The District of Muskoka is taking steps after Friday's blast at a construction site near downtown Bracebridge.
Workers were doing water and sewer repairs on Kimberley Avenue when the explosion occurred.
District staff are currently working with homeowners to assess the damage, board windows that were broken due to the blast, and address safety and occupancy concerns.
15 homes sustained damage.
The District is also accelerating work on the water and sewer project.
They say the infrastructure is at risk of failure and could compromise service delivery.
They have retained Fowler Construction to carry out the work.
Meanwhile, the Ministry of Labour are still trying to determine why a more significant blast took place that had been planned.
The District revealed that a sub-contractor was hired to do the blasting.
