Sophie Grégoire Trudeau opens market, marks Day of the Girl

Also joins Instagram during Toronto visit Tuesday

It was a big day for Sophie Grégoire Trudeau.

In honour of International Day of the Girl, Madame Grégoire Trudeau opened the Toronto Stock Exchange, spoke to a group of girls about career opportunities, and finally joined Instagram — all on Tuesday.

Trudeau launched her Instagram profile after having resisted social media, even after her husband became Prime Minister. In less than 24 hours, Madame Grégoire Trudeau has been followed on Instagram by more than 16.8 thousand people and counting.

“As a 41-year-old mother of 3 young kids and activist for gender equality and womens’ and girls’ rights: It’s time,” Trudeau wrote in her first Instagram post ever. “On this international #DayoftheGirl, it’s time to share the amazing journey we’re on together.”

Earlier that same day, Trudeau rang in a new trading day, joined by representatives from Plan International Canada, G(irls)20 and FitSpirit, organizations devoted to the advancement of girls.

Mary Lou Hukezalie, senior vice president of TMX Group, said it was an honour to open the market with Trudeau.

“Today was a proud day for TMX as we were fortunate to lend visibility and support to a cause that has a positive, lasting impact on the lives of so many girls around the world,” Hukezalie said.

Arguably one of the most influential women in the country, Trudeau was not the only one to have a big day on Tuesday. Young girls across Canada were invited to fill some pretty prominent seats, seats in classrooms, boardrooms, courtrooms, press rooms and the Senate. The exercise was part of Plan International’s #GirlsBelongHere initiative to advocate for equal opportunity.

Trudeau is a global ambassador for Plan International Canada and, in a video she made for the organization two weeks ago, said she is “thrilled to create momentum” for the movement.

“Girls belong here and everywhere else where decisions are made,” Trudeau said. “Girls belong where they want to be. Girls have the right to reach their full potential and become who they want to become.”
