At least six people are out of work in Oliver, B.C., after the second major fire in that southern Okanagan town in the last two days.

Flames tore through Oliver Auto Wrecking Salvage just before 10 p.m. Monday night and raged until dawn.

Fire Chief Dave Janzen says the fire was so fierce the building "imploded" in the heat.

He says crews will have to wait until the rubble cools before trying to investigate the cause.

Janzen says the fire does not appear suspicious.

The nearly 100-year-old Mesa Hotel in downtown Oliver burned to the ground early Sunday morning, but no one was hurt.
