Fire crews continue to hose down a business complex off Rothesay Avenue near McAllister Drive.
They've been on the scene since just after 5:30 this afternoon -- and -- Fire Chief Rob Simonds says the biggest challenge has been trying to get at the flames burning between a steel roof and sub-roof supported by wooden trusses.
Simonds says the combination has resulted in a fire burning with intense heat.
No one has been hurt and fire investigators are on the scene doing some preliminary work.
