Residents living on a street in Ottawa's Westboro neighbourhood say they're frustrated and stunned after waking up Sunday morning to a rash of vandalism.

Almost 20 cars along Tweedsmuir Avenue, near Byron Avenue and Clare Street, showed signs of damage, including smashed windshields, broken side mirrors, dents and scratches.

Martin Gravel and Kathleen Michaud told CBC News they were shocked to discover the extent of the vandalism.

"I was really stunned, I wasn't expecting that to happen in Westboro," said Gravel, who only moved to the neighbourhood a month ago. "Basically they did the whole street up to Westboro Station."

While his SUV had two completely destroyed windows, nothing was taken from the vehicle — including the spare change sitting inside.

"It's difficult to understand. I don't get it," he said. "Just to do damage for damage's [sake.]"

The pair does have a motion-activated doorbell camera, but it isn't able to sense movement from as far away as the street, Gravel said — leaving them with no video footage of the incident.

Police reports filed

Several residents, including Mike Jennings, said they'd filed complaints with Ottawa police.

The windshield of Jennings' blue Hyundai was covered in a spiderweb of cracks Sunday morning, with clear footprints showing where someone had stood on the hood of the vehicle.

"This isn't really the neighbourhood you expect mass vandalisms to happen in," Jennings said. "I'm fairly convinced it's not somebody who lives around here."

A police news release said 19 vehicles had been reported damaged, and the investigation is ongoing.

'Certainly not great'

Another resident, Martine Courage, said she heard suspicious noises coming from outside her home around 3 a.m., but couldn't see anything when she looked out the window.

She said her daughter first noticed the vandalism the next morning, along with a sizeable rock that appeared to have been used to inflict the damage.

Courage said she'd lived in the area for 18 years, and while similar, more minor incidents have happened before, the needless destruction was still annoying.

"I'm not shocked, but it's certainly not great to have your vehicle damaged like that for no particular reason," she said.

"We've talked about getting a security camera in the past, [since] it would be nice to have some kind of evidence that we could use to help to stop this."
