The People's Party of Canada dropped the riding President Shane Marshall of the Elgin Middlesex London riding association, over the stone throwing incident at a Trudeau event.

"We expelled him as soon as it was confirmed that he was the one who threw the gravel," PPC spokesperson Martin Masse said "We haven't confirmed the other allegations, and frankly we are busy running an election campaign and don't have time to investigate someone who isn't involved in our party anymore."
