A weekend fire caused more than half a million dollars in damage to a Windsor bakery and the owners are trying to pick up the pieces.

Investigators were not able to determine what caused the fire at the Pastry Table Cafe on Tecumseh Road East, but Windsor Fire and Rescue has determined the fire was not suspicous.

"We’ve completed our investigation, at this point it’s been turned over to the owner. The insurance company and their adjusters will be in and they’ll bring in electrical engineers to look at some of the equipment and make some determinations," said chief fire prevention officer Lee Tome.

The fire broke out at the family-owned bakery at about 3:30 a.m. Sunday morning.

"They’re very distraught, this is their livelihood. This is what they’ve been doing for the past 18 years. They enjoy working with the community," said Tim Markalj, son in law of owners Angelo and Filomena Delicata.

The owners were too upset to speak with CBC News, but Markalj says they will bounce back.

"Currently they’re in the process of going through some of the paperwork they were able to recover yesterday to try and contact customers who have outstanding orders to let them know what’s going on," said Markalj, who added they will either make alternate arrangements or return money to customers.

Damages are estimated at $600,000. Officials say there's heavy smoke damage inside the building, but the fire was contained to the Pastry Table Cafe.
