This prompted Mr Trudeau to ask the student to use the term "peoplekind" instead of mankind.
A spokesman for Mr Trudeau quoted by the Canadian Broadcasting Corporation did not comment specifically on the criticism, but said: "The Prime Minister is a proud feminist, and our government's policies reflect our commitments to equality".
He interrupted a woman named Aimee when she said the word "mankind", telling her: 'We like to say peoplekind, not necessarily mankind, because it's more inclusive'.
Of course, this isn't the first time the prime minister has come under fire for his actions and comments regarding women and feminism.

He broke into a woman's question about charitable status for her female-centred church when she stated: "maternal love is the love that's going to change the future of mankind". Trudeau told her he preferred to say "peoplekind".
"Daniel Dale, a Toronto Star correspondent said that the "US right-wing pile-on" was misleading as Trudeau was lightly ribbing a woman who was rambling about the power of women" and accused it of omitting context.
It comes after the Canadian national Senate last week gave its final approval to a bill that would remove the word "sons" from the "O Canada" national anthem in order to make it gender-neutral.
