Victoria City Hall is fully open today for the first time since fire destroyed a vacant hotel on Monday, sending clouds of choking smoke over the city's downtown core.

A note on the city's website says city hall fully reopened this morning after it and several other nearby businesses were closed because of the potentially dangerous smoke.

The caretaker of the former Plaza Hotel has not been seen since flames broke out and officials want to speak to anyone who might know the whereabouts of Mike Draeger.

Only portions of the hotel's outer walls are still standing after the fire raged for hours on Monday. 

It flared again Tuesday and smouldered for days, preventing crews from actively searching the site for any sign of Draeger or a cause of the blaze.
