While the costs are still being totalled, last week's devastating blaze that destroyed three St. Thomas businesses is now estimated to have caused more than a million dollars in damage.

Bill Todd of the St. Thomas Fire Department says the investigation is complete and there were no charges laid.

A methadone clinic, plumbing business and an auto parts store were destroyed in Thursday's blaze.

On Wednesday evening, a nearby vacant building that was slated for demolition, burned down.

The business that was in that building - Canadian Woodenware had already moved to a new location.

No charges were laid in that fire either.
