Calgary's Municipal Building reopened to the public yesterday.
The move came after a break-in where several fires were set.
Police say a man armed with a knife entered the building around 4 a-m last Tuesday and started lighting fires.
Although the building has reopened, several service counters inside are still closed.
The city is trying to assess the extent of the damage and to estimate repair costs and a timeline for completion.
“The Police investigation is still active, and we will not be commenting on the individual or the investigation at this point,” said the City of Calgary.
