Arson is believed to be the cause of a stubborn blaze late Monday night in a vacant building on the CN property at the end of St. Catharine Street.
St. Thomas firefighters responded around 11 p.m. and remained on scene until after 3 a.m. Tuesday.
The building was eventually levelled to ensure the fire was completely out.
CN police did attend, with the fire deemed suspicious in nature.
Investigators remained on scene most of Tuesday.
