The Alliston Walmart reopens today following a fire earlier this month.
The location has been closed since April 7th when a 15-year old girl set fire to part of the store.
Nottawasaga OPP found and arrested the girl at the scene who set fire to the central part of the store sometime after closing at 10pm.
The sprinkler system in the store turned on which helped New Tecumseth firefighters extinguish the fire.
However, the water from the sprinklers, combined with the smoke, caused most of the damage.
The health department determined most of the food products suffered smoke damage and needed to be removed.
Officials say this past week was spent replacing merchandise.
They went on to say some items may not be available when the doors open at 7am, and they thank the community for their patience.
