A 22-year-old Windsor, Ont., man who was shot at the Ambassador Bridge over the weekend after wielding a fake gun faces a number of charges upon his return to Canada.

The man, who has not been identified, is currently being held in custody in Detroit.

In a press conference on Monday, Deputy Vince Power told reporters that Windsor Police Services have prepared arrest warrants in relation to weapons charges and dangerous driving that will be executed if the man returns to Windsor.

Police say the man was at the Windsor-Detroit border crossing early Sunday morning.

At approximately 3 a.m., U.S. Customs and Border Protections (CBP) said the man got out of his vehicle after approaching the inspection booth and started waving what was believed to be a handgun at border officers.

A preliminary investigation by CBP later revealed that the man was holding a replica of a handgun.

Border officers then ordered the man to drop his weapon, but the suspect did not comply, CBP said in a statement issued on Sunday.

He then allegedly pointed what appeared to be a firearm in the guard’s direction. The CBP fired four rounds, one of which hit the man in the arm.

He was treated for injuries in hospital before being taken into custody.

Windsor Police said their officers had an encounter with the man shortly before the border shooting.

At approximately 2:40 a.m., officers were called to a local McDonald's after receiving reports about a man in a black Ford Explorer toting a gun.

According to police, the suspect said to the officers, “Why haven’t you shot me yet?”

"Officers were faced with what they thought was a deadly threat and they showed tremendous restraint while re-assessing the situation,” said Windsor’s deputy police chief Power. “Although at one point, police considered the use of lethal forces, they opted not to.”
