Excitement is building on both sides of the Atlantic as millions of people prepare to watch Prince Harry, sixth in line to the thrown, marry American actress Meghan Markle in what is expected to be a lavish ceremony filled with pomp and pageantry.

Guests are expected to start arriving at around 11 a.m. local time (6 a.m. EDT). The ceremony itself is expected to get underway at St. George’s Chapel in Windsor Castle at noon local time (7 a.m. EDT). Live coverage of the special day on CP24 will start at 4 a.m. EDT.

Prince William is the best man. Markle’s mother, Doria Ragland, will travel with the bride to the chapel. Prince Charles will walk her down the aisle. Markle’s father, Thomas Markle Sr., was supposed to do the honour, but had to drop out just days before the ceremony because of medical concerns.

The Queen will attend along with her husband Prince Phillip. Camilla, Duchess of Cornwall, Katherine, Duchess of Cambridge, and other members of the royal family will also be present.

Romance unfolded in Toronto

While people around the world will be tuning in to watch the royal nuptials, Canadians and Torontonians in particular are watching with keen interest as a love story that unfolded in this city reaches its ‘happy ever after’ moment on the other side of the ocean. 

Markle grew up in Los Angeles, but lived in a house in Seaton Village while she worked on the television show “Suits” from 2011 until 2017.

It was during that time that she started dating Prince Harry, with Harry often spotted slipping in and out of the city for visits.

Toronto played host to the couple’s very first public appearance together when Markle walked out hand-in-hand with the prince at a wheelchair tennis match at Nathan Phillips Square during the Invictus Games in September.

The moment caused a media frenzy and marked the start of their public life together.

During her time in Toronto, Markle was often seen at hotspots around town and moved in circles that included other notable Toronto residents.

One of those people was stylist Jessica Mulroney, who is also the wife of Your Morning Host Ben Mulroney. Markle and Jessica Mulroney became close friends and the Mulroney family is expected to take part in Saturday’s ceremony. Kensington Palace has said that seven-year-old twins Brian and John Mulroney will act as page boys, while their four-year-old sister Ivy Mulroney will be a bridesmaid. 

Markle left Toronto to move to London in November, but continued to show off her association with the city.

Toronto got a fashion nod when Markle wore a white wool wrap coat by local designer label Line as the couple announced their engagement in November. The coat was subsequently renamed the "Meghan" and quickly sold out.

Markle has frequently been spotted wearing various other Canadian and Toronto-based designers.
