A Hamilton police source confirms to CP24 that missing Ancaster man Tim Bosma's truck has been found.

Hamilton Police spent the afternoon at an address in Kleinburg, north of Toronto, where the truck was located.

Bosma, a husband and father, has been missing since Monday when he left his home with two men who showed up to test drive his black 2007 Dodge Ram 3500.

The development comes the same day Bosma’s mother issued a tearful plea for help.

Speaking to the media on Mother’s Day, Mary Bosma pleaded for the safe return of her 32-year-old son Tim Bosma, who was last seen when he went on a test drive with two strangers last Monday night.

An emotional Mary Bosma described the painful ordeal her family is going through as they await answers about her son.

“We don’t know where he is, if he’s safe and who’s got him,” Mary Bosma said.

On Saturday, the search for Tim Bosma spread to Region of Waterloo International Airport, where police taped off a hangar belonging to Millard Air.

The hangar belongs to the family of a man charged in the investigation into Bosma’s disappearance.

Dellen Millard, 27, of Toronto has been charged with forcible confinement and theft over $5,000. Police are still looking for a second man.

Millard's family founded Millard Air, a charter airline that was based in Toronto until its decline more than 20 years ago, police confirmed to CP24 reporter Cristina Tenaglia on Sunday.

Born into an aviation family, Millard set a world record at the age of 14 when he became the youngest person to complete a solo helicopter flight.

Bosma has been missing since Monday at about 9:20 p.m. when he left his family’s Ancaster home with two unknown men who showed up to test drive his black 2007 Dodge Ram 3500 with Ontario licence plate 726 7ZW.

Bosma, a husband and father of a two-year-old girl, listed the truck for sale in an online ad, which included his phone number.

Since then, police have found Bosma’s cellphone in an industrial area in Brantford, identified a cellphone number they believe was used by the suspects, and spoken to an Etobicoke business owner who went on a test drive with two men, who police believe are the same men who went on the test drive with Bosma.

The business owner told police one of the men had the word "Ambition" tattooed within a box on his wrist. Police previously said the suspect who is in custody has a tattoo matching that description.

The second male was previously described as white, in his early 20’s, and five-foot-nine or five-foot-10 with a small to medium build and dark hair. He was wearing a red hooded sweatshirt with the hood over his head.

Police are asking anyone with information to call a dedicated tips line at 905-546-2100 or Crime Stoppers.
