Oh yeah, and there's been a few of these. The student one is unsubstantiated, but given the confirmed one where he groped a reporter it's hard not thinking there's evidence to it, especially when the Globe and Mail supposedly had the story and sat it on - and the G&M is one of the media groups which takes government subsidies.
Anyone who knows of Trudeau's drama teacher days (and slight powerlevel, I've been to the same festival with Sock Boy in attendance a few times where he groped that reporter and have chatted with people who've interacted with him) will admit he's a party animal who has abused his looks/trust fund for all they're worth. He undeniably has multiple other skeletons in the closet, but I doubt many more will see the light of day given he's a veritable pariah for Canadian politics now with little reason for journalists to dig.
