A man was being robbed when he was fatally shot in Scarborough on Friday morning, a Toronto police source says.

Just before 4:30 a.m., police responded to reports of gunshots heard in the area of Kennedy and Ellesmere roads.

"So officers went to that area. When they got there, they saw, in a parking lot, a man slumped over. They didn't know what was wrong with him. So they approached him, they checked him and he had a very serious injury," Const. David Hopkinson told CP24 on Friday morning.

Toronto paramedics said the man was rushed to a trauma centre in life-threatening condition.

The man, who is in his 50s, subsequently succumbed to his injuries, police said.

A police source told CP24 that the victim was reportedly being robbed when he was shot.

The shooting happened in a plaza in the northwest corner of Ellesmere and Kennedy Roads and the victim stumbled across the street to an Esso gas station where he collapsed, the source said.
