The woman killed on Thursday when she was run down by a minivan on Midland Ave was a former Leaside resident sources say. The woman, 42, a mother of three, grew up in Leaside, and attended the local schools. Police say she was walking on Midland with her Labrador dog near Gilder Rd. just north of Eglinton Ave. when the northbound minivan suddenly bounced over the curb and slammed into a light standard and the woman. The dog survived. “The original 911 call we received suggested the van had swerved to avoid a dog,” said Const. Clint Stibbe, of traffic services. But our collision reconstruction officers don’t believe the dog was a factor”
