The fire broke out at 3 p.m. PT Tuesday just above the Horseshoe Bay Ferry Terminal. It flared up again on the steep slope early Wednesday morning.
Assistant Chief Jeff Bush said the fire was the 11th in recent days on the North Shore of Vancouver, and almost all of them were started by humans.
It appears this fire was also caused by a careless person as well, said Bush.
"There's no structures. There's no trails. There's no way of accessing it from below. So my guess is it's another tossed cigarette," he said.
As long as the dry weather continues, people need to be more cautious, he warned, because of the increased forest fires could spread to homes.
Meteorologists are forecasting B.C. is in for a hot, dry summer, and many rivers and creeks are already as dry as August.
B.C. has already spent more than 80 per cent of its wildfire budget for the summer fighting more than 500 fires across the province.
