Toronto mayoral candidate Olivia Chow would not put any dip on her Pringles Tortilla chip, she says.

"I don't think you need to dip this chip," says Chow when approached by the Pringles interviewer at this week's Labour Day Parade.

John Tory, Chow's rival in the race, says, "you don't need to dip to get the zip."

It is the first time either candidate has appeared in outside of campaign advertisements.

Pringles has embarked on the peculiar ad campaign — a rare mix of contentious city politics and multinational commerce — since Labour Day.

In incumbent mayor Rob Ford's last public appearance, Matt, the Pringles pitchman, can be seen walking along side the mayor asking about the chips.

Although some campaign signs appear in the commercial, it falls outside the rules of election campaigning since no campaign paid for it. 

The Chow campaign says it didn't even know about it. Ford appeared surprised by the questions.

"I didn't even get a free sample," says Chow's communications director, Jamey Heath. "It's a Pringles ad. It asks how she eats chips."

Pringles Canada says the advertisement does not intend or imply any endorsement. The video ad was released the same day Chow made an announcement about school nutrition.

On Pringles Canada's Facebook page, the reaction to Chow's appearance was mixed.

Some commenters posted photos of themselves at the same parade with the mayoral candidate. Some commenters vowed never to eat a Pringles product again.
