RCMP will ‘follow up’ after NDP leader heckled in Peterborough, Ontario

The incident took place on Tuesday, during an event in Peterborough, Ontario, wherein Singh was called a traitor, and subjected to vulgarities.

Deputy Commissioner Michael Duheme said that the incident was "unacceptable" and that the police would be working with party leaders and cabinet ministers on security threats.

"It's unacceptable, it’s not the first time (it has happened) … We're following up on it to determine what can be done," he told the House of Commons' public safety committee on Tuesday, according to Global News.

"When we do have a file with regards to potential threats, be it online or via phone or directly, we do engage with (federal prosecutors) to discuss the file and see if we’ve met the threshold (for criminal charges). It is a challenge, I can say from the RCMP perspective."

Singh called the experience one of the most "insulting" he's had in his time as a public figure.

"I've experienced worse in my life and experienced it regularly. So it’s not something for me; it doesn’t faze me or shake me in any way. But I am worried about what that means for politics, generally," said Singh.

Prime Minister Justin Trudeau also commented on the "hatred and vitriol" experienced by Singh, stating in a tweet released on Thursday: "The hatred and vitriol you were subjected to the other day was absolutely disgusting, Jagmeet. I agree with you that we must confront it and condemn it. It has no place in politics – or anywhere in Canada."
