A video showing a white man confronting a family near Toronto’s waterfront and profanely shouting they are in “my province” has prompted outrage after being viewed by thousands on social media.

The video shows a middle-aged man yelling at, pushing and threatening a family as they wait in line at the Jack Layton Ferry Terminal.

Toronto Police said they are investigating the incident as an assault.

In the video, the man can be seen repeatedly getting close to pair of younger men, who talk to him and urge several other men, women and at least two children to stay back.

“You don’t ask me a question in my f---ing province,” the older man shouts at them.

At one point, he appears to push one of the younger men, who shoves him away.

Later in the video, the man points and gestures at the family as they are talking to a security officer. “I’ll f---ing kill you,” he shouts.

The video does not show the start of the confrontation, which police said took place Monday at 6:30 p.m.

The video, which appears to have been taken by a member of the family, was uploaded the same day to a personal account on Facebook, where it had been viewed more than 730,000 times as of noon Thursday.

“Disgusting,” said one commenter. “Also embarrassing to know this idiot is Canadian ... that’s not what we stand for here.”

“I am sorry and ashamed to see that kind of disrespect and racism,” said another.

Another video taken from a different angle and posted to Twitter, shows a moment in the confrontation in which one of the younger men shoves the older man.

“Brother, get the hell out of here,” the younger man says.

In a statement, the National Council of Canadian Muslims said it is “aware of the recent viral video depicting a racist verbal assault at Toronto’s Jack Layton ferry terminal.”

“The language used in the video against the family — some of whom are visibly Muslim — is abhorrent and unacceptable,” the statement reads. “We are currently attempting to reach out to the family to make sure they receive any support they may need, including the children who were unfortunately present during this incident.”

Mayor John Tory tweeted about the incident on Thursday. “I was appalled when I watched this video. Hatred has no place in our city,” he wrote.

On Facebook, several people questioned the actions of the security guard, who can be seen addressing one of the younger men while the older man continues to shout.

Security at the Jack Layton Ferry Terminal is provided by the City of Toronto.

Spokesperson Jane Arbour said that the city will be “reviewing the incident and the staff response to ensure we are doing everything possible to provide safe, welcoming spaces for residents and visitors.”

“Racism, harassment and assault are not acceptable in our parks and public spaces.” she said.
