The 26-year-old star, who has been working as an advocate for the cause since 2014, took the time to meet Trudeau, 44, during her visit to Ottawa, reported FemaleFirst.
The pair met to discuss the issues that affect women across the world.
During their meeting, Trudeau said, "The 'HeForShe' campaign has extraordinary impact around the world, making men champions of women's issues that are everyone's issues. Her (Emma's) voice is extremely important in making people realise how important this is."
"It's been such an exciting visit for me to come visit your parliament. It was so inspiring that you made your cabinet 50/50. We're very excited that you're a 'HeForShe' Youth Ambassador. I can't wait to see what you're going to do with that title," she said.
