“When I was watching it, I thought I was dreaming,” resident Mark Escobar told CP24.com.
Escobar lives on Sweetwater Crescent, near Davis Drive and Bathurst Street, and has cameras set up around his property.
He said he woke up to alerts on his phone from his camera around 2:45 a.m.  and was horrified by what he saw in the video.
“The (horses) got too close, I guess the car or one was too close to the front door, so the camera went off because usually if it’s just a random person walking down the sidewalk.  We don’t usually get notified, but I guess it was big, it was huge.  Like these things were huge,” he said.
A herd of horses is seen roaming a residential area near the scene of a serious vehicle rollover in Newmarket on November 11, 2022. 
Escobar estimates about 30 horses were strolling down his street this morning, based on dashcam footage.
The video was captured around the same time York Regional Police (YRP) officers responded to a single vehicle rollover in the same area on Davis Drive.
When officers arrived at the scene, they found the vehicle and a group of about 20 to 30 horses roaming the road.
Police said one victim was found without vital signs.  They have not yet released an update on the victim’s condition.
YRP was unable to confirm whether the collision was a direct result of the horses or whether any of the horses were injured.
The scene of an accident in Newmarket, Ont.  which saw dozens of horses freed on November 11, 2022 can be seen here. 
Police said this morning they were collecting the horses from the road.
Davis Drive is expected to be closed between Keele Street and Dufferin Street for some time as police investigate.
It is unclear how the horses ended up in the area.
Escobar said there are farms in the area, but he’s not exactly sure where the herd of horses came from.
He added that the horses left their mark during their journey through his neighborhood.
“There was a pile of it (horse droppings), like it was all over people’s streets.  It was on the sidewalk, in the streets.”
He said many of the droppings have since been cleaned up.
