Darren Werner has been missing since Sept. 16.

The 58-year-old Niagara-on-the-Lake resident was last seen in NOTL near Townline Road at 9 a.m. on that day, travelling in an unknown vehicle, according to Niagara Regional Police.

Police and his family are worried about Werner's welfare.

“It’s been six days since the disappearance of Darren Werner,” his ex-sister-in-law Kristyn Dekker-Davies wrote in a Facebook post on Sept. 21.

“A thorough grid search of Darren's property was completed today by NRP Tactical Unit. Obviously we did not find Darren.”

Werner is the property owner of 1238 Townline Rd., which was the site of a major fire in February.

Davies said Werner’s phone has been off since Sept. 16, all of his vehicles are still on his property, his bank account has not been accessed and he has not left the country.

“This is completely out of character for Darren,” she wrote.

Werner’s property was being used to house several businesses including an auto-repair shop. Community members used the property to store boats, race cars, classic cars and vintage military vehicles among others.

Damages from the fire were estimated at $2.5 million and Werner told media members the property was insured.

Werner is white, 5 foot 11 and weighs roughly 180 pounds. He has short grey hair and brown eyes.
