Some Canadians who have travelled to London say it's important for them to be there to witness the first coronation in 70 years.
Sally Harris from Ottawa says she and other members of the Monarchist League of Canada are hoping to watch the coronation procession under a big Canadian flag and wave at King Charles and Queen Consort Camilla as they go by.
Prime Minister Justin Trudeau, Governor General Mary Simon, as well as several Indigenous leaders and two Canadian astronauts will be in Westminster Abbey tomorrow morning to watch as Charles is crowned.
