The Ontario Fire Marshall is investigating two overnight fires at two different abandoned buildings in St. Ann near Smithville.
Emergency crews were called to a blaze at a vacant home at 4631 Twenty Mile Rd. at 9:45 p.m. Wednesday.
Less than 30 minutes later, crews attended a second fire at an abandoned building at 2173 Regional Road 20.
The buildings are just a five-minute drive from each other and police believe the fires are related.
