"He's the Uber!"

A video uploaded to YouTube Thursday morning shows what appears to be two taxi drivers confronting an Uber driver picking up a fare, claiming they would be reporting him to his insurance company.

Within hours, it was taken down off the video-sharing site. Instead, visitors were greeted with the message: "This video has been removed as a violation of YouTube's policy prohibiting content designed to harass, bully or threaten."

The 82 seconds-long video was later posted to LiveLeak. It shows two men walking across the street to a car allegedly parked in a taxi pickup zone. They tell the driver he's "gonna be famous" and they are going to send his plate information to his insurance company.

"No more insurance. You'll have to change the car," one says.

"This is irritating man. We're paying taxes," says the other.

It's not immediately clear where in Ottawa the incident occurred, nor when it happened.

The camera pans up to the car's roof at 37 seconds to show what looks like a razor blade mysteriously placed on top of the sunroof. It's unclear how the object got there, but the two men claim the driver has a weapon.

Amrik Singh Dhami, president of Unifor Local 1688 representing 1,800 Ottawa taxi drivers, said he doesn't condone his drivers harassing UberX drivers.

Dhami said he did not see any razor blade in the video and wouldn't support any of his drivers using weapons.

"I don't see (a blade) clearly. I can't see anything wrong in this video. They are just saying you are an Uber driver and we're going to report you to insurance," he said.

At about the 45-second mark, a woman walks up to the car and gets in.

The cabbies don't interfere with the woman getting in the car, nor the driver pulling out of the spot.

Police said they have not received any complaints about the video or the confrontation.

Uber's spokeswoman Susie Heath said intimidation tactics, like the ones seen in this video, should give way to a "constructive dialogue, focused on making available safer, more reliable and affordable, transportation options to Ottawans."

The video did not appear to be uploaded to YouTube through the Ottawa Taxi Drivers account. That YouTube account has posted two videos called "The Reality of Uber" where drivers secretly record themselves getting into Uberx rides.

However, a mirror link was posted to LiveLeak, which can be seen below.
