Some municipalities, such as Surrey, Richmond and North Vancouver have complete bans on fireworks, while Vancouver now requires anyone setting off fireworks to have a permit.
Vancouver Fire and Rescue spokesman Joe Foster says while the number of callouts was reduced, firefighters were still on the lookout for incidents.
"We've lowered the amount of damage being done out there probably due to some of the bylaw initiatives undertaken," said Foster.
"We've also sent our fire crews around every district around the city just to be a presence on the streets, just to hit those high target areas, the schools, the community centres, the parks"
Halloween also fell on a weekday, which may have kept some people at home, said Foster.
Police were called out to Granville Street around 3 a.m. PT after one man was knocked unconscious during an assault.
