Last year marked the PNE's 100th anniversary. Starting back in 1910, the event was originally an agricultural and industrial showcase.
Now, those heading to the PNE can enjoy everything from rides, to exhibits, concerts and games.
There's also a variety of fun foods to enjoy, including this year's Maple Bacon Gelato.
"We tried to come up with something new for the PNE and we just thought, something Canadian...You start tasting maple then you start chewing on some bacon," says Sonya Gabrielli with La Casa Gelato.
The PNE started out on a hot note as temperatures soared to record highs last week, but organizers say they'll still budget for at least three to four days of rain throughout the next couple of weeks.
"We cross our fingers and hope that it doesn't fall on our key days," says Laura Ballance with the PNE.
"That being said, I think that we're a pretty sophisticated group in the sense that we know how to dress for the weather and come enjoy the Fair."
Ballance adds that rain can have a dramatic effect on attendance, but hot, humid conditions and too much sun can as well.
