Crowds of people camped out or streaming onto Parliament Hill in anticipation of the 9pm show and the royal appearance. Looks like it will be another 300,000 plus event.

The Lord Elgin Hotel in downtown Ottawa served up slices from a replica of Prince William and Catherine Middleton’s wedding cake on Saturday.

Anne Donkers, owner of Sweet Indulgences in Williamstown, Ont., spent more than 100 hours working on the cake after being commissioned by the hotel for the project.

“I’ve done a lot of wedding cakes, but this one is by far the most intricate and most detailed one I’ve done. It’s also five tiers,” Donkers told CTV.ca.

Because the cake was to be served to guests and passersby, it had to be fresh on Canada Day. That meant Donkers had to put in four consecutive 18-hour days leading up to Canada Day, in order to have it ready.

She said she has a new appreciation for the royals after working on the project.

“I think it’s definitely brought me closer. I’ve always enjoyed watching and listening to anything about the monarchy, but I can’t say I was a die-hard fan. But this has brought me closer.”

Candidates stand to take the oath of citizenship, while royals look on.

Protesters gather outside the Canadian Museum of Civilization. While they don’t seem to be anti-royal, they are opposed to new citizens being required to pledge their loyalty to the monarchy.

Crowds eagerly anticipate William and Catherine’s visit.
