It's unclear if Trudeau himself was in earshot or heard the man's threats "of causing harm or death" at the August 29 event
Canadian police on Friday charged a 32-year-old protestor with uttering threats against Prime Minister Justin Trudeau at a recent campaign rally.
The alleged threats were directed at the liberal leader at a whistlestop outside of a metal fabrication plant in Cambridge, Ontario, ahead of the September 20 election.
It's unclear if Trudeau himself was in earshot or heard the man's threats "of causing harm or death" at the August 29 event, Waterloo Regional Police spokeswoman Cherri Greeno told AFP.
"As part of our investigation, we viewed videos of the event and the threats posted online and spoke to witnesses. As a result, the charges were laid," she said.
Federal police who provide security for the prime minister on the hustings also shared evidence with the local authorities, she said.
After six years in power, Trudeau has suddenly found himself in a horse race with rookie Conservative leader Erin O'Toole after calling the snap election.
At several campaign stops, protestors Trudeau has described as "practically foaming at the mouth, they were so mad at me" have shouted racial and misogynist slurs and last weekend threw stones at him.
In March, a heavily armed military reservist who crashed his truck into the estate where Trudeau lives with his family in Ottawa was sentenced to six years in prison.
The man accused in last month's incident was not named by police. He is scheduled to appear in court on September 27.
