Canadian Prime Minister Justin Trudeau has been hit by gravel thrown by protesters during a campaign stop.
He was returning to his bus after visiting a brewery when he was pelted by gravel.
He was not injured.
Mr. Trudeau called a snap election in mid-August, in the hope of gaining a majority government for his left-of-centre Liberal party.
But his campaign has been disrupted by demonstrations against COVID-19 vaccine mandates and other restrictions.
