A fire broke out in yet another vacant house in Vancouver just hours after police issued a public plea for help in their investigation.

Nearly 40 firefighters responded to a fire at a home on Cambie Street near 41st Avenue Thursday night.

Officials said it appeared as though someone had a fire in a fireplace but also in the middle of the floor.

Vancouver Fire Asst. Chief John Dennis said firefighters are responding to similar calls almost every night.

“All along the Granville, the Oak Street, the Cambie, the Main Street corridors are abandoned homes. And people are finding their way in, and they’re making them their homes until they light a fire and something goes wrong,” he said.

There have been at least 26 suspicious fires in vacant homes in Vancouver this year, including nine since late October.

Investigators are trying to determine who might be responsible and whether any of the fires may be connected.
