It's a 109-year-old tradition.
The first Pacific National Exhibition began in 1910, and was opened by then-prime minister Wilfrid Laurier.
The fair, which became an annual event in Vancouver, was initially called the Industrial Exhibition. It was meant to showcase B.C. to the rest of Canada and the world, those behind the fair today say.

At the time, it was the second largest in North America, surpassed only by the New York State Fair.
The exhibition that is now more than a century old morphed over time from an industry showcase to a place for families to try strange snacks, win prizes in games and prove their nerve on rides.
Photos below show the fair as it was. All images below are from the City of Vancouver Archives' Pacific National Exhibition fonds.
