"Sophie Grégoire Trudeau, a gender equality advocate, will be on a panel discussion on the objectification of women in media and advertising."

There is no such thing as a gender equality advocate because there's no such thing as a gender inequality advocate. 

Sophie is obviously helplessly bored in his position of wife to the most feminine (not feminist) leader in the free world.  Instead of actually raising her kids she just outsourced that hard work to the nanny army so she can focus on unfathomably useless but more fun (!) activities like being on nonesensical panels with A-list stars. 

Hint: genders have been equal since before Sophie was born.  Ask Margret Thatcher, Indira Ghandi or Golda Meir. 

Or Wonder Woman.
