There will be free hot chocolate and Beavertails up for grabs on Wednesday night as the capital celebrates the holidays.

Parliament Hill will be illuminated with Christmas lights as part of the 32nd annual Christmas Lights Across Canada celebration.

Starting on Wednesday through until Christmas Day there will be a magical lightscapes multimedia show that will be projected on to the Parliament Buildings every night from 5:30 p.m. until 11 p.m.

This year, they've also added an interactive art installation called Prismatica.

The 24 giant prisms reflect different colours and spin by hand or in the wind.

The official illumination ceremony starts at 7 p.m.
