Canadians moved by the romantic ceremony of Prince Harry and Meghan Markle experienced a brief moment of panic while watching the event Saturday.
In Markle's former adopted home of Toronto, a crowd watching the ceremony at the Princess of Wales Theatre was seized with cries of shock as the live broadcast temporarily cut out, followed by sighs of relief when the feed came back on a few seconds later, just in time for the wedding dress to be revealed.
Smiles swept across the theatre as Markle emerged in a resplendent boat-neck white gown, followed by a gaggle of pageboys and bridesmaids including Ben and Jessica Mulroney's children, who inspired awes from the crowd and a moment of levity as one of the children wiped away the sweat from their brow.
One attendee clutched her chest as Harry appeared on the screen seeming to fight back tears at the sight of his bride.
Many in the audience giggled with joy at the couple's nervous excitement.
During the sermon, the room bellowed with laughter as the camera cut to reaction shots from the pews, with royals and celebrities alike seeming bored or bemused. Some in the crowd doubled over and pointed at the screen upon seeing the expressions of the couple.
From the front row to the balcony, a hush fell over the theatre as the couple affirmed their commitment followed by extended applause as Harry and Markle — now the Duke and Duchess of Sussex — were declared husband and wife.
The cavernous theatre was packed to the brim with about 2,000 royal watchers, many bedecked in top hats, fascinators and tiaras. A line had formed before dawn, wrapping around the corner outside the theatre for the free viewing party, many of them huddled under umbrellas so they could shield their wedding best from the rain spitting from a darkened sky.
Most of the crowd rose from their red-cushioned chairs and put their hands over their hearts to join in a rendition of "God Save the Queen," during which Ben and Jessica Mulroney could be seen near the couple. The seven-year-old Mulroney twin boys, Brian and John, had the important task of holding the train on the bridal veil, as the newlyweds exited St. George's Chapel.
Whoops could be heard as the newlyweds shared a kiss on the steps of the chapel.
Purnima Kabir, 30, said she hadn't slept because she was too excited for the occasion. Dressed in a royal blue sari with lace, Kabir said she had been a royal watcher since the reign of Diana, but felt particularly invested in the soon-to-be newlyweds because of Harry and Markle's special connection to Toronto.
"I hope that they go really far, because they work really well together as a unit," Kabir said.
Her brother, Andaleebe Kabir, said as a graduate of a British prep school, he was most excited to see Queen Elizabeth as she watched her grandson tie the knot.
"We could not resist this (event). This is the theatre named for Princess Diana, and to do this here for this day, it's absolutely a wonderful tribute," he said. "We wouldn't have missed it for the world."
Lorena Erazo, who was celebrating her 38th birthday in addition to the royal nuptials, wore a wedding dress so she and her white-tied husband, Mark MacLean, could vie for the grand prize in the theatre's costume contest — a trip for two to London.
An emcee quizzed the crowd with trivia to keep them entertained during the live broadcast's commercial breaks. Union jacks waved in the air as the crowd clapped for the Queen's arrival, many taking pulling out their smartphones to take photos of the towering screen.
In Montreal's Burgundy Lion pub, several dozen people dined on crumpets and a full English breakfast in anticipation of the big moment.
Samantha Elfassy, 23, donned a red fascinator and pulled out a phone to snap some shots as the Queen arrived. She said she was most excited to see the monarch — and had taken bets on the length of the bride's train.
