Justin Trudeau dresses as Clark Kent for Question Period, reveals Superman costume after

OTTAWA – It’s a bird. It’s a plane. No, it’s Justin Trudeau.

The prime minister is disguised as Clark Kent as his Halloween alter ego for 2017.

On his way to question period today, Trudeau descended the stairs sporting slicked-down hair and a blue suit with a bright red tie, surprising the assembled staff and journalists who were waiting for him.

As he got to the bottom of the stairs, he opened his shirt to expose the Superman costume hidden underneath, quipping, “It had to be done.”

Trudeau has a history of having fun with Halloween, choosing Han Solo of “Star Wars” fame for his first year in office.

Last year he went as a pilot from the French children’s book “Le Petit Prince,” while his youngest son, Hadrien, went as the title character.
