A fire at a vacant building on the grounds of former Canadian Forces Base Cornwallis in the Annapolis Valley Thursday morning has been deemed suspicious by RCMP.

Darryl ​Jelfs, the chief of the Bear River Fire Department, said 65 to 75 firefighters from six different fire departments responded to the blaze at 7:50 a.m.

Jelfs said they used two aerial ladders to fight the flames, which were shooting out the roof on the second level of the vacant building, which once served as barracks for the base.

No one was injured.

In September, a different building caught fire on the base. 

The chief of the Digby Fire Department, who was not at the scene, said he could see smoke from about 15 kilometres away. The building was extensively damaged.
