Fancy hats and fast horses: The King's Plate is back for its 164th race

North America's longest continually run horse stakes race is in Toronto on Sunday, with a name it hasn't used in more than 70 years.

After spending the last seven decades as the Queen's Plate, the King's Plate is being held at Woodbine Racetrack in Etobicoke — named in honour of Britain's ruling monarch, who is now King Charles. Despite the name change, attendees can still expect a day filled with high fashion, pageantry and, of course, racing. 

For Morgan Cameron Ross, the sheer age of the event, which began in 1860, makes it a special occasion. Cameron Ross runs the website and social media pages Old Toronto Series and was hired by Woodbine Entertainment Group to create a short documentary for this year's event. 

"The only relatively similar thing is the Canadian National Exhibition, which is younger but also hasn't been done every year," Cameron Ross said. "[The King's Plate] is kind of an elaborate, fun, consistent thing across the history of the city."

This year will mark the 164th edition of the race, according to Jim Lawson, CEO of Woodbine Entertainment Group. It will be the first race since 1951 to be named the King's Plate. The main event will kick off at 5:39 p.m., while other races will begin at 12:25 p.m.

Lawson says horse racing is a sport "steeped in tradition." And a main element of that tradition, race-day fashion, will be on full display Sunday. 

The race's website has a style guide for attendees filled with photos of light suits, long dresses, hats and fascinators. 

For the uninitiated, a fascinator is "a fascinating little object on one's head," according to David Dunkley, the official milliner — hat maker — of the event for the past 11
